摘要
Abstract
Secondary equipment debugging is a very important link in electric commissioning of power plant. But still there are defects needs to be optimized in the current debugging method, which affects the validity and correctness of the test results. In this paper, problems such as non⁃standard debugging method, unable to determine protection polarity under small current condition and unreasonable design in current transformer type selection are analyzed, therefore standardiza⁃tion debugging measures, measuring small current with multi winding line method ,the principles in selection of TA ratio and capacity are presented. These measures have been applied in power plant construction, which have achieved good results.关键词
