Transformers 6 Harmonics
Transformers 6 Harmonics
(OP)
Does any one heard about using double screen in transformers, one in the primary side and one in the secondary, to avoid drive harmonics?
Thanks.
Thanks.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Discribe the problem with harmonic data, voltages and system size

I don’t think ANSI standards address shielding as a means of harmonic reduction. Ref: ANSI/IEEE C57.110-1986 Establishing Transformer Capability When Supplying Nonsinusoidal Load Currents

Transformers are distribution transformers, dry type, delta-delta, 2500KVA, 6600/440V.
It's just a requirement in an offer so there aren`t any details about the harmonics problem.
As "busbar", I think drive harmonics can not be affected by any kind of screen...
