RL-Series Advanced detection /
Sectionalising features

Fault detection

Phase fault detection
Phase fault detection monitors all three phases and makes event log entries
on through-fault detection.

b Phase faults setting range: 10 - 1260 A
b Setting resolution: 1 A
b Detection time range: 0.01 - 100 s
b Time resolution: 0.01 s

Earth fault detection
Earth fault detection monitors earth faults and makes event log entries on through-
fault detection.

b Earth faults setting range: 10 - 1260 A
b Setting resolution: 1 A
b Detection time range: 0.05 - 100 s
b Time resolution: 0.01 s

Sensitive Earth Fault (SEF)
SEF causes a fault to fl ag when the earth current rises above a set level for longer
than the set time.

b SEF current range: 4 - 20 A
b SEF operating time range: 0.1 - 999 s
b SEF current setting resolution: 1 A
b SEF operating time resolution: 0.1 s

Defi nite time protection
Defi nite time works by fl agging a fault at a fi xed time after pick-up.

b Setting current range: 10 - 1260 A
b Defi nite time resolution: 0.01 s
b Defi nite time range: 0.01 - 100 s
b Setting current resolution: 1 A

Inrush restraint
Inrush restraint raises the phase and earth threshold currents for a short period of
time to allow for short duration inrush currents when closing onto a load.

b Multiplier range: 1 - 30
b Multiplier resolution: 0.1
b Time range: 0.05 - 30 s
b Time resolution: 0.05 s

Sequence components
Negative, positive and zero phase sequence currents and voltages can be
monitored and logged.
In addition, the negative phase sequence current detection can be used for detection
of low-level phase-to-phase faults in the presence of high level three-phase loads.

b Setting current range: 10 - 1260 A
