Tool: Probabilistic Loss Evaluation Method for Transformers Serving Large Wind PlantsTool

Wind Transformer Loss Evaluation

A probabilistic, life-cycle loss-evaluation method for the Total Ownership Cost of power transformers serving large wind plants. It integrates the financial and technical characteristics together with the uncertainties of wind energy generation.

Developed by PSM Lab — supported by the Electricity Authority of Cyprus.
