The reason why the Electrical Current Transformer will be burned during use

There are many reasons for the electrical current transformer to burn, the common reasons are as follows. The Electrical Current Transformer opens twice, creating a high voltage that burns the Electrical Current Transformer. If the insulation aging time is too long, local breakdown or discharge will result in overvoltage, which will cause the Electrical Current Transformer to burn out. Once the Electrical Current Transformer is connected to aluminum, the contact surface of the row is severely oxidized, the contact resistance is too large, and the Electrical Current Transformer is thermally burned. When the user is overloaded for a long time, the Electrical Current Transformer will burn due to heat.

How to avoid Electrical Current Transformer burning? Install circuit breakers first to avoid branch failures affecting the entire line, especially to ensure that branch circuit breakers can trip reliably. The Electrical Current Transformer is then attached to the back of the circuit breaker to ensure proper operation of the circuit breaker and arrester to eliminate faults in the event of a transformer failure. It is also necessary to strengthen the high-voltage insulation test of the user's Electrical Current Transformer and arrester, find out the insulation aging degree of the transformer and the arrester as soon as possible, and replace it in time to avoid the occurrence of power failure. Caused by a burnout of the transformer, then regular cleaning of user equipment is also required to reduce contamination and avoid insulation degradation.

When using the Electrical Current Transformer, please carefully check whether the secondary circuit is disconnected, whether the contact resistance is too large, and be sure not to overload. In addition, the Electrical Current Transformer must be maintained and maintained. If aging insulation is found, it should be replaced in time and cleaned regularly to reduce pollution. Only in this way can the Electrical Current Transformer be used stably and with a longer service life.
