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

Technical Specifications 9-19
650V AC Drive
Supply Harmonic Analysis (Frame E 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.
