Setting Test Conditions (61000-3-12)
8
Check that the phase angle of the fifth harmonic current is 90 to 150°
against the phase angle of the fundamental voltage.
Check for each phase.
9
Check that the fifth and seventh harmonic current values are less than
5% of the reference current value/reference fundamental current value.
Check for each phase.
10
Press the F6 key to return.
Determining the Limit Value
11
Determine the limit value according to the limit value standard.
Regarding the condition “The phase angle of the fifth harmonic current of the EUT against the
fundamental voltage is designed to change with time to take all values from 0° to 360°,” under
which the limit value table (Standard Table 4) of the balanced three-phase equipment with
specified conditions can be used, customers are asked to investigate the details themselves.
