Percentage Impedance क्या होता है ?? | What Is Percentage Impedance ? Percentage impedance, also known as impedance percentage or impedance, is a measure used in electrical engineering to represent the impedance of a transformer or other electrical equipment relative to its rated impedance. It is expressed as a percentage. For transformers, the percentage impedance is calculated as the ratio of the rated voltage to the rated current at full load, multiplied by 100. This value indicates the level of internal impedance in the transformer and affects its ability to handle short-circuit currents and voltage regulation. A higher percentage impedance implies a greater voltage drop under load conditions. In summary, percentage impedance is a crucial factor in assessing the performance and suitability of electrical equipment like transformers in power systems.
