Thermal coefficient measurements of typical distribution transformers operating under imbalance conditions [abstract only]

Transformers play a key role in power distribution networks. A reliable and endless supply of electricity is highly dependent on good operation of these elements. A huge number of customers are directly supplied via any of the transformers. Loading of transformers under imbalance conditions is an important factor that influences the life of their insulation. This paper primary refers to thermal coefficients measurement and life assessment of two typical distribution transformers with the same parameters but different operating conditions.
