Analysis of the basic knowledge of these two current transformers and the difference between the two
Aug 12 , 2021
1. Bus-type current transformer and pillar-type current transformer Transformer I was asked a question by someone the day before, what is the difference between a bus-type current transformer and a pillar-type current transformer? At that time, there was some confusion, let alone the difference. I still don't have any idea what these two forms look like. After checking the materials, I found that ...

The benefits of correct wiring of current transformers for short circuit inspection
Aug 12 , 2021
The wiring method of the current transformer is not very complicated, there are only four wiring forms. The four types of wiring will be listed below. Transformer 1. The first is the wiring method of a single current transformer. Under the condition of only single-phase current, it is suitable to measure one-phase current or three-phase load balance, and the three-phase status can be understood by...
