VisiVolt Passive Voltage Indicators
VisiVolt™ – Passive Voltage Indicator is a busbar-mounted-type indicator of voltage presence developed to be used in outdoor and indoor systems, 3-36 kV.
The VisiVolt can be easily and permanently installed on busbars and naked or insulated metal conductors in medium voltage systems. VisiVolt indicates the presence of voltage by displaying a large, well visible lightning arrow sign on its LCD.
The VisiVolt silicone elastomer enclosure ensures performance in outdoor conditions while its fluorescent orange color provides good visibility among the other elements of the system.
