摘　　要：电子式互感器具有体积小、重量轻、频带响应宽、无饱和现象、抗电磁干扰性能佳、无油化结构、绝缘可靠、便于向数字化、微机化发展等诸多优点,是电网发展应用的方向。目前电子式互感器处于现场应用的初期阶段,实际运用中比较电磁式互感器存在缺陷频繁,维护困难问题。通过对电子式互感器运行中发现缺陷的处理,对缺陷原因进行分析,为电子式互感器现场运行维护提供参考及帮助。Electronic transformer has many advantages, such as small volume, light weight, wide band response, no saturationphenomenon, good anti-electromagnetic interference performance, oil-free structure, reliable insulation, easy to digital, computerizeddevelopment and many other advantages. It is the direction of power grid development and application. At present, the electronictransformer is in the initial stage of field application, compared with the electromagnetic transformer in practical application, there arefrequent defects and difficult maintenance problems. This paper deals with the defects found in the operation of electronic transform-ers, analyzes the causes of defects, and provides reference and help for the field operation and maintenance of electronic transformers.
