FDR-115 series intelligent feeder terminal unit (FTU) is a new type terminal unit which Zhuhai XJ Co., Ltd. develop for adapt smart distribution network development , integrated fault handling , measurement & control .Cooperate with overhead distribution switches , applied to sections (branches) or loop point of mid-voltage overhead distribution lines .FTU designed from new-generation platform , integrated communications , measurement , remote control , local fault detection , device status management and other functions.

Especially , it can use voltage-time strategies realize local isolate fault rapidly and restored power of non-fault zone , report fault information to background system or operators to narrow the blackout zone and reduce the pressure of operator.
