General

This series of current transformers are used in indoor small ground current systems with rated frequency 50Hz or 60Hz and rated voltage up to and including 35kV for three-phase cable grounding protection, it also can be used with a relay.
The transformer can be divided into two parts during installation, and then can be combined again and buckled tightly with a clamp. It can be installed without power off.
