Capacitive voltage indicators are used for detecting potential on bus bars off medium-voltage cubicles. The capacitive voltage indicators are produced in three types: EVD, EVD-RX and EVI-3L.
Capacitive voltage indicators work together with capacitive dividers in medium voltage cubicles. Voltage indicators are compatible with IEC 61243 standarts and separated for each phase. Accordingly; Un > Un there is potential in the bus bar and the leds are flashing. Un < Un there is no potential in the bus bar and the leds are not flashing.
