浅谈采用就地计量方式降低PT二次压降

Brief Discussion of Adopting the Local Measurement Mode to Reduce the Secondary Voltage Step-down

电能计量装置的准确与否 ,直接关系到供用电双方的经济效益。而PT二次压降又是引起电能计量装置综合误差的直接原因之一。文章以黄化供电局对大用户计量装置改造为例 ,详细介绍了几种利用就地计量方式来降低PT二次压降的方法 ,从而减少供电部门电能计量损失。

It is Directly concerns the economic benefit of the two aspects which is power supply department and the power consumer whether the electric energy metering equipment is accuracy. PT secondary voltage step-down is one of the reason which causes the comprehensive error of the electric energy metering equipment. The paper introduces several methods to reduce the PT secondary Step-down by using the example of Huanghua power supply bureau's activity of transforming the equipment of the big power consumer, in order to reduce the electric power metering loss of the power supply department.
