Short-circuit indicator EKL series

ground faultLEDpanel-mount

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 fibre 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. The earth-fault and short-circuit indicator type EKL consists of: – One display unit for displaying earth-faults and short-circuits – Three sensors type LK for detecting short-circuits – One sensor type SE for detecting earth-faults The earth-fault and short-circuit indicator type EKL is available in two versions: Type EKL 1.2: Short-circuit indication by one common LED for all three phases Type EKL 3.2: Short-circuit indication by one LED for each of the three phases Both versions provide an earth-fault indication with one LED.
