Things to keep in mind when using Electrical Current Transformer

First of all, you must ensure that the polarity connection of the Electrical Current Transformer is correct, otherwise the measurement will be affected, especially when multiple Electrical Current Transformers are connected in parallel, the wrong connection will also cause a short circuit. Secondly, the secondary circuit in the Electrical Current Transformer should be equipped with a protective ground to fully ensure safety, but only one is allowed.

When the Electrical Current Transformer is in the running state, the secondary winding is not allowed to open circuit, otherwise it will not only increase the error, but also endanger the safety. In order to ensure the safety of the secondary circuit of the Electrical Current Transformer, some people will connect relay protection devices and automatic devices, but in fact this approach is inappropriate and will affect each other.
