New expandable fault detector

IPC4020 is our newest fault detector for overcurrent and earth faults with integrated remote terminal unit functionality.

The basic version is designed for a typical secondary substation with up to four objects. It can also be ordered with expansion. With expansion it can perform fault detection of three separate objects.

Since the algorithm for earth fault detection does not require any voltage measurement, IPC4020 provides very cost-efficient fault detection and grid automation with a high sensitivity for pass-through faults, also in networks where the earth fault currents are low.
