Effects of harmonics - Overloads on equipment Generators Generators supplying non-linear loads must be derated due to the additional losses caused  by harmonic currents. The level of derating is approximately 10% for a generator where the overa ll load is made up of 30% of non-linear loads. t is therefore necessary to oversi!e the gen erator. Uninterruptible power systems (UPS) The current drawn by computer systems has a very high crest factor. " #$ si!ed ta&ing into account exclusively the '( current may not be capable of supplying the necessary  pea& current and may be overloaded. ransformers • The curve presented below )see !i"# $%) shows the typical derating re*uired for a transformer supplying electronic loads Fig. M9: Derating requir ed for a transformer supplying electr onic loads
