Specifications
Four Protection Zones: Offers four zones of phase and ground distance protection, including mho and quadrilateral characteristics.
Comprehensive Tripping Schemes: Supports major pilot schemes such as POTT, DCUB, DCB, PUTT, and DTT, and is applicable for both single- and three-pole tripping.
Supplemental Elements: Includes phase, negative-sequence, and residual overcurrent protection, plus power-swing blocking and load-encroachment logic.
Adaptive Directional Elements: Features unique logic that chooses between negative- and zero-sequence quantities for reliable directional decisions.
System Monitoring: Built-in high-accuracy fault locator (reduces patrol time) and event reporting with oscillography.
I/O Flexibility: Scalable hardware with up to 16 contact inputs and 32 contact outputs.
Communication & Logic: Equipped with three serial ports (two rear, one front) and SELOGIC control equations for custom logic programming.
Versatile Mounting: Available in horizontal or vertical rack- or panel-mount configurations.
