CAPITALIZATION COST OF THE TRANSFORMER

Formulae for capitalization factor: = 8760 x EC x [(1+r) to the power of n – 1]

-------------------------------------

[r(1+r) to the power of n]

Where r = rate of interest

= 12% per annum (taken as a prevailing rate of Nationalized Bank)

EC = Rate of Electrical Energy

= Rs.0.76 per Kwh (As per the cost data of APGENCO for Machkund of May 2016)

N = Life of the Transformer = 35years

Capitalized cost of No load Losses

= 8760 x 0.76 x[ {(1+0.12)35 -1 } / {0.12 x (1+0.12)35]

=Rs.53,466/- per KW

Taking a Load factor of 90%, Capitalized cost of (Load loss + cooler loss)

= 0.90 x 53,466/-

= Rs.48,120/- per KW

The Capitalized cost of the transformer

= Initial cost + 53,466 x Wi (in KW) + 48,120 x Wc (in KW)

Where Wi = Difference in Iron Losses in KW from the guaranteed values

Wc = Difference in Copper Lossescum cooler loss

in KW from the guaranteed values
