Voltage detectors

Comet BK-I

Short version, for dry conditions

The Comet BK-I / BK-A devices are capacitive voltage detectors for testing the voltage on one pole in short version. They are intended for the detection of operating voltages clearly indicating either the “voltage present” or “voltage not present”state.

The voltage detectors are provided with a built-in self-test facility which checks the function of the circuit including the contact electrode (comprehensive self-test function) before each use.

For transportation purposes, the insulating element can be removed from the display with the contact electrode.

According to the German accident prevention standard DGUV Regulation 3 (Table 1c), the device is subject to maintenance tests with minimum intervals of at least 6 years.
