Switch unit description Recloser principle Reclosersareusedinoverheadlinesandinsubstations.Likecircuit-breakers theyarecapableofswitchingnormalandfaultcurrents.Theyareequipped withsensorsandcontrollerbeingtheprotectionandcontroldevice.Incase of a temporary line fault, they can trip and reclose up to four times, thus avoidinglongernetworkinterruptions. Recloser cycle Incaseofanetworkfault,therecloseropensandreclosesseveraltimes.In case of temporary faults, the automatic reclosing significantly reduces the outage times. While the trip settings for each operation can be set individually....

Controller description TheMicroprocessorBasedcontroller FTU-R200provideprotection,control, instrumentation and metering with integrated input and output logic, data logging&faultreports. Communication access to controller functionality is via electrical RS485 port for remote connection. Additional rear port options including RS232 port is available. Thecontrollerismountedinthecontrolcubicle.Alongwiththecontroller,this cubicle also contains the auxiliary power supply with batteries for uninterruptiblepowersupply,electronicboardsandcircuitbreakers. The controller contains a large number of...
