UTXvL – Computers & Control

Relay UTXvL

UTXvL series 3 is designed to protect cable and overhead feeder bays, the main transformer bay, auxiliary needs, the coupling and the capacitor bank bay.
The basis for reliable operation of the protection is: precise and fast measurement of analog quantities and precise calculation of voltage, current and ground admittance vectors.
The device is standardly equipped with a package of PAX relay outputs (a package of 4 strong and fast outputs).

UTXvL protection is available in the following versions:

L/4 – version with four analog inputs (IL1, IL2, IL3, U4 (EU));
L/5 – version with five analog inputs (IL1,IL2,IL3,I4(IE/IG),U4(UE));
L/8 – version with eight analog inputs (IL1,IL2,IL3,I4(IE/IG),UL1,UL2,UL3,U4(UE/Usync)), in this version the functions of voltage stages, power and energy measurement are available e.t.c.;
L/10 – version with ten analog inputs (IL1,IL2,IL3,I4(IE),IG,UL1,UL2,UL3,U4(UE),Usync), in this version the functions of voltage stages, power and energy measurement are available e.t.c.;
