Induction motors are often described as “rotating transformers” due to their fundamental similarities in their operating principles and energy transfer. To understand this analogy, let’s … Read more
Open-circuit and Short-Circuit Tests of transformers are carried out to assess core losses, magnetizing current, impedance, and copper losses. These tests provide essential insights into … Read more
The k-factor of the transformer is a weighting of the harmonic load currents based on their effects on transformer heating, derived from ANSI/IEEE C57.110. Transformers … Read more
This article describes two important transformer ratios: turn ratio and voltage transformation ratio. Transformers are fundamental components in electrical engineering, playing a crucial role in … Read more
Definition: A step-up transformer transforms the low voltage on the primary side to the high voltage on its secondary side. The current on the secondary … Read more
This article describes the working and diagram of an auto transformer. The autotransformer transforms voltage and current by changing the ratio of voltage transformation. Auto … Read more
When a magnetic core reaches its limit in carrying the magnetic flux, it is called the core saturation in a transformer. This occurs when the … Read more
