功率因素和供电效率的关系

摘要

Druing the process of power supply, power factors are related to the power loss and electric energy loss from the power network, related to loss of voltage and voltage pulsation of charging line and related to the quality of power. This passage tells us the main,factors and several practical methods of low tension .%在供电过程中，用户功率因数的高低，直接关系到电力网中的功率损耗和电能损耗，关系到供电线路的电压损失和电压波动，而且关系到节约电能和整个供电区域的供电质量。文章介绍影响电网功率因数的主要因素以及低压无功补偿的几种实用方法。
