There are many reasons for the burning of the current transformer

　　 1. Install circuit breakers to prevent branch faults from power outages of the entire line, especially to ensure that the branch circuit breakers can reliably trip.

　　2. Connect the current transformer to the back of the circuit breaker to ensure that the circuit breaker and arrester act correctly when the transformer fails to remove the fault.

　　3. Strengthen the user’s current transformer and arrester high-voltage insulation experiment, find the insulation aging degree of the transformer and arrester as soon as possible, and replace it in time to prevent the transformer from burning out and causing a power outage.

　　4. In addition, it is necessary to clean the user’s equipment on time to reduce pollution and prevent insulation degradation.
