ComPass D

Directional fault indicator with monitoring and control function via Ethernet

The ComPass D is suitable for use in substations with a remote control connection of the electrical power distribution in a medium-voltage network. In addition to the short-circuit and earth fault functions, the ComPass D collects highly accurate measured values for current, voltage and power from the substation and makes them available for transmission to the control room. The PT-100 sensor measures the temperature, for example of the transformer or the transformer station. For all measured values limits can be defined, which can also be transmitted to the control room.

The voltage coupling/measurement is done via the capacitive VDIS* system and/or via resistive (ohmic) voltage sensors. Up to five ComPass D can be connected to a set of resistive voltage sensors.

The ComPass D offers a control function for switching a load-break switch or circuit-breaker. A free assignment of six binary inputs in combination with a freely programmable logic (PLC functionality) enables the user to define the switching conditions in a flexible manner. Random information, such as the SF6 gas disruption or HV tripped fuse, can be captured via the binary inputs.

* VDIS according to IEC62271-213, current standard as of 08/2023
