The L90 provides a differential current protection suitable for high-speed transmission lines and cables of different voltage levels, while support full distance protection applications and double switch suitable for single and three-pole tripping applications.


The L60 provides subcycle comparison protection quickly and safely phase for both lines two terminals and three terminals, series compensation lines, and one shot applications pole and three poles.


The L30 is a current relay profitable line differential protection intended for sub-transmission lines and medium voltage cables that provide reliable and safe operation even in the worst conditions of the power system case. The L30 provides fault detection and high-speed secure adequate space for applications three-pole tripping. The L30 supports communications between relays directly via fiber and RS422 standard G.703, C37.94 and telecommunication interfaces. The L30 also provides Synchrophasor measurements over Ethernet according to IEEE C37.118.
