IEC 62271-215:2021适用于:；相位比较器；设计为可插入电源；测试点；一个；电压检测和指示系统；（；VDIS；）根据IEC 62271-213，给出相位比较结果的指示。 主要用途是同时提供高压电网两个通电部分之间相位关系的清晰证据；标称电压；和频率，然后再进行耦合。 本第一版取消并取代1997年出版的IEC 61243-5第一版和2011年出版的IEC 62271-206第一版。本版本合并了IEC 61243-5和IEC 62271-206的内容。 本版本包括与IEC 61243先前版本相关的以下重大技术变更- 5和IEC 62271-206:；该文件不包括具体的内容；相位比较器；（SPCs）如IEC 61243-5中所定义，专门针对制造商，并收回通用相位比较器（UPC）的技术原理；VDIS；所有制造商；为了便于大型中压配电盘的相位比较操作，引入了用于顺序连接操作的相位比较器。

IEC 62271-215:2021 is applicable to;phase comparators;designed to be plugged into the;testing points;of a;voltage detecting and indicating system;(;VDIS;) according to IEC 62271-213, to give an indication of the result of a phase comparison. The main usage is to provide a clear evidence of the phase relationship between two energized parts of a high-voltage network, at the same;nominal voltage;and frequency before coupling them. This first edition cancels and replaces the first edition of IEC 61243-5 published in 1997 and the first edition of IEC 62271-206 published in 2011. This edition constitutes a merging of the content of IEC 61243-5 and IEC 62271-206. This edition includes the following significant technical changes with respect to the previous editions of IEC 61243-5 and IEC 62271-206:;the document does not include the specific;phase comparators;(SPCs) as defined in IEC 61243-5, which was specific to manufacturers, and takes back the technical principles of the universal phase comparator (UPC) for;VDIS;of all manufacturers;the phase comparator for sequential connected operation is introduced to facilitate the operation of phase comparation of large MV panels.
