本系列电流互感器适用于户内， 额定频率50Hz或60Hz， 额定电压35kV及以下的小接地电流系统中供三相电缆接地保护用， 也可与继电器配套使用。
安装时可将互感器分为两半， 然后合并为一体， 用抱箍抱紧卡住， 可以在不停电状态下进行安装。

This series of current transformers is 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 relay.
The transformer can be divided into two parts during installation, and then they can be combined again and buckled tightly with clamp. It can be installed without power off.
