TYPE EKL
The earth-fault and short-circuit indicator type EKL can be used in radial networks with one input and open-ring networks which are solidly earthed or low resistance earthed.The indication of short-circuits is done by one or three LEDs. Earth-faults are indicated by one LED. The potential-free connection between the short-circuit sensors and the display unit is done by fiber optic cables. The short-circuit sensors can be mounted on screened and unscreened cables. The connection between the earth-fault sensor and the display unit is done by cable. The 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.
The earth-fault and short-circuit indicator type EKL can be equipped with a second relay for a separate remote indication of earth-faults and short-circuits.
