Mintirho yo sirhelela
U>ANSI 59
Nsirhelelo wa voltage yo tlula mpimo (ANSI 59) .
Trips when the voltage rises above the setting.
I>> / I>ANSI 50/51
Nsirhelelo wa ku tlula mpimo lowu nga kongomisiwangiki (ANSI 50-51) .
Instantaneous (50) and IDMT time-delayed (51) tripping on overcurrent and short circuit.
IE>> / IE>ANSI 50N/51N
Nsirhelelo wa misava lowu nga kongomangiki (ANSI 50N-51N) .
Instantaneous and time-delayed protection against residual current and phase-to-earth faults.
I> →ANSI 67
Nsirhelelo wa gezi ro tlula mpimo leri kongomisiweke (ANSI 67-67 TOC) .
Overcurrent that checks the power direction, operating only for forward or reverse faults.
IE> →ANSI 67N
Nsirhelelo wa Misava wa Nkongomiso (ANSI 67N-67N TOC) .
Directional earth fault, for ring networks and parallel feeders.
I2>ANSI 46
Nsirhelelo wa xiphemu xo biha xa overcurrent
Detects unbalance, broken conductors and single phasing from the negative-sequence current.
θ>ANSI 49
Nsirhelelo wa ndzhwalo wo tlula mpimo (ANSI 49) .
A thermal model of the plant that trips before a cable, transformer or motor overheats.
CBFANSI 50BF
Nsirhelelo wa ku tsandzeka ka xilotlelo (ANSI 50BF) .
Trips the upstream breakers when a breaker fails to open after a trip command.
I> ↑CLP
ntirho wo kuma ndzhwalo wo titimela (CLP) .
Raises the settings for a while after a long-dead feeder is re-energised, avoiding nuisance trips.
I2f / I1fInrush
Ntirho wo kuma sweswi wa Inrush
Recognises transformer inrush from the second harmonic and blocks false trips.
Id>ANSI 87
Nsirhelelo wa ku hambana (ANSI 87) .
Compares the currents into and out of the plant and clears faults inside the zone fast.
