Intelligent Calibration and Report Generation of Optical Current Transformers

Abstract

With the development and advancement in power systems and smart grids our metering should be advanced and accurate. For the better protection of power systems the conventional current transformers have been replaced by OCTs and FOCT (optical and fiber optical current transformer) as comparatively they give precise and error free measurements. For analyzing errors and the accuracy of the measuring systems we need an efficient and digital calibration systems through which we can do error analysis of transformers and can check their accuracy. In this paper we have designed a LabVIEW based intelligent calibration systems for the error analysis of transformers. A simulation based which is not effected by environmental interfering, calibration system is proposed in which the accuracy of OCT is analyzed by comparing it with the standard referenced transformer.
