Application
As tools for linework, these two Digital Voltage Indicators (DVI) apply to most system voltages. The Distribution DVI provides 1 to 40 kV readouts; and the Transmission DVI covers 16 to 161 kV. For overhead applications, the hooked probe hangs directly onto the conductor or apparatus. For underground systems, the Distribution DVI can indicate voltage at elbow test points or through bushings and elbows.
For such uses as confirming a “dead” condition before placing temporary grounds for de-energized maintenance, both models provide an easy, yet reliable, means to determine if a line is:
• De-energized…
• Carrying less than normal system voltage from any source or induced charges from an adjacent live circuit…
• Energized at full system voltage.
Special Design Features
Simply by selecting “Peak Hold,” the DVI will retain the display of its approximate highest reading for 10-15 seconds.
A built-in self-test function allows for a quick check of the meter before and after each use.
