IPS2, IPC4010 and IPC4012 are all three combined earth fault and over current detectors from Protrol. They are based on Protrol’s well proven method for directional detection of earth faults, also intermittent faults. The patented algorithm performs three phase current measurements but does not require any voltage measurement which results in a cost efficient solution.
IPS2 is suitable for basic fault detection functionality while IPC4010 and IPC4012 are possible to use for more advanced autoreclose systems. The fault detector IPC4010 is communicating via RS485 interface and supports standard protocol IEC60870-5-101 while IPC4012 offers Ethernet together with IEC60870-5-104 protocol.
