Different Types of Relay.
Depending on the operating principle and structural features relays are of different types such
as electromagnetic relays, thermal relays, power varied relays, multi-dimensional relays,
and so on, with varied ratings, sizes and applications.
This video main aim is to give a brief idea about various relays that are employed for
a wide variety of control applications.
Some of these relays are described this video.
Electromagnetic Relays.
These relays are constructed with electrical, mechanical and magnetic components, and have
operating coil and mechanical contacts.
Therefore, when the coil gets activated by a supply system, these mechanical contacts
gets opened or closed.
DC and AC Relays.
Both AC and DC relays work on the same principle as electromagnetic induction, but the construction
is somewhat differentiated and also depends on the application for which these relays
are selected.
DC relays are employed with a freewheeling diode to de-energize the coil, and the AC
relays uses laminated cores to prevent eddy current losses.
Attraction Type Electromagnetic Relays.
These relays can work with both AC and DC supply and attract a metal bar or a piece
of metal when power is supplied to the coil.
This can be a plunger being drawn towards the solenoid or an armature being attracted
towards the poles of an electromagnet as shown in the figure.
These relays don't have any time delays so these are used for instantaneous operation.
Induction Type Relays.
These are used as protective relays in AC systems alone and are usable with DC systems.
The actuating force for contacts movement is developed by a moving conductor that may
be a disc or a cup, through the interaction of electromagnetic fluxes due to fault currents.
These are of several types like shaded pole, watt-hour and induction cup structures and
are mostly used as directional relays in power-system protection and also for high-speed switching
operation applications.
Magnetic Latching Relays.
These relays use permanent magnet or parts with a high remittance to remain the armature
at the same point as the coil is electrified when the coil power source is taken away.
Solid State Relays.
Solid State uses solid state components to perform the switching operation without moving
any parts.
Since the control energy required is much lower compared with the output power to be
controlled by this relay that results the power gain higher when compared to the electromagnetic
relays.
These are of different types: reed relay coupled SSR, transformer coupled SSR, photo-coupled
SSR, and so on.
The above figure shows a photo coupled SSR where the control signal is applied by LED
and it is detected by a photo-sensitive semiconductor device.
The output from this photo detector is used to trigger the gate of TRIAC or SCR that switches
the load.
Hybrid Relays.
These relays are composed of electromagnetic relays and electronic components.
Usually, the input part contains the electronic circuitry that performs rectification and
the other control functions, and the output part include electromagnetic relay.
Thermal Relay.
These relays are based on the effects of heat, which means - the rise in the ambient temperature
from the limit, directs the contacts to switch from one position to other.
These are mainly used in motor protection and consist of bimetallic elements like temperature
sensors as well as control elements.
Thermal overload relays are the best examples of these relays.
Reed Relay.
Reed Relays consist of a pair of magnetic strips (also called as reed) that is sealed
within a glass tube.
This reed acts as both an armature and a contact blade.
The magnetic field applied to the coil is wrapped around this tube that makes these
reeds move so that switching operation is performed.
Relays are also available with different pin configurations like 3 pin, 4 pin and 5 pin
relays.
The ways in which these relays are operated is shown in the below figure.
Switching contacts can be SPST, SPDT, DPST and DPDT types.
Some of the relays are normally open (NO) type and the other are normally closed (NC)
types.

Favorite 2016 Debuts & New To Me Authors - Duration: 9:31.
Hey guys! It's Trina and this is my
December Monthly Recommendations video.
Our topic for this month was new to us
authors. We thought it would be a great
way to end the year by reflecting on the
authors that we discovered for the first
time this year. In 2016 I read a total of
twenty authors that I had never read
anything by before. Some of these I read
more than one book by them this year.
There were 12 authors who had backlist
titles, so some of these authors have had
dozens of books published in the past
or they have multiple series and I just had
never read anything by them before. Those
12 authors were Jojo Moyes, Michael Punke,
April Genevieve Tucholke, Adam Silvera,
Shannon Hale, Robin Talley, Melissa Grey,
Marisha Pessl, Becky Albertalli, Jessica Love,
Alexandra Bracken, and Ann Brashares.
