Precautions for the use of Electrical Current Transformer
Jul 12, 2021| 1. Regarding the transformer that uses electric energy measurement, if the secondary circuit is implemented, there is no need for an automatic device.
2. In order to prevent the secondary winding from causing high-voltage power to penetrate into the low-voltage side and cause damage to the exterior and cause personal injury, a maintenance grounding point should be set.
3. Generally speaking, the electrical current transformer is connected in accordance with the reduced polarity, so the polarity connection must be correct. Once the connection is wrong, the measurement will be inaccurate and even short-circuited.
