Abstract

In order to achieve high reliability in electric power service and reduce the maintenance cost, it is necessary to develop on-line monitoring of power transformers. The on-line monitoring of oil-dissolved gas can obtain the operating conditions of transformer in a real-time way. It has become a reliable method to ensure the safe operation of transformers. For transformer on-line monitoring application of the group sensor, which is composed of a CO sensor and a H₂ sensor, is summarized. The intelligent on-line monitor with the group sensor, which can be used to separately detect H₂ and CO, is introduced. The monitor can provide a quantitative analysis of the concentration of H₂ and CO in a real-time way. It shows excellent peculiarity
