Sumpner Test of Transformer: While OC and SC tests on a transformer yield its equivalent circuit parameters, these cannot be used for the 'heat run' test wherein the purpose is…
Transformer Testing Methods: Two chief difficulties which do not warrant the Transformer Testing Methods by direct load test are: Large amount of energy has to be wasted in such a…
Different types of losses in transformer: The transformer has no moving parts so that its efficiency is much higher than that of rotating machines. Different types of losses in transformer…
Approximate Equivalent Circuit of Transformer: Approximate Equivalent Circuit of Transformer - In constant frequency (50 Hz) power transformers, approximate forms of the exact T-circuit equivalent of the transformer are commonly…
Real Transformer On Load Condition | Equivalent Circuit: Figure 3.11 shows a Real Transformer On Load Condition. Both the primary and secondary have finite resistances R1 and R2 which are…
Ideal Transformer on Load: In order to visualize the effect of flow of secondary current in a transformer, certain idealizing assumptions will be made which are close approximations for a…
Phasor Diagram of Transformer on No Load: Figure 3.5 shows the schematic diagram of a Phasor Diagram of Transformer on No Load with Two Winding, i.e. the secondary terminals are…
Forced Cooling in Transformer: Forced Cooling in Transformer - For transformer sizes beyond 5 MVA additional cooling would be needed which is achieved by supplementing the tank surface by a…
