The relay type NG10 provides sensitive, high operating speed and selective differential protection against phase-to-phase and phase-to-ground short circuits of motors/generators or short lines.
STANDARD PROTECTIVE & CONTROL ELEMENTS
• Phase overcurrent side H and side L
• Maximum Residual Overcurrent
• Low impedance restricted earth fault
• Double slope biased differential for Generator/ Motor/Transformer
• Breaker Failure
• CT Supervision
• Trip Circuit Supervision
