All About The All Day Efficiency Electrical Transformer , Its A Useful Or Not And How To Calculate The All Day Efficiency Of Electrical Transformers!!!!

(A) ordinary or commercial efficiency

The Commercial Efficiency Of a Transformer is defined as the ratio of power output to power input in (watts or kilowatts)

Commercial efficiency =  output in watts or kW / Input in watts or kW

(b) All-day efficiency

Transformers used to stepdown the Distribution Voltage to a standard service voltage or from transmission voltage to distribution voltage are called distribution transformers.

They are connected for the whole intermittentle.

Day to the line but loaded whether they They are kept in operation all the 24 hours a day are carrying any load or not.

Thus the iron losses occur for the whole day but Copper Losses occur only when the transformer is delivering the load current.

Hence if the transformer is not used to supply the Load Current for the whole day, all day efficiency will be less than ordinary or commercial efficiency.

The All Day Efficiency is defined as the ratio of energy output in kwh to the input in kWh during the whole day.

Efficiency (all day)  = Output in kWh /Input in kWh for 24 hours

In order to determine the all-day efficiency, the load cycle (or the period for which the transformer is loaded) in 24 hours should known.
