The power cut-off is therefore:
power cut-off= (
= ( × 0.02 pu × 1.0 V × 100 A × 13811.2 V) / 66.4 V
= 720.5 watts
Any calculated power value below this cut-off does not display. As well, the three-phase energy data do not accumulate if
the total power from all three phases does not exceed the power cut-off.
