How to prevent the current transformer from burning out?

First, install a circuit breaker to prevent branch faults from affecting the entire line to blackout, especially to ensure that the branch circuit breaker can reliably trip. Then connect the current transformer to the back of the circuit breaker to ensure that the circuit breaker and lightning arrester operate correctly to remove the fault when the transformer fails. It is also necessary to strengthen the high-voltage insulation test of the user's current transformer and arrester, to detect the aging degree of the insulation of the transformer and arrester early, and replace it in time to avoid the occurrence of power outages caused by burnout of the transformer. The last thing is to regularly clean the user's primary equipment to reduce pollution and avoid insulation degradation.
When using the current transformer, carefully check whether the secondary circuit is open, whether the contact resistance is too large, and the most important thing is that it cannot be overloaded. In addition, it is necessary to maintain and maintain the current transformer. If the insulation is found to be aging, it must be replaced in time, and it must be cleaned regularly to reduce pollution. Only in this way can the current transformer be used safer and have a longer service life.
