Minimizing the Impact of Secondary Surges on Distribution Transformers

Develop Analytic Models to investigate lightning-induced surges on distribution secondaries. Determine which system parameters have the greatest effect on the first layer voltage in distribution transformers. Develop a spreadsheet which calculates the overvoltage performance of 10 and 25 kVA transformers for rural and residential circuits over a range of pole ground resistances.
