The KD1E/33 is a neon HV potential indicator suitable for use on earthed neutral systems up to 33kV. A range of highly portable, neon and digital potential indicators, these instruments provide a means of confirming the presence of voltage on earthed neutral electrical circuits.

Conforming in design lengths to recommended creepage and safety standards, the KDIE series features high grade PVC tubing and incorporates totally encapsulated resistor chains. For additional safety a proving unit (PH3) is available and should be used before and after the high voltage indicator is employed.
