What is an On-Load Tap Changing Transformer & Its Working
Webb30 jan. 2024 · A power transformer is used to convert power from one circuit to another without changing its frequency. They are usually large in size and do not have any rotating or moving parts. The transformer works on the principle of mutual induction and requires an AC supply. Power transformer ratings are as follows 400kv, 200kv, 110kv, 66kv, 33kv. WebbOLTC (on load tap changer)is a mechanism used in transformer. for changing the tapping position on primary side (HV)of. transformer.For any installation mostly in industrial areas. and rural areas the voltage on HV of the transformer will. not be 11kv (taking an example of 11kv System)and. Webb15 apr. 2024 · Out of all four transformer losses, core losses and copper losses are obtained in the transformer in more quantity. So while calculating, we can neglect stray loss and dielectric loss. The total calculation of the transformer loss is given by.
