Define transformer efficiency and its formula.
1 Answer
Transformer efficiency refers to the ratio of output power to input power in a transformer. In an ideal transformer, all the energy from the primary (input) side should be transferred to the secondary (output) side without any losses. However, due to various factors such as resistive losses, core losses, and other inefficiencies, some of the input power gets dissipated as heat, leading to a reduction in the actual output power compared to the theoretical ideal.
The formula for transformer efficiency (Ī·) is given by:
Ī· = (Output Power / Input Power) Ć 100%
Where:
Ī·: Efficiency (expressed as a percentage)
Output Power: Power delivered to the load on the secondary side of the transformer
Input Power: Power supplied to the primary side of the transformer
Efficiency is an important consideration in the design and operation of transformers, especially in applications where energy conservation and minimizing losses are critical. Higher efficiency transformers are preferred as they waste less energy and generate less heat, leading to better performance and reduced operating costs.
