Application
The relay provides time graded directional phase
and earth fault protection of generators,
trasformers, capacitors, etc.
Principal of Operation
JNP 096/096P provides directional over current protection for power systems. The Relay operating time is determined by selectting definite time characteristics or one of the four inverse time
characteristics i.e. (3s normal inverse, 1.3s normal inverse, very inverse and extremely inverse).
The operating region is defined by the characteristic angle selected. The relay measures the
current and voltage from each of the phases and if the phase angle in the operating zone of the
relay, then the relay extends trip signal.
