Switch-ComPass Bs 2.0

The new ComPass with control function and freely programmable logic

Directional Short-Circuit and Directional Earth Fault Indicator with monitoring and control function

Product Features

  • For remote controlling of a load-break switch or circuit-breaker
  • Free assignment of 6 binary inputs for the collection and transmission of relevant switchgear/station data
  • Freely programmable logic for flexible definition of switchgear conditions
  • Directional short-circuit and directional earth fault indicator
  • Clear fault indication and reading on-site: 2 directional arrow LEDs (A, B) and high contrast OLED display
  • Monitoring of the parameters voltage (V), current (I), load flow
    direction (B↓ or A↑), power factor (cos φ), power (P, Q, S), energy (E), tem-perature (T) and frequency (f)
  • Suitable for all types of networks/neutral point treatments
  • Earth fault detection with 6 different earth fault detection methods, also in combination
  • High-precision current and voltage measurement to 0.5 %
  • Voltage monitoring with connection to capacitive and resistive (ohmic) sensors in one indicator
  • PT-100 temperature sensor for equipment monitoring
  • Limit monitoring: V, I, P, Q, T
  • ComPass Explorer Software: Commissioning and parametrisation via front accessible USB port

The Control ComPass Bs 2.0 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 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 PT100 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 or via resistive (ohmic) voltage sensors. Up to four ComPass can be connected to one set of resistive voltage sensors.
In addition to the functions of the ComPass B 2.0, the Control ComPass Bs 2.0 offers a control function for switching a load-break switch or circuit-breaker. A free assignment of 6 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.

Equipment set:

1 Display unit
3 single-phase current sensors
or 2 single and 1 summation current sensor
