SPRECON-E-P ERER3

Article: 00086658

Electronic relay / protection / ground fault / panel-mount

In power grids without earthed neutral points, the ERER3 relay is used for directional earth fault detection with transient evaluation.

These analogue-electronic transient relays signals earth faults together with the respective direction via LED and relay outputs. The signalled directions can be registered by digital protection devices via binary inputs. The SPRECON-E D..6 devices import these measured-values into the power control system. In comparison with older harware versions, the current ERER3 relays supports higher accuracy for high-resistance earth faults.
