Equivalent circuit of transformer
The equivalent circuit of transformer is a circuit representation of equations that describes the performance of the device. The equivalent circuit of transformer is used to predetermine the behavior of…
Equivalent resistance and reactance of transformer
The transformer has two independent circuits primary and secondary winding. The two circuits can be resolved into an equivalent circuit to make the calculations simple. Consider a practical transformer as…
Phasor diagram of practical transformer on Load
A practical or actual transformer will have winding resistance and leakage reactances both on the primary and secondary sides. When the secondary of the transformer is connected to the load…
Energy Efficiency – Importance and benefits
Energy efficiency is an effective way of using less energy to perform the same task. It refers to the extent to which a device, building, or system uses energy effectively….
Transformer with winding resistance and leakage reactance
Resistance of transformer An ideal transformer has no losses because it possesses no resistance. It is not possible to build an ideal transformer. But an actual transformer always has some…
Transformer on load condition
A transformer is said to be on load when the primary is connected to the alternating voltage source and its secondary is connected to the load. When a transformer is…
Operation of Transformer on No load condition
A transformer is said to be at no load when the primary of a transformer is connected to the source of ac supply and the secondary is kept open. Similarly,…
What is an Ideal Transformer? Properties, Working, and Phasor diagram
An ideal transformer is a transformer that has no winding resistance(no copper loss), no core loss, no magnetic leakage, and zero magnetizing currents. But in existence, there is no such…
