摘    要:提出通过直接测量特定电压曲线的瞬时值而得到电网功因数的方法.经研究得知,电网的功率因数曲线恰好与改变了零时刻的电压曲线重合.因而只需测量改变了零时刻的特定电压曲线上对应电流峰值时刻的电压瞬时值,即测得了电网的功率因数.

关 键 词:功率因数,峰值,测量,特定曲线

Abstract:new method for measuring power factor in electrified wire netting is put forward in this paper. It's discovered that the power factor curve just coincides with the changed zero-point voltage curve. Therefore, only measuring the voltage value corresponding with the max electric current in the changed zero-point voltage curve, could the power factor of electrified wire netting be measured.
Keywords:power factor   giving curve   measuring
