12kv Open type current transformer

Special specifications or high-precision products can be made according to user needs. The current transformer can only use one of the changes during use, and several ratios cannot be used at the same time.

General:

This type of current transformer is a new patented product specially developed by our company for the intelligent and lightweight power system. It is small in size and light in weight, and the combination is very reasonable. realizable A, B, C three-phase protection and zero sequence grounding protection.
