Transformer
(Sustainable
procurement)
ABB’s line of distribution transformers can reduce operating costs, energy
bills and overall environmental impact?
The low-loss transformers can decrease electrical losses significantly. In fact,
if all transformers were replaced by amorphous metal core transformers, the
newest technology, distribution network losses could be reduced up to 70
percent.
These energy savings would ultimately mean lower operating costs and
reduced environmental impact.
As an added performance and environmental enhancement, our low-loss
transformers can be specified with our proprietary high temperature and
biodegradable insulation fluid.
ABB transformers with BIOTEMP fluid offer the optimum combination of
performance and safety.

12. Cost benefit
analysis(Total
ownership cost)
In light of global climate concerns, many users agree that low loss
transformers should be chosen on criteria other than pure short term
profitability aspects. When purchasing transformers
ABB recommends the use of total ownership cost (TOC) which considers
the future operating costs of a unit over its lifetime, brought back into
present day cost and then added to its total purchase price.
In calculating TOC, the losses are evaluated by their financial impact,
capitalized for an expected payback period for the transformer.
Where
Ct = Transformer purchase price
A = Assessed financial value (e.g., USD/W), or capitalization factor,
for no-load loss
B = Assessed financial value (e.g., USD/W), or
capitalization factor,
for load-loss P0 = No load Loss
Pk = Load Loss
T1= c1 +(A*p0) +(B*pk)
The equation

13. Continued….
•With low loss, high efficiency transformers, the
higher material cost typically requires a higher
first cost.
• However, this will be compensated by reduced
running costs from lower losses
•Beyond a certain time, the lower losses will give
a net financial saving from reduced energy costs.
If higher loss transformers are replaced with new
low loss transformers,
•This saving becomes even greater. Furthermore,
lower losses result in cost avoidance derived
from elimination or deferral of extra generation
and transmission capacity additions.
