ComPass A 2.0

Short-circuit and earth fault indicator

OLED display: easy to read in all lighting conditions
Displaying the measured values and configuring via the display
Rocker switch for easy handling
Easy parameter setting and commissioning via USB port
Reverse polarity protected plug-in terminals for quick and easy installation

Description

The ComPass A 2.0 is suitable for use in substations with a remote control connection of the electrical power distribution in a medium voltage network. Trip current values and pre-fault current values are logged with time stamp.

In addition to the short-circuit and earth fault function, the ComPass A 2.0 measures the temperature, for example of a transformer or the transformer station with the PT100 sensor.

The ComPass A 2.0 provides the collected information, measured values and their limits, for transmission to the control room. Phase selectivity and faults (earth fault or short-circuit) are also shown in the OLED display.

Equipment set includes:

1 display unit
3 single-phase current sensors
