It is an instrument used to change voltage. The purpose of changing voltage is mainly to supply power to measuring instruments and relay protection devices, to measure the voltage, power and electric energy of lines, or to protect valuable equipment, motors and transformers in lines when lines fail. Therefore, the capacity of voltage transformers is very small, generally only a few volt amperes, tens of volt amperes, and at most one-thousand-volt amperes.

Transformer oil level gauge is suitable for oil-immersed transformers, which is installed in the upper part of the transformer oil tank, showing the oil level in the oil tank. When the blue mark appears in the window of the upper part of the oil level, the oil level is normal, and the oil level is below the tank cover; when the red mark appears, the oil level is abnormal, and the oil level is below the tank cover, so it is necessary to replenish oil properly. The top is equipped with a pressure release valve. When the pressure in the oil tank rises to the opening pressure of the release valve, the release valve opens quickly to release the pressure to prevent danger.

Transformer bushing is an insulating bushing that leads the high and low voltage leads inside the transformer to the outside of the oil tank. It not only insulates the leads to the ground, but also plays a role in fixing the leads. Transformer bushing is one of the current-carrying elements of the transformer. During the operation of the transformer, the load current passes through for a long time, and when a short circuit occurs outside the transformer, the short-circuit current passes through.
