ComPass Bs 2.0
Fault direction indicator with monitoring and control function
The ComPass Bs 2.0 is particularly suitable for use in substations with a telecontrol connection for electrical energy distribution in the medium-voltage grid. In addition to the short-circuit and earth fault functions, the ComPass Bs 2.0 collects high-precision measured values for current, voltage and power from the station and makes them available for transmission to the control room. The transformer or station temperature can also be monitored via a PT-100 sensor. Limit values can also be defined for all measured values
, which can also be made available to the control room as alarms.
Voltage coupling/measurement takes place capacitively via the VDI system* and/or via resistive (ohmic) voltage sensors. With simultaneous measurement, the voltage measurement via the VDIS system can be automatically calibrated with the resistive voltage measurement. Up to four ComPass can be connected to a set of resistive voltage sensors.
The ComPass Bs 2.0 also offers a control function for switching two switching elements. A free assignment of six binary inputs, which can be combined with freely programmable logic (PLC functionality), allows the user to flexibly define switching conditions. The binary inputs can also be used to record any information, e.g. SF6 gas fault or HV fuse failure.
* VDIS according to IEC62271-213, current standard as of 08/2023
