سسیستم های سه فازه

در نیروگاه های برق یک ژنراتور الکتریکی توان مکانیکی را به یک دسته از جریان های الکتریکی متناوب تبدیل می کند که از هر کدام از سیم پیچ های الکترومغناطیسی یا سیم پیچ های ژنراتور تولید می شوند. جریان ها همگی توابعی سینوسی از زمان هستند و همگی دارای فرکانسی مشابه اما با زاویه های فاز متفاوت.

در كشورهای صنعتی، سه فاز روش عمومی انتقال توان سه فاز است. این سیستم در وقع نوعی از سیستم چند فاز است.
