Panel Type Fault Indicator

Panel Type Fault Indicator 3 detectors installed on phase and one FI-3PO fault indicator installed on pad-mounted switchgear panel compose this product Busbar outline adopts FI-2B1O as sensor. Cable outline adopts FI-2C1O as sensor.Features:Fault Identification: have the function of short-circuit fault identification, no need to define the actuate current rating. Inrush : Restraineliminate misact phenomenon of closing field-excitation inrush.Reset Mode: by hand or automatic reset. Indication Mode: flash light. Live Line Installing and Removing: detectors can be installed or removed on live line. Rustproof: the structural parts use rustproof material. Inverse Time Limit Operating: maximum suits substation about the protecting operating Characteristic: characteristic, and improve the actuate accuracy rating. Enclosed Electron Switch: send fault signal to FTU by electron switch on/off to implement the supervisory function. Optical Fiber Transfer Signal: isolate primary and secondary connection, and to ensure equipments and personnel safety. Equipement Self-Checking Button: can check inside battery situation of FI-3PO fault indicator momentarily
