HD Electric Company's Digital Voltage Indicators (DVI) are single point instruments designed to read the voltage on a conductor up to 500kV line-to-ground. The large LED readout is easy-to-read on the end of a long hotstick and can be used on overhead lines or in underground applications with an underground bushing probe.
The DVI emit an audible alarm when voltage above 100VAC is detected. They are very easy to use as there are no range selector switches or settings to be made - just contact the conductor and read the display.
There are four DVI versions. The NEW DVI-500 models indicate voltage from 0.1kV to 500kV on overhead and underground systems - displaying the voltage on a large 3-digit LED display. The DVI-100 models indicate voltage from 0.1kV to 99kV on overhead and underground systems - displaying the voltage on a large 2-digit LED display.
