Fault Detector With Build-in RTU IPC4020 is a fault detector for overcurrent and earth faults with integrated remote terminal unit functionality. It has I/O for indications and orders and is therefore suitable for a typical secondary substation with up to four objects. The standard IPC4020 detects faults on one feeder. It can be ordered with an expansion module that allows fault detection of 2 additional feeders.
Fault indication with LED (LED unit is included). After power disruption the detector signals with a red flash for pass-through faults and green if no fault current has passed. The LED unit, locatated at the outside of the secondary substation, is activated when the substation becomes unenergized.
Fault indicator with two configurable closing contacts, function specified at order, see datasheet. Overcurrent and earth fault detection with multiple levels. Operate time configurable. Two binära inputs. IEC60870-5-101 via RS485 (option, see datasheet). Power supply 24 - 48 VDC.
