Do the green transformer boxes ever stop working and when the electrical company closes for the day do they shut off the transformer boxes?

No. Transformers remain energised permanently and are only disconnected for maintenance. If the company were to shut off the transformer, then you would lose the electricity supply to your property. An energised transformer normally hums, which is usually an indication that it is energised, however you should ALWAYS assume that a transformer is energised and never interfere with it.

What is the simple device that opens and closes an electrical unit called?
A device that opens and closes a circuit is called a switch.
Make a sentence on working against the clock?
The deadline was set for the next morning; we were really working against the clock.After the restaurant closes, I don't get paid, so I'm really working against the clock to get out of there.The rescue crews are working against the clock, and time is quickly running out for the victims.
Why transformers take high input current at start?
Inrush current is a result of core saturation. The magnetic flux in the core of a transformer is 90 degrees out of phase with the voltage. Ideally the transformer switching device will be closed at a peak voltage, and the transformer core will have no residual flux from the last close. If this occurs, the flux in the core in the first cycle will be no larger than it normally would be. If the switching device closes at a zero voltage, or there is some residual flux, the transformer's core will be driven into partial saturation within the first cycle, unless it has been oversized to prevent saturation. Decreasing the applied voltage at energization will keep this from occuring. One method is to use pre-insertion resistors which cause a voltage drop to the transformer that is significant enough to prevent saturation within the first few cycles, and then they are removed. Another method is to de-engerize the transformer core, and close at voltage peaks only (controlled closing).
What is Inlet valve lag?
it was invented by a man called Justin Andrews . valva lag- inlet valve closes after B.D.C -exhaust valve closes after T.D.C
What is A small piece of plastic-encased metal that closes a circuit?
fuse
It closes the electrical circuit.?
The definition of a switch is a device that closes and opens an electrical circuit.
What a switch does in an electrical circuit?
opens and closes the circuit
Working of a relay?
A small current controls (turns on or off) a large current. Usually performed using a coil to produce a magnetic field which opens/closes an electrical switch.
Electrical device activated by a current that opens or closes another circuit?
An electrical device activated by a current that opens or closes another circuit is called a relay. A contactor also falls into this category.
What does the program 7-Zip do?
It closes Windows when your working on other programs.
What does the program 7 zip do?
It closes Windows when your working on other programs.
Is the key have anything to do with the car starting?
When the key is turned on, it closes an electrical circuit. That closes another electrical circuit which makes and electromagnet work. The electromagnet closes a circuit between the battery and the starter. That starts the car. So the key does not actually do any work to start the car but it tells the various circuits to get busy and start the car.
What is ment by relay?
It is usually an electro-mechanical device where a solenoid opens and closes electrical contacts.
What is work of relay?
A relay is an electrical device that opens or closes in response to a small electrical current or voltage. This makes or breaks the connection in another device.
What is an electrical switch that opens and closes under the control of another electrical circuit?
If it is a physical switch, this is called a "relay" or a "contactor". If it is a semiconductor device, it is typically a triac, SCR or a thyristor.
How relay used for protection purpose?
Relay are operated by small current /voltage connected to Secondary side of Current Transformer and /or Voltage Transformer. The signal stimulates the magnetic substance nearby with the attracting force. This closes or opens the circuit being used in protection purpose.
