Transformer Inrush Current: Calculation & Theory ...· When a transformer is switched on from the primary side while keeping its secondary circuit open, it acts as a simple inductance. When the electrical power transformer runs normally, the flux produced in the core is in quadrature with applied voltage as shown in the figure below.. The flux wave will reach its maximum value, 1/4 cycle or π/2 angle later, reaching the maximum value of the ...
