How to avoid burnout of current transformer

- Aug 24, 2020-

First, equip the current transformer with a circuit breaker, so that the entire line will not have a power outage, and the branch fault wave will not have a power outage. The most important thing is to ensure that the branch circuit breaker can safely trip.

Then connect the current transformer behind the circuit breaker. The purpose of this is that when the current transformer fails, the circuit breaker can make a correct response to remove the fault. Carry out high-voltage insulation test on the current transformer, so as to find out to what extent the insulation aging of the current transformer has reached as soon as possible. Cause power outages.
