Product Description
This fault indicator ComPass Bs 2.0 from HORSTMANN is designed for use in medium-voltage substations with remote control connection. The ComPass Bs 2.0 detects short circuits and earth faults and collects measurement data for current, voltage, and power for transmission to the control room. The device can also monitor transformer or substation temperature via a PT-100 sensor and supports definable limit value alarms.Technical Features
- Short-circuit and earth fault indication, as well as earth fault localization.
- Measurement of current, voltage, and power with specified measurement accuracy up to 0.5%.
- Temperature monitoring via PT-100 sensor and the possibility of alarms at limit values.
- Voltage measurement capacitively via VDIS (according to IEC62271-213) and/or via resistive (ohmic) voltage sensors; automatic calibration between VDIS and resistive measurements when measuring simultaneously.
- Up to four ComPass units can be connected to one set of resistive voltage sensors.
- Two contact outputs (switching elements) for remote control and six binary inputs with freely programmable logic (PLC functionality).
- Local indication via two directional arrow LEDs (A, B) and high-contrast OLED display; front USB port and mini-USB for commissioning and parameterization with ComPass Explorer software.
Typical Applications
The ComPass Bs 2.0 is used in medium-voltage substations with remote control connection for:- indication of short circuits and earth faults, including direction,
- collection and transmission of measured values (current, voltage, power) to the control room,
- local monitoring of transformer or substation temperature via PT-100 and alarm output when defined limit values are exceeded.
