What is Controlled Switching Reduces Transformer Inrush about?

This document summarizes tests performed on controlling the energization of a 100MVA, 230/138kV power transformer to reduce transformer inrush currents. The tests used a circuit breaker controller device to carefully time the closing of each circuit breaker pole such that the magnetic flux in the transformer core matched the prospective flux, nearly eliminating inrush currents. Measurements of voltages and currents during energization confirmed that inrush currents were almost completely eliminated using th
