The Swedish Neutral Earth Fault Locator detects earth faults in resonance and other high impedance grounded high voltage networks. The Earth Fault Locator supplies information on what feeder the earth fault has occurred (feeder indication).
If the network structure allows for looping of feeders the Earth Fault Locator can provide, in addition to feeder indication, distance to earth fault information (distance to fault).
The Swedish Neutral Earth Fault Locator utilizes fast, reliable and highly sensitive algorithms for earth fault detection. Common for the algorithms is the use of neutral voltage (UEN) and feeder summation currents as detection criteria.
The Earth Fault Locator supports all standard SCADA protocol communication.
