Analysis of the economic benefits to new energy-saving distribution transformer

Calculating the power loss of amorphous core transformer (AMT), S11 and S7 type distribution transformers in the same capability, and comparative analysis the economic benefits between AMT and S11 type transformer. It can be concluded that the effect of energy-saving of AMT is superior to the energy-saving effect of S11 type distribution transformers, and if replace the S7 type transformer by AMT in the existing circumstances, the higher investment of the AMT than S11 type transformer can be recovered by the power-saving benefits in a relatively short period of time.
