摘要
传统的测量变压器绕组直流电阻的方法常常带来人为的误差,提出了一种基于虚拟仪器的变压器直流电阻八线制测量的方法,在每相测量前引入了有效的接地,对于YN接法的绕组实现了三相同时测量,该方法测量精度高,速度快,测量范围宽,能自动操作。
In view of the traditional measuring method for DC resistance of transformer windings often brought about personal errors,a 8-wire measuring system based on virtual instrument is studied.Each phase winding is grounded before measuring,so each phase DC resistance of the YN connected windings could be measured at the same time.This measuring method has the advantages of high precision,wide measuring range and fully automatic processing.
