The general concept of current transformers

A general current transformer can transform a primary current with a large value into a secondary current with a smaller value according to a certain transformation ratio, so as to play the main purpose of maintenance and accurate measurement. The main function of the zero-sequence current transformer is to protect the power circuit when an…

Voltage transformers and current transformers

In order to accurately measure the power consumption in high-voltage and high-current AC circuits, voltage transformers and current transformers are generally used to convert high voltage into low voltage and large current into small current, and configure a moderate meter to use voltage Transformers to carry out accurate measurements. For example, the current, working voltage,…
