why for transformer protection we protect tranformer from 3rd hormonics and 5th hormonics and what is the reason of generating these horminics in electrical system?
2 95861.Can we create a cube in a Transformer from multiple IQD's ?if so, how? 2.Also , explain some of the best practises used ,while creating a cube in powerplay transformer.
2 10397Do I need a special Transformer to put 240 VAC 3 phase into it and and get 480 VAC 3 phase out of it to run a machine? Or, do I just use an ordinary step down transformer and step up the voltage? Thanks
