Voltage indicator Comet BL-I 10-20kV optical

Description

The Comet BL-I / BL-A devices are single-pole capacitive voltage detectors. 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.
