Digital Voltage Indicators

The Digital Voltage Indicator (DVI) is a single point instrument 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 versions of the DVI-100 series. The DVI-100 indicates voltage by directly contacting conductors on overhead and underground systems. The DVI-100T with Test Point Mode also indicates voltage on elbow test points.

When brought into direct contact with a conductor while mounted on a hotstick, the two-digit display indicates the line-to-ground voltage level. The instrument is auto-ranging and indicates voltages from 0.1kV to 99kV. This allows the user to read the voltage and also determine if it is at nominal voltage or a lower induced voltage. The DVI emits an audible alarm when any amount of voltage is detected.

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.
