Capacitive Voltage Indicators

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 > %45 Un there is potential in the bus bar and the leds are flashing. Un < %10 Un there is no potential in the bus bar and the leds are not flashing.

Features:
Wide operation range (1kV-52kV)
Adjustable operation voltage (in EVI-3L type)
Three LED for each phase (in EVD and EVD-RX types)
LCD indicator with three steps (in EVI-3L type)
Test point (Three phase - ground)
LRM Interface (in EVI-3L type)
Compatible with IEC 61243-5 standards
Energy Alert Relay (in EVD-RX and EVI-3L types)
