I am currently experiencing problems with harmonics generated by a 20KVA UPS. The 11th and 13th harmonics are the problem harmonics. I will like to design and install LC harmonic filters. What are the equations for this design and are there alternate solutions to this problem.
Thanks.

Are you talking about current or voltages ?

On the input or on the output?

Three Pase or Single Phase ?
