The Research and Realization of a New Intelligent Transformer Calibrator

摘要

摘要: 通过分析互感器比、角差测量方法,提出并实现了一种基于精密90°锁相移相电路的新型智能化互感器校验仪自动化测量方案。

Abstract: By analyzing sampling method of transformer errors, a newly developed intelligent transformer calibrator is presented. An orthogonal decomposation circuit based on 90° Phase-shift with phase-locked loop is realized. The calibrator can measure the ratio error f and phase displacement δ of both current and voltage transformer automatically.
