Waveshape sampling
8000 V pk
200 nS
± 5 % reading ± 20 V (test parameters: 1000 V dc, 1000 V rms, 100 kHz)
True rms (one cycle calculation by overlapping each half cycle - voltage between lines is measured
for 3P3W lines and phase voltage is measured for 3P4W lines)
Amplitude and duration of swell
Same as rms voltage
True rms (one cycle calculation by overlapping each half cycle - voltage between lines is measured
for 3P3W lines and phase voltage is measured for 3P4W lines)
Amplitude and duration of dip or interruption
Same as rms voltage
Same as voltage dip
True rms calculated continuously: every cycle, and every 10 or 12 cycles at 50 or 60 Hz respec-
tively, as required by standards
+/- (voltage uncertainty + current uncertainty + current probe uncertainty)
