If you are involved in transformer (oil immersed) maintenance in your company, here is a list of common tests required to be done on oil immersed transformers according to IEC 60076-1 : …

Transformers are usually provided with a rating plate of weatherproof material situated in a visible position. All entries on the plate are usually indelibly marked. According to the IEC 60076-1 s…

Increasing the cooling rate of a transformer increases its capacity to handle more power requirements. Various methods exist for cooling oil immersed industrial transformers to guarantee efficient …

Transformers are rated using several methods. Two common ratings of transformers include the: (a) KVA rating (b) Impedance rating KVA Rating KVA ratings of transformers are obtained by si…

Transformers having only one winding are called autotransformers. This is the most efficient type of transformer since a portion of the one winding carries the difference between the primary and …

Instrument transformers are used for measuring and control purposes. They provide currents and voltages proportional to the primary, but there is less danger to instruments and personnel. There…

The capacity or rating of a transformer is limited by the temperature that the insulation can tolerate.  The life of a transformer can be extended by making sure it is not operated over and above t…

Transformer function is based on the principle that electrical energy is transferred efficiently by magnetic induction from one circuit to another. Basically, a transformer consists of two or more …
