How to step up ac voltage

WebMar 21, 2024 · A step-up transformer is used to increase the transmission voltage to reduce line losses. By increasing voltage, line current proportionally decreases, and power loss … WebAlthough the transformer can step-up (or step-down) voltage, it cannot step-up power. Thus, when a transformer steps-up a voltage, it steps-down the current and vice-versa, so that the output power is always at the same value as the input power. Then we can say that primary power equals secondary power, ( P P = P S ). Power in a Transformer
