| Abstract |
Dissolved Gas Analysis is recognized as a power tool for monitoring and diagnosing of power transformer. Power transformer decomposes gases under abnormal operation condition. Among the gases, acetylene is an important monitoring parameter as well as ethylene and carbon dioxide. The current online DGA methods are restricted to problems such as reliability, cross sensitivity, and compatibility. In this paper, gas detection system based on photoacoustic spectroscopy is introduced to detect acetylene, carbon dioxide, and ethylene dissolved in transformer oil. |
