How do you measure the capacitance of 3 phase capacitor in active line voltage of 3 phase circuit?
You measure the capacitance of a capacitor in an active circuit by observing the voltage across it and the current through it. That gives you, by Ohm's law, the impedance of the capacitor. Plug that in the the equation for capacitive reactance, and you get capacitance. Note: There is no such thing as a three phase capacitor. A capacitor is a two terminal device that resists a change in voltage inversely proportional to its capacitance. You connect one capacitor to one phase. If you have a "three phase capacitor", then you are talking about three capacitors. Deal with each one separately.
Capacity of transformer is 1600 kva.11kv system. in our company y phase continuosly taking high loads then R phase and B phase .due to that y phase cables in capacitor bank and mcc panels opencircuiti?
If one of the phases continuously takes a high load with a poor power factor it might have tripped a circuit breaker in the capacitor bank.
Why does a single phase synchronous motor need a capacitor but for a three phase motor it is not required?
A three-phase motor has a rotating magnetic field inside that is set up by the supply, so the armature always rotates in the correct direction. A single-phase motor can in principle start either way so it has a starting winding supplied through a capacitor to provide a small component of rotating field to get it started the right way. After it has picked up speed the starting winding can be switched out.

What is run capacitor in single phase motor starter with three wire?
A run capacitor and a starter capacitor are not the same thing. A run capacitor is energized the entire time the motor is running, and a start capacitor is not. A run capacitor is one that changes the current on the windings of a single phase AC induction motor to create a rotating magnetic field to energize a second-phase winding. A start capacitor increases starting torque, allowing a motor to be turned on rapidly. It stays in the circuit only long enough to bring the motor to 3/4 of full speed. Some motors then continue to run with a run capacitor.
How can you use a 3 phase capacitor as a single phase capacitor?
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
How do you wire a three phase motor with capacitor start?
I have never come across a three phase capacitor start motor. Any three phase motors I have worked on are induction start.

Why capacitors are not used in three phase motor?
There is no need. The three-phase supply provides a rotating field in the motor, rotating in the right direction, so there is no need for a starting capacitor.

How to connect 3 phase power factor correction capacitor?
how to connect power capacitor with 3 phase motor
Are any capacitor in three phase induction motor?
There doesn't have to be but capacitors are sometimes used to correct the power factor.
What is this system called with three single phase transformer?
Your question is rather vague. If you are asking what do you call a group of single-phase transformers, connected to supply three phase, then the answer is a 'three-phase transformer bank'.

Function of switched capacitor for three phase power generation from single phase?
usually they say its possible 2 convert a 2phase supply to 3 phase.if its so then how?
