EARTH 4.0

The EARTH 4.0 device is an earth fault indicator. It is designed to detect, locally indicate and remotely report earth fault currents in medium voltage distribution networks.

Earth Fault Indicator

Product Features

  • Indication of earth fault currents by LED and mechanical flag

  • Remote indication via relay contacts

  • Battery status indication and remote indication via relay contact

The EARTH 4.0 device is an earth fault indicator. It is designed to detect, locally indicate and remotely report earth fault currents in medium voltage distribution networks. A wired earth fault current transformer monitors the summation current of all three conductors. The electronics of the display unit evaluates the measurements. When the fault sensitivity threshold is exceeded, a red LED will start flashing and a mechanical flag become visible. In addition to that, the remote indication contacts are energized. A system-specific external signal lamp is optionally available.
