What is the Transformer of Efficiency?
Transformer Efficiency Definition
Transformer efficiency is the ratio of its output power to input power, usually between 95% and 99%.
Factors Affecting Efficiency
Efficiency depends on copper losses, iron losses, dielectric losses, and stray load losses.
Efficiency Calculation
Efficiency is calculated using OC and SC tests, which measure core and winding losses.
Maximum Efficiency Conditions
Maximum efficiency is achieved when copper losses equal core losses, typically at full load.
All-Day Efficiency
This is specific to distribution transformers and is calculated over a 24-hour period, focusing on minimizing core losses.

Rectifier vs Power Transformer: Key Differences
Differences Between Rectifier Transformers and Power TransformersRectifier transformers and power transformers both belong to the transformer family, but they differ fundamentally in application and functional characteristics. The transformers commonly seen on utility poles are typically power transformers, while those supplying electrolytic cells or electroplating equipment in factories are usually rectifier transformers. Understanding their differences requires examining three aspects: working
