Mešomo ya tšhireletšo
U>ANSI 59
Tšhireletšo ya gagamalo e feteletšego (ANSI 59) .
Trips when the voltage rises above the setting.
I>> / I>ANSI 50/51
Tšhireletšo ya overcurrent yeo e sego ya tlhahlo (ANSI 50-51) .
Instantaneous (50) and IDMT time-delayed (51) tripping on overcurrent and short circuit.
IE>> / IE>ANSI 50N/51N
Tšhireletšo ya fase yeo e sego ya tlhahlo (ANSI 50N-51N) .
Instantaneous and time-delayed protection against residual current and phase-to-earth faults.
I> →ANSI 67
Directional overcurrent tšireletso (ANSI 67-67 TOC) .
Overcurrent that checks the power direction, operating only for forward or reverse faults.
IE> →ANSI 67N
Tšhireletšo ya Fase ya Tlhahlo (ANSI 67N-67N TOC) .
Directional earth fault, for ring networks and parallel feeders.
I2>ANSI 46
Negative karolo overcurrent tšireletso
Detects unbalance, broken conductors and single phasing from the negative-sequence current.
θ>ANSI 49
Tšhireletšo ya go imelwa kudu (ANSI 49) .
A thermal model of the plant that trips before a cable, transformer or motor overheats.
CBFANSI 50BF
Tšhireletšo ya go palelwa ga senotlelo (ANSI 50BF) .
Trips the upstream breakers when a breaker fails to open after a trip command.
I> ↑CLP
mošomo wa go utolla mošomo wa go tonya (CLP) .
Raises the settings for a while after a long-dead feeder is re-energised, avoiding nuisance trips.
I2f / I1fInrush
Inrush jwale phumano mosebetsi
Recognises transformer inrush from the second harmonic and blocks false trips.
Id>ANSI 87
Tšhireletšo ya phapano (ANSI 87) .
Compares the currents into and out of the plant and clears faults inside the zone fast.
