Can a leakage protector be used in the application of electrical transformers? Many people may not be aware of this. Below, the editor from Jiangsu Jula will provide a detailed introduction for you.
Leakage protection devices are designed to provide safety for humans in the event of electrical leakage risks in distribution machinery and equipment, as well as offering load and overvoltage protection. So, can leakage protection devices be used in electrical transformers? Can they serve a purpose during the application of transformers?
On this issue of concern, the electrical transformer manufacturer explicitly states that it is crucial for everyone to take great notice. In the ordinary use of electrical transformers, the leakage protector should not be applied. Why? It is emphasized here that under the use of electrical transformers, the leakage protector must never be used, as this is a major rule in transformer application. The reason is that the mechanism of the leakage protector actually requires a zero-sequence current of zero. In the context of transformer use, a zero-sequence current is unlikely to be zero.
Additionally, due to the PWM waveform output from the power transformer, a capacitive effect is induced between the motor cable and the ground, especially when shielded cable layers are used. This capacitive effect is more pronounced. Therefore, during the operation of the power transformer, when capacitors are charging from the battery, current can flow through the capacitors to the ground and then back to the transformer through the incoming wire connections, thus creating a current control loop.
Therefore, under the application of electrical transformers, leakage protection devices should not be used; simply ensuring the grounding process for the machinery and equipment is sufficient. Remember, do not equip your electrical transformers with leakage protection devices.
When selecting and applying electrical transformers, it is crucial to seek out a technically proficient manufacturer of electrical transformers or to make selections and applications under the guidance of professionals. Do not attempt to make decisions independently to prevent accidents.
