5.6 Selecting the Calculation Method
118
A function to change the calculation methods of apparent power and reactive power when the wiring is
3P3W3M (refer to "Wiring Mode 7. 3-phase, 3-wire (3P3W3M) + single-phase, 2-wire (1P2W)" (p. 37).
When measuring the PWM waveform using the setting for rectification method "MEAN", it can improve
the mutual compatibility with measurement values of other wattmeter.
There are two types of settings, TYPE1 and TYPE2, and both are only valid during 3P3W3M wiring.
5.6 Selecting the Calculation Method
TYPE 1 The standard 3P3W3M calculation method.
TYPE 2 Calculation method to improve the mutual compatibility with 3V3A wiring of other
power meter.
Under sine wave input, there is no difference from the calculation results of TYPE1,
but when the PWM waveform is measured using the setting for rectification method
"MEAN", the values of S123, Q123,
123, and 123 is closer to the power meter for
3V3A wiring than TYPE1.
Setting Procedure
• Use TYPE1 for general use. Use TYPE2 when mutual compatibility is necessary, such as
when changing from the device currently in use.
• All measurement values are not affected except for values of S123, Q123,
123, and
123.
• When the
-Y transform function is ON, there is no difference between the calculation
results of TYPE1 and TYPE2 even with PWM waveform.
