This article is about low-frequency power transmission technology, which is an emerging power transmission technology that has gradually shown technical and economic advantages in typical scenarios such as long-distance and large-capacity power transmission and offshore wind power delivery in recent years. This article will systematically introduce the relevant principles, methods and development trends of low-frequency (20Hz) electric power transformer on-site calibration technology to provide theoretical basis for further improving the accuracy and reliability of low-frequency transformer calibration technology. This article will first introduce the basic principles and application fields of low-frequency electric power transformers, and then focus on discussing on-site calibration methods and technologies, including on-site calibration methods inside stations, on-site calibration methods outside stations, as well as calibration instruments and equipment. Next, it will explore the development trend and challenges of on-site calibration technology, summarize this paper, and look forward to future research directions.
