介绍了曾被国家科委、国家技术监督局等主管部门评为１９９５年度“国家级新产品”并被批准为《国家级科技成果重点推广计划》项目的“相控无功自动补偿装置”，在提高各相功率因数后，降低了配电线路和变压器绕组损耗；减少了变压器电流，挖掘容量潜力；免交“功率因数调节电费”等功能之计算方法和经济效益分析。
Introduced the “phase controlled reactive power automatic compensation device” which was awarded “1995 New State Product” by the State Science and Technology Commission, the State Bureau of Technical Supervision and other competent departments and was approved as the “National Key Scientific and Technological Outreach Project” After the power factor of each phase is increased, the loss of the distribution lines and the transformer windings is reduced; the transformer current is reduced and the potential of the capacity is tapped; and the calculation method and economic benefit analysis of functions such as “adjustment of the power factor by the power factor” are exempted.
