what is the difference between potential Transformers and
capacitive voltage transfoemers and where it is used?

Answer Posted / amit khamesra

The purpose of VT and CVT in EHV system is same ie. to step
down the EHV to low voltage for measurement and protection
purpose. The extra function which CVT performs is to trap
the high voltage signals from the line which are used for
PLCC communication.

why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating.
