Can anyone provide examples - in addition to those shown in C57.110 - of transformer derating calculations based on measured harmonic load current using the IEEE C57.110 methodology where the known data is :-
- Xfm rated sinusoidal current.
- Xfm Load Loss ( P LL ) in watts.
- d.c. resistance of primary phase winding and secondary phase winding.
- Magnitudes of individual load harmonic currents ( in amps ) through the transformer.
- Xfm rated sinusoidal current.
