ComPass D — Fault direction indicator with Ethernet monitoring
The ComPass D from HORSTMANN is a fault direction indicator with monitoring and control functions via Ethernet. The device is designed to deliver precise measurements of current, voltage, and power to the control room and provides local indication of fault direction via two directional arrows and a high-contrast OLED display.
Features and measured data
- Measurement precision up to 0.5%.
- Recorded measurements: conductor currents, phase-to-ground and phase-to-phase voltages, power (P, Q, S), energy, temperature, and frequency.
- Ground fault detection via six different methods (can be combined).
- Voltage coupling/measurement: capacitively via the VDIS system and/or via resistive (ohmic) voltage sensors; up to five ComPass units can be connected to one set of resistive voltage sensors.
- Support for external temperature measurement via PT100.
- Freely assignable binary inputs and freely programmable logic for control conditions.
- Mini-USB port for parameterization and commissioning with ComPass Explorer and ScadaData configurator.
Communication and control
Communication takes place via Ethernet with support for the IEC 60870-5-104 protocol, enabling the transfer of measured values and alarm messages to the control room. The device offers remote control of two switching elements and local readout via an OLED display and two directional arrows (A, B).
Additional technical information and product details can be found in the manufacturer's documentation: See manufacturer's product page.
Typical applications
The ComPass D is intended for use in central medium-voltage substations with telecontrol connection, where fault detection, directional indication, and transmission of precise measured values to the control room are required.
