Study on Inherent Delay Test of Electronic Transformers Sampling System

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.
