The problems caused by transformer inrush current phenomena lead to voltage drops and current imbalances in the power system, affecting not only the specific power consumers but also surrounding businesses, public facilities, and general households. Traditional measures to address this issue require large equipment such as high-current resistors and excitation generators, and the excitation operations rely on manual processes that require experience, making it a challenging problem for those managing power facilities. Our transformer inrush current suppression device, Inrush-limiter T1, automatically controls the phase angle of the transformer circuit breaker to minimize transformer inrush current, fundamentally solving the problems caused by inrush current phenomena.
