All-day efficiency means the power consumed by the transformer throughout the day. It is defined as the ratio of output power to the input power in kWh or wh of the transformer over 24 hours. Mathematically, it is represented as:
\(η={o/p\over o/p+losses}\)
Calculation:
Given, O/p = 120 kWh
Losses = 5kWh
\(η={120\over 120+5}=0.96\)
η = 96%
