The application is designed to calculate the cost of power and energy losses in power transformers and autotransformers. It is designed to use the data of the following types of transformers:
a two-winding transformer - voltage transformer having a secondary winding voltage;
three-winding transformers - voltage transformer having two secondary windings: primary and secondary.

Parameters for input:

n - Number of parallel transformers (u.)
Snom - Rated power transformer (kVA)
Smax - Transformer load at maximum capacity (kVA)
Shv - Estimated capacity on the side of higher voltage (HV) transformer (kVA)
Smv - Estimated capacity on the medium voltage (MV) transformer (kVA)
Slv - Estimated capacity on the side of low voltage (LV) transformer (kVA)
ΔPnl - No-load losses of the transformer (kW)
ΔPsc - Loss of the transformer short circuit (kW)
Psc(h-m) - Loss of short-circuit of the high-voltage to the mean (kW)
Psc(h-l) - Loss of short-circuit from the highest to the lowest voltage (kW)
Psc(m-l) - Loss of short-circuiting of the medium voltage to the lowest (kW)
Inl - The value of load current of the transformer (%)
Usc - Short-circuit voltage of the transformer (%)
Usc(h-m) - Short-circuit voltage from a higher voltage to the mean (%)
Usc(h-l) - Short-circuit voltage from a higher to a lower voltage (%)
Usc(m-l) - Short-circuit voltage of the medium voltage to the lowest (%)
Tmax - The time value of the maximum load of the transformer (h.)
Tmax(hv) - The time value of the maximum load on the HV side of the transformer (h.)
Tmax(mv) - The time value of the maximum load on the MV side of the transformer (h.)
Tmax(lv) - The time value of the maximum load on the LV side of the transformer (h.)
Ty - Number of hours of the transformer for the year (h.)
C¤ - The average tariff for active power (¤/kWh.)

Parameters obtained after calculations:

Kl - The load factor of the transformer (rel.u.)
ΔPt - Total losses of active power transformer (kW)
ΔQt - Total losses of reactive power transformer (kvar)
ΔSt - Full power losses in the transformer (kVA)
t - The time of maximum losses (h.)
t(hv) - The time of maximum losses on the HV side (h.)
t(mv) - The time of maximum losses on the MV side (h.)
t(lv) - The time of maximum losses on the LV side (h.)
ΔWat - Active energy losses in the transformer during the year (kWh.)
ΔWrt - Reactive power losses in the transformer for the year (kvarh.)
ΔWt - The total energy loss in the transformer (kVAh.)
C - The annual cost of energy loss (¤ per year)