The other eight authors who were new to
me this year were actually debut authors
so the first book that they've ever
published came out in 2016 and those
eight authors were Emily Henry, Emily France,
Roshani Chokshi, Jeff Zentner,
Shannon Parker, Sara Ella, Meredith Russo,
and Julie Eshbaugh. So out of these 20
authors there are ten books that were my
favorites of this list that I want to
recommend to you guys today. The one I'm going to
start with is the Sisterhood series by
Ann Brashares. She has many books out and I
read her entire Sisterhood series this
year. It's about a group of four girls
that have been friends all of their
lives and in the first book they are
facing their first ever summer apart and
they vowed to keep in touch by sending
each other letters and mailing this
pair of jeans that somehow fits all of
them back and forth hopefully to have
like these grand adventures and great
experiences while wearing these jeans
because they feel like the jeans are
kind of a symbol of their bond and their
friendship. There are five books in this
series and one of the things that I really
love about it is that it grows with the
characters from high school, to college,
and then the last book does have a big
time jump and follow them as adults.
I love many aspects to the characters and
their lives and I really loved the
friendships and how that was really the
forefront of the message in these books.
Next, I finally read Alexandra Bracken.
I ended up reading two books by her this
year and she's probably the most known
for her The Darkest Minds trilogy but I
actually started by reading Passenger
which came out in January and I really
had trouble getting into this book
but then by the end I had totally turned
around and was really really enjoying it.
Having read passenger first even
though it's her most recent book, that
really made me want to get into her
writing more so then I went back and
read The Darkest Minds. If you aren't
familiar with either of these, Passenger is
a time travel story. You travel to so
many different times and locations
around the world. I really enjoyed the
travel aspect, I thought she really
nailed the atmosphere of each location. I
really felt like I was traveling the
world in that book. The Darkest Minds is
a dystopian trilogy where in the future
teenagers have developed these psychic
mind powers. I really enjoyed both of
these and would recommend them both. The
next author who was new to me this
year that I would recommend is Jessica
Love. I read In Real Life by her and I
really really enjoyed this one. It is
about two people who have an online
friendship and one of them develops
feelings for the other one and she
decides to actually go and meet him in
real life and see if they have more than
a friendly connection. When she does
meet him she finds out that he may not
have been totally honest about some of
the things that she thought she knew
about him. I found the premise of this
book like totally interesting - this whole
thing with online friendships, online
dating, people portraying themselves in a
certain way online. It is a pretty fluffy
kind of contemporary novel but I blew
through it in like just a couple of
sittings and I really appreciated that about it.
Becky Albertalli was also a new-to-me
author this year. I read Simon vs. the
Homo Sapiens Agenda. This book was my
favorite book of the year. It was
number one in my best books of the year
list. If you missed that video, by the way,
I'm gonna put a link to it down below
where I do talk about my six favorite
books of the year.
Simon vs. the Homo Sapiens Agenda
was number one. If you aren't familiar with
this one, it is about a boy named Simon
who is not out to school or to his
family but he is gay.
He has a crush on a boy that he knows
online and all he knows about this boy
is his nickname and that he goes to his
same high school but he's not out either.
So Simon is having these feelings and
maybe wanting to come out and also
figuring out who his online crush is. It's
so adorable and it really really
captured the feelings of high school
crushes and online relationships and
like friendships to romance and stuff like
that. I really enjoyed this book so much
and just... I loved it. I loved it. I loved it! It's my
book of the year, of course I loved it.
This year I also read Melissa Grey for
the first time. I read The Girl at
Midnight and its sequel, The Shadow Hour.
This is an urban fantasy series that has
a lot of elements to it that I think
fans of the Daughter of Smoke and Bone
series would love. Like, there's just a lot
of good things about it that are common
in very popular YA series. It is also
own voices in terms of the Latina main
character and there are some male/male
relationships and I just thought it was
a very exciting thing so I enjoyed it and I
would definitely recommend it.
