line vltage of three phase distribution transformer is 433v and phase voltage is 250v,but we required 230v for domestic distribution,then how we reduce phase voltage of transformer
5 60261. What are the tests to be carried out for CBCT? 2. can measure the secondary resistances? 3. with respect to secondary maximum how much voltage can be applied for IR test.
1412if harmonics is generates on the secondary side of transformer then why we put LC ckt on prim side?(i m talking abt rectiformer transformer)
