PRODUCT INFORMATION
EARTH-FAULT indicator
TypE VN-E
The earth-fault indicator can be used in radial medium voltage networks with one input and open-ring networks. The network has to be solidly earthed or low resistance-earthed. The indication unit is directly mounted on the 3-core-cable with cable ties. The indication of the earth-fault is done by an LED indicator. The earth-fault sensor measures the sum current of the three conductors. The indicator is divisible. Therefore the short-circuit indicator can
be retrofitted on the cable.
The earth-fault indicator type VN-E consists of one sensor with integrated indication.
It is powered by an exchangeable lithium battery.
