PRODUCT INFORMATION

EARTH-FAULT and short-circuit indicator

TypE EKL8000

The earth-fault and short-circuit indicator can be used in radial networks with one input and open-ring networks which are solidly earthed or low resistance earthed. The indication of the short-circuit is done by one LED indicator for each phase and one LED for earth-fault indication. The potential-free connection between the short-circuit sensors and accordingly the earth-fault sensor to the display unit is done by fi bre optic cables. The short-circuit sensor can be mounted on screened and unscreened cables.

The connection between the earth-fault sensors and the display unit are done by potential-free fibre optic cables. The earth-fault sensor must be mounted on screened cables. All sensors are divisible and can be retrofitted on the cable. The display device is powered by an exchangeable lithium battery. Alternatively, the display device can be connected to an auxiliary power supply that should not fail in case of a fault.

The earth-fault and short-circuit indicator type EKL8000 consists of:

– One display unit for displaying the earth-fault and short-circuit
– Three sensors type LK (page 17) for detecting the short-circuit
– One sensor type LE (page 18) for detecting the earth-fault
