Protection of generators with earthed neutral against phase-to-earth insulation faults,
by the detection of a reduction of third harmonic residual voltage.
Protects the 10 to 20 % of the stator winding, neutral point end, not protected by the
ANSI 59N/64G1 function, neutral voltage displacement.
Characteristics
*adaptive neutral and terminal third harmonic voltage comparator set point
by the detection of a reduction of third harmonic residual voltage.
Protects the 10 to 20 % of the stator winding, neutral point end, not protected by the
ANSI 59N/64G1 function, neutral voltage displacement.
Characteristics
- choice of 2 tripping principles, according to the sensors used:
*adaptive neutral and terminal third harmonic voltage comparator set point
- time-delayed definite time (DT) tripping.
