Phase-to-phase short-circuit protection, based on phase by phase comparison of the
currents on motor and generator windings.
Characteristics
*sensor saturation or disconnection
*transformer energizing (harmonic 2 restraint)
currents on motor and generator windings.
Characteristics
- instantaneous tripping
- fixed high set point for fast tripping for violent faults, with no restraint
- percentage-based characteristic with fixed slope and adjustable low set point
- tripping restraint according to percentage characteristic activated by detection of:
*sensor saturation or disconnection
*transformer energizing (harmonic 2 restraint)
