HV Voltage Indicator Proving Unit Kit Calibration


HV Voltage indicators are devices for measuring alternating current (AC) voltages. HV Voltage indicators continuously show the present voltage via a light or precisely on a built-in LED display. HV Voltage indicators check the voltage of HV transformers, live rails and HV busbars.

HV Voltage indicators are also known as Potential Indicators.

Voltage Proving Units are used to prove whether your detectors and HV voltage indicators are working correctly, they are suitable to Prove the functional operation of the HV Indicator.

Battery-powered Voltage Proving Units are intended to be lightweight and compact devices for ensuring safe operation when working with electricity. They serve as a verification step to safely work with high or even low voltages. During installation procedures, they should be utilised regularly (not just with unfamiliar/new equipment).
