1.Product Description
The zero-sequence current transformers(cables types) with the diameter of 80-300 include various high-precision zero-sequence current transformers different in capacity , ratio and accuracy limit factor, as well as other high-precision zero-sequence current transformers matching with small current grounding line selection devixes and relays, which can be classified as integral types and modular- based products.
