Technical Specifications
Supply Harmonic Analysis (Frame C Normal Duty)
Assumptions: 10000A short circuit supply capability
to 73H supply impedance at 400V
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.
