Fungsi protèktif
U>ANSI 59
Proteksi overvoltage
Trips when the voltage rises above the setting.
I>> / I>ANSI 50/51
Proteksi arus luwih non-arah
Instantaneous (50) and IDMT time-delayed (51) tripping on overcurrent and short circuit.
IE>> / IE>ANSI 50N/51N
Proteksi grounding non-directional
Instantaneous and time-delayed protection against residual current and phase-to-earth faults.
I> →ANSI 67
Proteksi arus luwih arah
Overcurrent that checks the power direction, operating only for forward or reverse faults.
IE> →ANSI 67N
Proteksi Grounding Directional
Directional earth fault, for ring networks and parallel feeders.
I2>ANSI 46
Proteksi overcurrent komponen negatif
Detects unbalance, broken conductors and single phasing from the negative-sequence current.
θ>ANSI 49
Proteksi kakehan
A thermal model of the plant that trips before a cable, transformer or motor overheats.
CBFANSI 50BF
Proteksi kegagalan kunci
Trips the upstream breakers when a breaker fails to open after a trip command.
I> ↑CLP
fungsi deteksi beban dingin (CLP)
Raises the settings for a while after a long-dead feeder is re-energised, avoiding nuisance trips.
I2f / I1fInrush
Inrush fungsi deteksi saiki
Recognises transformer inrush from the second harmonic and blocks false trips.
Id>ANSI 87
Proteksi diferensial
Compares the currents into and out of the plant and clears faults inside the zone fast.
