transformer
Efficiency of Transformer: Formula, Calculation & Maximum Efficiency Explained
The transformer is a vital link between the load and the supply. The efficiency of the transformer is very important in view of energy saving.
Derive EMF Equation of Transformer with Diagram and Examples
Understanding the EMF equation of transformer is essential to grasp how transformers work. When a sinusoidal AC voltage is applied to the primary coil, it
Transformer Over Fluxing Protection
Transformer Over Fluxing Protection protects the core from overheating caused by over-fluxing. The voltage and frequency ratio (V/f) is responsible for over-fluxing in the transformer.
Over Fluxing in Transformer: Causes, Effects, and Permissible Flux Limits
Overfluxing in transformer is a critical condition that occurs when the voltage-to-frequency ratio (V/f) exceeds its designed limit, leading to an abnormal rise in core

Transformer Magnetizing Inrush Current
When energizing a power transformer, the transformer draws a magnetizing current. The magnitude of the magnetizing current is several times higher than the rated current
Why LV Winding Is Placed Next To The Core?
In a transformer, the LV (Low Voltage) and HV (High Voltage) windings are arranged strategically for performance and safety. One common design is to place
Copper Loss in Transformer – Explanation, Formula & Reduction Methods
The copper loss in the transformer is equal to the I2R loss. The copper loss is very important for the calculation of the transformer efficiency.
No Load Losses of Transformer – Formula & Core Loss
Transformers, even when not supplying any load, consume power—this is known as no-load loss or core loss. These losses occur as soon as the transformer
