Parker 650V series - Supply Harmonic Analysis (Frame C Normal Duty)

Technical Specifications 9-17
650V AC Drive
Supply Harmonic Analysis (Frame D Normal Duty)
Assumptions: 10000A short circuit supply capability, equivalent
to 73µH supply impedance at 400V where Q
1n
is the rated rms
value of the fundamental voltage of the supply transformer. The
results conform to stage 1, stage 2 and stage 3 of the
Engineering Recommendation G.5/3 September 1976,
Classification ‘C’: Limits for Harmonics in the UK Electricity
Industry.
