摘要
电子式互感器采样系统固有延时是合并单元同步补偿的依据,采样系统的固有延时误差是电子式互感器相位误差的主要因素,采样系统的固有延时测试一直是电子式互感器的测试难点和重点。本文首先对电子式互感器采样系统固有延时的定义进行了阐述,介绍了电子式互感器采样系统固有延时测试的现状,提出一种通过三个阶段精确测量了电子式互感器采样系统固有延时的方法,并与电子式互感器校验仪通过相互印证明确了该测试方法的正确性,对于电子式互感器的开发、测试与检定具有重要意义。
Electronic transformers sampling system inherent delay is merge unit synchronous compensation basis,sampling system inherent delay error is main factor of electronic transformers phase error,sampling system inherent delay test has been electronic instrument transformers testing difficult and important.This article expounds the definition of electronic transformers sampling system inherent delay,introduces electronic transformers sampling system inherent delay test of the status quo,proposes a through three stages in electronic transformers accurate measurement method of sampling system inherent delay.And electronic transformers verification through mutual confirm clearly the test method is correct,and it has important significance for electronic instrument transformers development.testing and verification.
