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 of 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.

Product features:
- Remote control option for 2 switching elements
- Communication via Ethernet with IEC 60870-5-104 protocol
- Clear error display and reading option on site:
2 directional arrow LEDs (A, B) and high-contrast OLED display
- Highly accurate current and voltage measurement with 0.5 %
- Monitoring of the variables voltage (U), current (I), load flow direction (A↑ or B↓ )
- Power factor (cos φ), power (P, Q, S), energy (E), temperature (T) and frequency (f)
- Suitable for all mesh types/star point treatments
- Earth fault detection with six different earth fault location methods, can also be combined
- Voltage coupling to capacitive and resistive (ohmic) sensors
- Limit value monitoring and remote signalling: U, I, P, Q, T
- Commissioning via USB connection with support for the ComPass Explorer and ScadaData configurator software
- Freely assignable binary inputs for recording and transmitting relevant status information from the system/station
- Freely programmable logic for defining the switching conditions

Added value:
- Fast error direction detection
- Highly accurate current and voltage monitoring
- Detection of limit violations
- Availability of measured values in the control room and on site
- Can be controlled remotely from the control room using the IEC 60870-5-104 protocol
- Automatic self-calibration of the capacitive voltage inputs, optionally with temperature compensation
