Installation and precautions of zero sequence current transformer 　　 The symbol of zero-sequence current transformer Zero-sequence current transformer is a kind of current transformer, used to detect neutral unbalanced current, generally used in cooperation with relay...

There are many reasons for the burning of the current transformer 　　 1. Install circuit breakers to prevent branch faults from power outages of the entire line, especially to ensure that the branch circuit breakers can reliably trip. 　　2. Connect the current...

　　 Current transformers with “S” and without S both indicate the accuracy level of the measurement current transformer. Under the conditions of regular use, the error of the transformer is within the limit of the rule of this level. The commonly used...

　　Open-close current transformer is often used in equipment. It has a good induction effect, can improve the operation efficiency of the equipment, has a good effect in controlling current, and completes up and down voltage conversion. In order to make it work...

　　 (1) No open circuit is allowed on the secondary side of the current transformer. The secondary open circuit may produce serious results. One is that the iron core is overheated and even the transformer is burned; the other is that the number of turns of the...

　　 It is necessary to study the working characteristics of the zero-sequence current transformer, and confirm whether it can saturate and affect the correctness of the maintenance action when the external fault passes through a large current during maintenance. It can...
