Transformer Losses ~ Payback Calculation
This spreadsheet compares the losses and costs of two 1250 KVA transformers over a 15 year period. Transformer-2 has lower no-load and full-load losses, resulting in lower total annual losses of 16,726 KWh and a lower total ownership cost of Rs. 3,36,321. The simple payback period for the more efficient Transformer-2 is calculated to be 1.40 years, with an annual rate of return of 71%.

FAQs:
How do you calculate transformer loss?
Copper loss is generally 0.5%. Iron loss is generally 5~7%. Transformation loss of dry-type transformer is smaller than oil-immersed one. Total transformation loss: 0.5+6=6.5 Calculation method: 1000KVA×6.5% = 65KVA 65KVA×24 hours×365 days = 569,400KWT The labels on the transformers usually contain specific data.
What are the 5 losses of transformers?
Transformers experience various types of losses, including iron loss, copper loss, hysteresis loss, eddy current loss, stray loss, and dielectric loss.S
How do you measure transformer loss?
Measurement of transformer loss
As when measuring overall loss in a circuit, transformer loss can be measured by measuring the input and output power for the transformer being measured and then calculating the difference.
What is the loss of a 500 kVA transformer?
Transformer kVA rating = 500 kVA. No-load loss = 900 watts (assumed to be constant) Copper loss at full load = 6400 watts.
