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…
Phasor Diagram of Transformer: For the approximate equivalent circuit of Phasor Diagram of Transformer is shown in Fig. 3.16(b) The phasor diagram corresponding to this equation is drawn in Fig.…
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…
Transformer Cooling System: Transformer Cooling System (Large Units) - Basically, there are two seats of losses in a transformer namely: Core, where eddy current and hysteresis losses occur (caused by…
Construction of Transformer and types of transformer: Construction of Transformer is intimately related to the purpose for which these are to be used; winding voltage, current rating and operating frequencies.…
