29. Harmonic power measurement specications Pharm
Measurement method Indicates harmonic power for each channel and the sum for multiple channels
(For details, see Calculation Formula.)
Analysis window width 10 cycles/12 cycles
Window point count Rectangular 2,048 points
Displayed items From 0th to 50th order
Options for RMS and content percentage
For content percentage, when the RMS is 0, all orders should be set to 0%.
Measurement range Depends on the voltage × current range combination (see Power range conguration
table)
Measurement accuracy 0th order : ±0.5% rdg. ±0.5% f.s. + (current sensor accuracy)
1st to 20th order: ±0.5% rdg.±0.2% f.s. + (current sensor accuracy)
21st to 30th order: ±1.0% rdg.±0.3% f.s. + (current sensor accuracy)
31st to 40th order: ±2.0% rdg.±0.3% f.s. + (current sensor accuracy)
41st to 50th order: ±3.0% rdg.±0.3% f.s. + (current sensor accuracy)
(Note: While using 2000 A range of Model CT7742, f.s. tolerance should be 2.5 times
the value)