Next, I really enjoyed Night Film by
Marisha Pessl. This is an adult mystery
novel and I just enjoyed this book and
like how it made you wonder which thing
was true because it kind of set up the
story to go a couple different ways. It's
about a director who's very famous and
very reclusive. His daughter ends up dead
one day. It was declared a suicide by
police but there's a little bit of like
evidence that says maybe she was
actually murdered. And the main character
we follow is a journalist who decides
he wants to start investigating this
case because something just has never
felt right about this girl and her
father and maybe like their whole family
and the relationship they have with each
other and he thinks she was being
haunted by some kind of demons from her
past and he's trying to figure out what
that was. The next four books on this
list are all of my debut authors who I read
this year, so first of all I have to
mention Sara Ella. She wrote
Unblemished. She is one of my good
friends and she is a fellow booktuber so
I'm gonna have a link to her channel down below.
Unblemished is an urban fantasy series
about a girl who discovers that there
are parallel worlds and there's another
parallel world where she finds herself
wrapped up in this ongoing eternal
battle between light and darkness. There
are so many fairytale-esque themes in
this book and I just really think if you
like fairy tales you would enjoy this one too.
This is the start of a trilogy so I did
feel like it was kind of complicated for
me to keep up with all the characters
and all of the world building that was
going on but this is a story that was very
unique and it did stand out to me and I
can't wait to see where this series goes.
I also really loved The Girl Who Fell by
S. M. Parker. This is another book that made
it into my top six list of the year. It
just was such an impactful story to me.
This one is about an abusive
relationship. You know that from the book
jacket, from the summary, and you're
watching these two characters meet and
how they get involved with each other
and then how the main female character
figures out that this is not a healthy relationship.
The writing was really easy to read, it
kept me engaged. I like that in some
parts this book took stereotypes about
abusive relationships and ran with it
because those things are stereotypes for
a reason, and then in other ways the book
kind of broke out of different
stereotypes. I do feel like it's such an
important thing to talk about in YA
fiction. This is definitely not like the
only book out there that handles abusive
relationships for young adults but we
need more like this and I really
appreciated that this book was giving us
a story like that.
Next is Meredith Russo who wrote If I
Was Your Girl. This is a book about a
trans girl and the author is also a
trans woman so it is own voices.
Primarily, this is a contemporary romance.
This is about Amanda after she has
transitioned, having her first relationship
with a boy and she's moved to a new
school where people don't know that she
is trans. We also have flashbacks that
show what it was like being bullied as a
young child. There were a couple of
things about the writing and like the
progression of the story that weren't my
favorite but this is still a book that I
really loved. I would consider it one of
my favorites of the year even though it
didn't quite make the top six but I
highly highly recommend this one.
And finally I would recommend Ivory and
Bone by Julie Eshbaugh. This is the first
book in - I think it's going to be a
trilogy. This one is set in a prehistoric
time period which I've never really read
about. It is kind of a romance but it's a
very slow burn romance. like hate to love
type of situation. It is very reminiscent
of Pride and Prejudice and that is because
it is a kind of inspired by, very loose
retelling and I knew that going into
this book and it made it so fun for me
to read it and kind of figure out which
character was representing which
original character from Pride and
Prejudice. Another thing that was
really interesting to me about this book
was the way that it was told. I know that
this did not work for everyone but it
really worked for me - it is told in kind
of a second person narrative. The book
starts with our character Kol telling
Mya the story of how he met her. That,
plus the prehistoric time period which I
have never really read anything set at
that time just made this story really
refreshing and unique to me and I really
really enjoyed it.
So those are my 10 favorite books that
were by new to me authors that I
first read this year. I definitely am
looking forward to reading more by
all of these authors. I do also want to
quickly say that although they did not
make it into my top 10 favorite books
Robin Talley, Adam Silveira, and Roshani
Chokshi are also new to me authors this
year that I want to read more by. Let me
know who your favorite newly-discovered
authors this year were down below.
