K Factor, harmonic distorsion

[Mayimbe]

me again

does anybody know something about the K factor generated by computers and air conditioning (window type)? or for desktop computers only?

any reference?

for design.

 

[mcclary's electrical]

For design purposes, A k factor of k1-k4 will normally work with most transformers,,,however, technically anthing over a 1.0 will require derating of the transformer. Harmonis of non-linear loads can be damaging to neutrals. Not too mention interference.
