Test code for liquid - immersed distribution , power and regulating transformers and guide for short - circuit testing of distribution and power transformers 油浸式配电电力和调压变压器的试验规程及电力和配电变压器短路试验指南
This paper particularly studied the variance analysis and the distance classification , and compared their effects in the application of circuit testing 本文详细研究了方差特征分析法和距离分类算法,并对这两种方法应用于电路测试的情况进行了比较。
The power system short circuit test bench is the important part of the dynamic simulation lab which is one of the " 211 " project items of our university 另外电力系统短路实验台是我校“ 211 ”工程建设项目? ?电力系统动态模拟实验室的重要组成部分。
Because most of the faults found at board test are manufacturing defects , fault coverage for mda tests is nearly as good as fault coverage for in - circuit tests 因为在板级测试中发现的大部分故障都是生产缺陷,生产缺陷分析测试到的故障几乎都可以覆盖在线测试所发现的问题。
The short circuit test method in this paper applies to balanced transformers , such as y / v impedance - matching balanced transformer and yna impedance - unmatching balanced transformers 利用推导的短路试验方法对一台sf2 ? qy ? 25000 ? 110 27 . 5gy型阻抗匹配平衡牵引变压器进行短路试验,解决了工程实际问题。
