Input Specications/Output Specications/Measurement Specications
21. Current CF value measurement specications Icf
Measurement method Calculated from the RMS current and the peak value of the current waveform.
Displayed items Current CF Value
Measurement range 408.00
Measurement accuracy Accuracy not dened
22. Active power measurement specications P
Measurement method Measured every 200 ms.
Displayed items Active power on each channel
Sum of values on multiple channels (For details, see Calculation Formula.)
Inow (consumption): Unsigned
Outow (regeneration): Negative
Measurement range Depends on the combination of voltage and current ranges (see Power range
conguration table)
Measurement accuracy DC: ±0.5% rdg.±0.5% f.s. + (current sensor accuracy)
AC: ±0.2% rdg.±0.1% f.s. + (current sensor accuracy)
(Note: While using 2000 A range of Model CT7742, f.s. tolerance should be 2.5 times
the value)
Power Factor Inuence 1.0% rdg. or less (40 Hz to 70 Hz at power factor = 0.5)
Phase difference between voltage and current of the internal circuit: ± 0.2865°
23. Apparent power measurement specications S
Measurement method RMS value calculation: Calculated from RMS voltage value, Urms and RMS current,
Irms.
Fundamental wave calculation: Calculated from fundamental wave active power and
reactive power
Displayed items Apparent power on each channel
Sum of values on multiple channels
(For details, see Calculation Formula.)
Display selection RMS calculation / fundamental wave calculation (Both of them are stored.)
Measurement range Depends on the voltage × current range combination (see Power range conguration
table)
Measurement accuracy ±1 dgt. for calculations derived from the various measured values. (sum is ±3 dgt.)
