基于路由采样时基同步的电子式互感器数字输出校验方法
Calibration System of Electronic Transformers with Digital Output Based on the Routed Sample Clock
摘要
Abstract
Calibration system with digital output is realized by construction of standard channel,digital processing of standard channel,receiving the digital output of MU synchronous.But these factors are not fully considered in current researches.So a calibration system with digital output is proposed in this paper.Precision and dynamic range are guaranteed by A/D converter with 24 resolution and synchronization error limit is nanosecond by using the novelty synchronization method based on the routed sample clock.To verify effectiveness,error calibration was carried out in the State Grid Electric Power Research Institute of China and results show that the proposed system can reach the precision class up to 0.05.Actual calibration shows that the system has high-accuracy and strong antiinterfere ability.关键词
