Digital Voltage Indicators

The DVI-100 Series Digital Voltage Indicators are single point instruments designed to read the voltage on a conductor up to 99kV 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.

There are two DVI-100 models. The DVI-100 indicates voltage from 0.1kV to 99kV on overhead and underground systems - displaying the voltage on a large 2-digit LED display. The DVI-100T with Test Point Mode has the added feature of indicating voltage on elbow test points.

The DVI displays the voltage and emits an audible alarm when voltage above 100VAC is detected with no range selector switches or settings to be made - just contact the conductor and read the display. This allows the user to determine if the voltage being read is nominal or a lower induced voltage.

For higher voltages, the DVI-500 Series Digital Voltage Indicators indicate voltage up to 500kV on a three-digit display.  Click here to visit the DVI-500 Series webpage.
