本系列電流互感器適用于戶內(nèi)， 額定頻率50Hz或60Hz， 額定電壓35kV及以下的小接地電流系統(tǒng)中供三相電纜接地保護用， 也可與繼電器配套使用。
安裝時可將互感器分為兩半， 然后合并為一體， 用抱箍抱緊卡住， 可以在不停電狀態(tài)下進行安裝。

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.
