Please what happens when you create a contact relationship between voltage of different phase angle..like a short circuit

 

You usually get a big spark.

 

If this is done at a power generting station one of the generators will fly from its mounts.

 

It's called "trip the circuit breaker".

how?

 

Electromagnetism.

(or magical electrical pixies. depending on your belief systems.)

 

Confused nw..magic pixies, circuit breakers..#giveup

 

A short circuit doesn't have a phase angle. If one voltage meets another voltage with a different phase angle......the result can be much worse than a short circuit. It can be double worse.

It all depends on the angles.

You can see this in an intense manner when putting a generator on line.

The phase difference will be equal to the number of degrees the generator rotor shaft will try to rotate....instantly....when you flip the switch....so be careful.

This can turn a generator into a spherical ball of high velocity shrapnel.

Yeah..woudnt even try that..

The old method of getting the generators in phase was quite simple. (I remember seeing it done in an old black and white movie).

The were light bulbs connected between matching phases of two generators -- before connecting the generators together. The 3 bulbs were arranged as a triangle. When the off-line generator was running at nearly the same frequency as the power grid generators the bulbs would display a rotating pattern. When the bulbs rotated very slowly and then all of them were dark the generators were in phase. It was then safe to throw the switches that tied the generators together.
