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 uniformly spread throughout the winding;…
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 practical transformer. A transformer possessing…
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 open while the primary is…
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 separate radiator in which oil…
Natural Cooling System in Transformer: Natural Cooling System in Transformer - Smaller size transformers are immersed in a tank containing transformer oil. The oil surrounding the core and windings gets heated, expands and moves upwards.…
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 alternating density). Windings (primary and…
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. The construction has to ensure…
How does a Transformer Work and Purpose of Transformer: How does a Transformer Work - A Transformer Circuit is a static device comprising coils coupled through a magnetic medium connecting two ports at different voltage…
