The Dynamic Response of Low Voltage, High Current, Disk type Transformer Windings to through Fault Loads

In 1973, Louisiana Power & Light Company and New Orleans Public Service Inc. joined to sponsor research aimed at improving the core-form, power transformer design methods published in the literature. The specific improvement sought was in the mechanical design of continuous low voltage secondary windings of stepdown transformers to withstand the high, transitory currents caused by secondary short circuits.
