What is Transformer Inrush Current Analysis about?
1) Random energization of power transformers can lead to core saturation and high inrush currents that can damage equipment. 2) Controlled switching aims to reduce inrush currents by calculating the optimal timing to close the circuit breaker based on residual flux and applied voltage sinusoidal flux. 3) Case A ignores residual flux and closes at the voltage peak to minimize flux. Case B accounts for residual flux by measuring it and closing with total flux equal to zero.
