What Are The Methods For Checking Transformers With Line Fittings?

Insulation Piercing Connector What are the methods for checking the transformer?

1. Check the actual wiring and transformation ratio of the transformer, check the wiring and transformation ratio of the voltage transformer, check the wiring and transformation ratio of the current transformer. For multi-ratio current transformers, the transformation ratio can be changed by changing the number of turns on the primary side.

2. Check the operation of the transformer, observe whether there is a broken wire or overheating on the surface, and the sound is very normal. There will be an obvious buzzing sound when the current transformer is open. After the power outage, check the voltage, current transformer, and voltage transformer immediately. If the voltage transformer is overloaded or the current transformer is open, touch it with your hand and feel hot. When the voltage transformer is open, the hand temperature will be significantly lower than the normal value. The internal fault of the voltage and current transformer will cause overheating, and there will be a smell of the insulating material volatilizing when it is heated.
