Just like any other device . . . Output power/Input power
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
the efficiency is maximum in a transformer when no load loss is equal to load loss.
nope
For a single-phase transformer, maximum efficiency typically occurs at around 50-70% of the rated load. Operating the transformer at this load range minimizes losses and improves efficiency. Going below or above this range can decrease efficiency and increase losses in the transformer.
its efficiency will decresed.
The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss
The efficiency of a transformer is calculated by dividing the output power by the input power, then multiplying by 100 to get a percentage. In this case, the efficiency would be: (580 VA / 600 VA) * 100 = 96.67%. This means the transformer is operating at around 96.67% efficiency.
It is better to determine the efficiency of a transformer indirectly through measurements and calculations because direct loading can cause overheating and damage to the transformer. Indirect methods are safer, more accurate, and do not risk the operational integrity of the transformer.
Ambient temperature affects transformer efficiency by influencing the cooling of the transformer. Higher ambient temperatures can reduce the transformer's ability to dissipate heat, leading to decreased efficiency. It is important to consider ambient temperature when designing and operating transformers to ensure optimal performance.

A: Must understand this A transformer transfer power minus efficiency to another level that all it does.
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
