Parker 650V series - Supply Harmonic Analysis (Frame E Heavy Duty)

9-22 Technical Specifications
650V AC Drive
Supply Harmonic Analysis (Frame F Heavy 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.
