| Abstract: | The economic life of power transformer is determined by the year when the average annual cost is the lowest,And the average annual cost not only relates to the purchasing cost and the use-maintenance cost,also relates to the loss cause by transformer breakdown.Based on the model of economic life,the method of risk analysis has application in economic lift of power transformer,and an applied computational methods of power transformer fault risk is proposed,the maintenance costs and operation costs are analyzed,the new economic life model of power transformer is established.Combined with the maintenance data of old transformer,the forecast method of transformer economic life is verifed,Forecast results show that this method is satisfactory. |
| Keywords: | power transformer risk analysis average annual cost economic life prediction |
