Current transformer use precautions

- Oct 05, 2020-

1. Generally speaking, the connection of the current transformer is connected according to the minus polarity, so the polarity connection must be correct. Once the connection is wrong, the measurement will be inaccurate or even short-circuited.

2. In order to prevent the secondary winding from causing high-voltage power to flow into the low-voltage side, causing damage to the instrument and causing personal injury, a protective grounding point should be set.

3. For transformers that use electric energy measurement, if the secondary circuit is implemented, no automatic device is required.https://www.ctsensorducer.com/
