Description
The ENLZ devices are designed for short-circuit fault detection by means of single-phase short-circuit current sensors with optical output, as well as detection of single-phase earth faults by means of measuring synchronised vectors of currents and/or voltages of short-circuit faults. One ENLZ device can monitor up to two feeders. In combination with ENKM-3 data acquisition devices and WEB-OIC software complex, ENLZ allows to determine the type and area of failure in 6/10 kV distribution networks.