Thank you guys so much for watching. I
hope you will join in with our monthly
recommendations topics in the new year.
Our topic for January is historical
fiction and I need some recommendations
from you guys! Thank you for watching
and I will see you in the comments. Bye!

World of Tanks PS4 / XBOX - AMX CDC - High Caliber, Sniper - subtitle text commentary - Duration: 8:47.
AMX CDC - Prokhorovka - Encounter
7 vs 7 top tier game
just finished the CDC ops and got the tank
my crew has no crew skills
the CDC is a very fast tank with a powerful engine
it doesn't really turn quickly however
but the power to weight ratio is crazy at 35+
together with 10 degrees of gun depression
this tank goes up hill and works ridge lines like a boss
the gun is a 90mm, standard for tier VIII medium
212mm of pen with AP and 259mm with APCR is great
DPM and accuracy are average for balance
here I go up the mid ridge to spot, important in this map
and spotted a Freedom, snap shot and pen him with AP
not a lot of tier VIII tanks can pen the Freedom's front
I don't want to be focused as this tank has no armor
the armor is so thin that most HE rounds will go through
I tell my platoon mates to go pressure the cap
by doing so, we can force the reds to defend
spot and snap shot the Freedom, AGAIN lol
as it is a 7 vs 7
it is likely that the entire enemy team will go to the cap
IF we get there first
I don't want to hang around too long without suppport
think I am not spotted at this distance
hit the Freedom again as he thought I was still there
Tiger II heading to the cap
T25/2 and I both hit him
I was spotted however
let's run away
the dispersion value with the CDC is quite bad
which affects your actual aim time
now check out how the CDC climbs hills
going up nearly 30km/h
never going to hit this so I didn't fire
the Freedom is pushing forward
and although he is heavily wounded
he will spot our entire team if he makes it to the ridge
I decided this can't happen
our T25/2 was shut down
hopefully I can two-shot the Freedom
load up APCR to limit chances of bouncing
ISU-152...hope he doesn't focus on me
bounced the first shot off his front hull
took an extra hit but that's okay
ISU was brutally shut down as well by the team
argh stupid train wreck
go to F6 and put the flanking shots in
KV-85 spotted, the only tier VI in this game
damn ISU get out of my way
this guy apparently tunnel vision on the hill
and from now on it's just easy damage
GwTiger P shut down my platoon mate though
telling my KV-4 platoon mate to push up
use the rock to avoid arty
bounced on the side of the KV-4
shut down the KV-4
shut down the Tiger II but GwTiger P hits our KV-4
track the Lower and our IS-6 puts him down
load HE for the arty
spotted him!
HE wrecks him for 359
and win the game
1,925 base exp but no Ace Tanker
Thanks for watching!

Aushi Mizani | Closing the Sale - Duration: 1:43.
Hey Z here with Aushi Mizani and today
we're talking about the number-one skill
in closing sales believe it or not that
skill is silence
wow you don't have to do a lot to be
quiet you have to do a LOT to be quiet
so once you have made your closing
question let's say you are asking mr.
customer would tuesday work better for
you or thursday once you make that
question the next person that speaks
buys and if you're the next person to
speak you have just purchased a lack of
a sale
silence is key here the power exchange
that's going on in the conversation is
such that the next person to speak is
the buyer if your customer speaks next
and they have a question that gives you
the opportunity to re-educate them and
ask another closing question again once
you ask a closing question
don't say a damn thing it once took
seven minutes for a client to answer me
and it felt like seven years you know
what it was worth it i got the sale and
the client stayed with us for a couple
years so the number-one skill in closing
sales is silence learn when to shut your
mouth once you make your closing
statement and you're closing question
don't speak again until they speak and
that my friend will close you easily
twenty-five percent more sales than your
enjoying right now so let me know in the
comments below how it's going and if you
have any questions feel free to ask
I look forward to chatting with you
about your closing successes

Bangkok Bites Into Thai Street Food at Ratchawat Market! - Duration: 2:52.
