摘要
对低压电器的短路试验中功率因数的测量方法进行了介绍,对目前常用的测量方法 -直流分量法、冲击系数法、相角差法、测量全阻抗法-即低电压推测法、直读法进行分析总结。并结合本试验站的实际情况,对适合的测量方法进行了探讨。
The paper presents the measuring method of the power factor for short circuit test of low voltage electricol apparatus. It has carried out analysis and summary for present common measuring method, that is DC component method, impact coefficient method, phase angle difference method and measuring absolute impidance method low voltage guess method and direct reading method. Combining with the test station conditions, we discuss right methods.
