What is the difference between control panel and MCC?

You know what is control panel and what are the components used in the control panel. Now we will discuss about difference between control panel and MCC. You might have faced this question in some interviews.

MCC stands for motor control center. It consists of feeders for motors and blowers. Feeders are designed according to the motor rating. In most of the MCCs, auto/manual provision will be there. With manual provision motors can be operated manually. In auto provision external signal is required to start the motor. The signal is given by the control panel. Indicators for the motor operation also will be present in control panel.

Control panel consist of a controller. Controller may be PLC, DCS, relay or some other type. It gives digital signal input signal to the MCC panel to start the motor. Control panel works based on the PLC /DCS program or the relay logic.  Instruments are normally connected to control panel. Indications for the interlocks also will be there in control panel. Nowadays single panel is used of using separate control and MCC panel.

How to read electrical relay diagram? [Standard symbols used for drawing electrical relay diagram]

In one of the previous post in instrumentpedia I have described how to read an electrical drawing. Now lets look what is electrical relay diagram. Here I am giving the standard symbols used for the electrical relay diagram. In earlier days instead of PLC or DCS like controllers relays are used as controllers. Nowadays also for controlling small systems relays are using as controllers. Comparing to other controllers it is very cheap. Electrical control circuits are drawn with the standard symbols which are given below.

Components used for making a electrical control circuit and its standard symbols.

Switches.
Selectors.
Push buttons.
Contacts.
Coils.
Motors.
Pilot lights.
Alarms.
Connections

The only thing left.

Seriously. I can't even tell count the number of times this has happened to me.

Left-handed people are the silently oppressed in this world. 

The God of Thunder.

I saw the midnight release of the Thor movie, which is now out in most theaters.

Long review short, I enjoyed it. I didn't fall in love with it like I did Ironman, and I didn't detest it. Perhaps I am biased. I am a superhero fan, and would most likely have a somewhat lower opinion if I was not.

Though, as I said, I enjoyed it. I was entertained. Ultimately that is the point of movies.
There was plenty of action, plenty of laughs, and enough special effects to make you say "whoa, what the shit" repeatedly. Although the camera movement was a little too fast for my taste, blurring out a good portion of the fight scenes.

Also eye candy. Mostly for the women, but still. They give you Natalie Portman, so stop complaining. Honestly, her acting could have been much worse. I guess that's a high point?
The movie throws you in at a comfortable starting point, and introduces the characters and backstory at a relative pace. You don't have to be a comic fan to understand what's going on, which is exactly what they were going for.

Then you get some cool fighting scenes, with giant face-lasers, a giant ice-themed Rancor and a bunch of blue people from Avatar.

[If you want to keep the movie a surprise, I would stop reading about here.]

After that some plot is thrown your way, and Thor is exiled to Earth (a.k.a Midgard). For a day. This is ridiculous to me; after a couple thousand years being Thor, the god of thunder who has had dozens of lifetimes to develop a concrete persona, he becomes a humble man and changes his outlook. It must have been something at that Denny's diner. Probably the pancakes. Or maybe Natalie Portman as Jane Foster is just that hot. (Hint: no.) He probably fell in love with the bars. I have no apathy for New Mexico. Not even people who live there are fond of it! So why would Thor?

Ultimately, if you have the $10 to shell out for a movie, I would say go for it. Did you seen Ironman? The sequel? Yes? Good. Then you will enjoy this, and you will most likely enjoy the upcoming Captain America movie.

Now that is what I am excited about.

Meters used in the MCC panel.

Different types of meters are used in the MCC panel for indicating the status of the panel.Mainly three types of meters are used. Ammeter, Volt meter, Watt meter, Energy meter. Analog and Digital type meters are using nowadays.

Ammeter

Instrument used for measuring the current flow in the circuit is called ammeter. It should be connected series to the circuit .

Analog ammeter

Digital ammeter

Voltmeter

Instrument used for measuring the voltage across in the circuit is called voltmeter. It should be connected paralled to the circuit.

Analog volt meter

Digital volt meter

Wattmeter




Energy meter

This is also called as a watt-hour meter. Energy meter is used for  measurinh the energy consumed in a circuit.

Analog Energy meter

Digital Energy meter.

The wattmeter is an instrument for measuring the electric power (or the supply rate of electrical energy) in watts of any given circuit.

Dangerously Scene.

Or maybe it's called Scout Crossing. I'm still not very sure on the title; it's not perfectly advertised.
Either way, this is a webcomic I just came across the other day. Created by Scott Fergus, the mastermind behind Nerf This and other works, I like to think of it as an alternative-trendy take on the Scott Pilgrim mythos. (Have we decided it has it's own mythos yet? Is there a council to decide that?)

I have always been an admirer of Fergus' art style, and I believe he has discovered the perfect culture to integrate it with.
The story began off a little confusing for me, but soon enough I filled in all of my holes of misunderstanding. It begins with the classic "hiding of the hero" and the typical "call to action" you children learned about in high school English class. Except when Scout is called into action, he begins to punch polar bears and make explosions with his sweet sleeve tattoos.
Yes, magical flower-bomb-tattoos are the source of his power. Which, frankly, is awesome.
I have never been a fan of ink myself, but after only a hour of reading this story I was seriously reconsidering my views.
There are also cute girls, music jokes and a murder mystery.
Stop reading what I'm typing and go read it for yourself. Page one is right here. Dangerously Scene updates once a week; twice if we all are lucky.

Is it just me, or does a female character like this appear in all of his works?

Return of The Venture Bros.

I love this show. 

It's brilliantly written, amazingly hilarious and is a polished parody about a past generation of animated series.
I remember when I was young, I would watch shows like the original Scooby-Doo and shows like Johnny Quest and the various Superhero shows.
Classic Cartoon Network, you know. They were more or less what my parents grew up on; or at least watched ironically.
Then my best friend shared this beauty of a show with me.
It was violent, cruel and held a sarcastic mirror up to that television history.
Mostly I stayed for the violence. Ultimately I fell in love with the theme of the show; failure.
The show is about what happens to our heroes of yesteryear when life throws them a hardball and beats them down. We've all been there.
Part of the original core of comedy is tragedy; we laugh when others fall. Comedy is pretty dark and sadistic if you think about it. At least the good humor is; mom-and-pop humor from the cold war isn't exactly entertaining any more, if it ever was.

I almost came when I heard The Venture Bros. was renewed for a new season.
