ComPass D
Fault direction indicator with monitoring and control function via Ethernet
The ComPass D is particularly suitable for use in central substations in the medium-voltage grid that have a telecontrol connection. In addition to the short-circuit and earth fault functions, the ComPass D collects high-precision measured values for current, voltage and power from the station and makes them available for transmission to the control room.
A PT-100 sensor can also be used to monitor the transformer or station temperature, for example. Limit values can also be defined for all measured values, which can also be provided as alarms for the control room. Voltage coupling/measurement takes place capacitively via the VDIS system* and/or via resistive (ohmic) voltage sensors.
With simultaneous measurement, the voltage measurement can be automatically calibrated with the resistive voltage measurement via the VDIS system. Up to five ComPass can be connected to a set of resistive voltage sensors.
* VDIS according to IEC62271-213, current standard as of 08/2023