Today you get my tip on a place that's the perfect size for an off the beaten path morning
adventure in a Thai market.
Introducing Ratchawat market, located in the old part of Bangkok about 15 minutes or more
from Victory Monument depending on traffic.
Ratchawat is a special market because it's not so enormous that you get lost, it's
overrun with food vendors so much of the market spills out on to the sidewalks, and it's
surrounded by a great collection of tasty restaurants, all on the same street!
This means you can grab ingredients from the fresh market, pick up food to take home, and
have an outstanding Thai street food meal all in the same place.
I particularly like the fried pork vendor at the front of the market and the four or
five traditional Thai dessert vendors near the exit.
Because the of the market's old town location and size, it's often overlooked for the
larger and more central markets around Bangkok.
I recommend showing up to the market during the lull between the morning rush and lunch
rush, at about 9 or 10am.
This will give you plenty of time to leisurely explore, taste, or even organize your own
street food tour hopping from stall to stall.
For example, There's an old rickety fish noodle stall called Nai Joe (aka Joe's Place),
which looks as though it's never been upgraded.
The tables are worn out and wobbly, it's noisy thanks to the classic ice grinding vendor
next door, but it serves delicious noodles and feels like the real Bangkok you've been
craving.
You can also grab a hungry friend like TJ, a travel vlogger from the channel Cup of TJ,
and roll up to Sawadee Pad Thai, one of my favorite spots in the city for skillet fried
pad thai noodles and oyster omelettes.
You'll find them continuously being worked by two to three chefs out front, conjuring
up a cloud of smoke and noise as they cook.
The restaurant is larger than it looks and has an extended dining area in the back.
However I like to sit up front and order stir fried turnip cakes, and their special pillowy,
egg wrapped pad thai, while I watch the furiously cooking chefs and people walking by.
The fun of hunting tasty eats in this off the beaten path market, combined with delicious
nearby restaurants earns this experience a total 5 out of 5 points.
Are you ready to kick it in Bangkok's Ratchawat market?

When Dreams Come True, Don't Complain - Sadhguru - Duration: 2:11.
Juhi Chawla: But, Sadhguruji,
suppose we say this to the common man,
who has a little house
Sadhguru: Where did you meet a common man?
Juhi Chawla:(Laughs). I'm imagining it,
that you know,
they have so many chores to do in a day
Sadhguru: No, what I'm, saying is
every… every man or woman think they're special, believe me
Juhi Chawla: Oh yes.
Sadhguru: Yes.
So where did you meet a common man, I'm asking (Laughter).
Juhi Chawla: Oh!
I will come to this as well actually.
I want to ask you this.
Now, I'm talking about a household
where people have to literally go to work every day,
to pay their rents, you know
children have to be educated,
food has to be on the table.
They are busy morning to night –
they go to office,
maybe their boss is not pleasant with them,
they come home – maybe they have a little tiff with their wife,
the children have their own little wants and you know demands
and… Dealing with so much,
how can they keep reminding themselves that you know
it's all in my mind and I have to be
Sadhguru: No, no, no, first they have to know this,
these are all the things
these are all not punishment imposed upon them
these are all the things that they always wanted.
They wanted a job and they got it.
Juhi Chawla: Yes.
Sadhguru: They wanted a wife or a husband, they got it.
They wanted children, they got it.
They wanted a car in which they're stuck in the traffic jam (Laughter),
okay.
Juhi Chawla: Yes.
Sadhguru: I'm saying these are all things that they wanted.
So they must understand,
if their dreams come true, they are a big mess (Laughter/Applause).
Juhi Chawla: Yes, actually I have heard this–
"Be careful what you ask for,
because you might get it" and yes we've all got it.
Sadhguru: So they're complaining about things that have worked in their life (Laughter).
