1. Install circuit breakers to prevent branch failures from affecting the entire line power outage, especially to ensure that 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 surge arrester operate correctly to remove the fault when the transformer fails.
3. Strengthen the high-voltage insulation test of current transformers and surge arresters of users, find the degree of insulation aging of transformers and surge arresters as soon as possible, and replace them in time to avoid the occurrence of power outages caused by transformer burnout.
4. The other is to clean the user's equipment regularly to reduce pollution and avoid lowering insulation.
