Contents of Automatic Setting of Events (thresholds)
Items Default setting of
ON/OFF
Only those lines used in
the set wire connection
are ON; the remainder
are OFF. CH4 is OFF
when AC is set.
Setting of levels
The current measured values shall be used as the
reference values. All hystereses should be 1% of
the levels (thresholds). The levels (thresholds)
are as specified below.
Transient overvoltage ON 150% of the reference value (RMS voltage value)
Voltage swell ON 110% of the nominal voltage value
Voltage dip ON 90% of the nominal voltage value
Interruption ON 10% of the nominal voltage value
Waveform distortion ON 5% of the range
Frequency ON ±5Hz of the reference value (frequency)
RMS voltage value ON (SENSE OFF,
SENSE width10 V)
±10% of the reference value (RMS voltage value)
Voltage waveform peak (max) ON 150% of the reference value (maximum voltage
waveform peak
value)
Voltage waveform peak (min) ON 150% of the reference value (minimum voltage
waveform peak
value)
RMS current value ON ±50% of the reference value (
RMS current value)
Current waveform peak (max) ON 200% of the reference value (maximum current
waveform peak
value)
Current waveform peak (min) ON 200% of the reference value (minimum current
waveform peak
value)
Active power
(The final ch is the SUM value.)
ON 150% of the absolute value of the reference value
(active power)
Apparent power
(The final ch is the SUM value.)
ON 150% of the absolute value of the reference value
(
apparent power)
Reactive power
(The final ch is the SUM value.)
ON 150% of the absolute value of the reference value
(
reactive power)
Power factor
(The final ch is the SUM value.)
ON If lower than 70%
K factor ON If higher than 10
Voltage unbalance factor ON If higher than 3%
Current unbalance factor ON If higher than 35%
Harmonic voltage Fundamental
wave
ON 110% of the absolute value of the reference value
(fundamental wave of the harmonic voltage)
Harmonic
wave
ON only in odd-num-
bered order up to elev-
enth order.
The remainder are OFF.

ON 150% of the absolute value of the reference value
(fundamental wave of the harmonic current)

ON only in odd-num-
bered order up to elev-

The remainder are OFF.
