Power Transformers
We manufacture power transformers as per IS 2026, IS 6600, IEC 60076 & IS 1180 standards.
Power Transformer manufacturing range: Upto 10 MVA, 33kV
Method of cooling: Oil Natural Air Natural (ONAN)
Power transformer is applicable to Station & Multi-winding to suit specific needs & L.T. Transformers for generating Stations.
A Power transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction.
A varying current in the transformer's primary winding creates a varying magnetic flux in the core and a varying magnetic field impinging on the secondary winding. This varying magnetic field at the secondary induces a varying electromotive force (EMF) or voltage in the secondary winding. Making use of Faraday's Law in conjunction with high magnetic permeability core properties, transformers can thus be designed to efficiently change AC voltages from one voltage level to another within power networks.
