ComPass Bs 2.0
The ComPass Bs 2.0 is particularly suitable for use in those substations in a medium voltage network that feature a remote control connection. In addition to the short-circuit and earth fault function, ComPass B 2.0 supplies the collected measured values of current, voltage and power from the station 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 VDS system and/or via resistive (ohmic) voltage sensors. With the simultaneous measurement, the voltage measurement of the VDS system can be automatically calibrated with the resistive voltage measurement. Up to four ComPass B can be connected to one set of resistive voltage sensors.
In addition he 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.
