Overview：
Transformer on-line monitoring and fault diagnosis technology is very important for improving the safety and stability of power system.Among them, on-line monitoring technology based on dissolved gas analysis in oil is the most common and the most important technology in on-line monitoring of transformers. DGA is a powerful diagnostic tool to help you understand the health and condition of power transformers and other oil-filled equipment. Analyzing the composition and content of dissolved gas in oil is one of the most effective measures to monitor the safe operation of oil-filled electrical equipment.DK-200P Portable Dissolved Gas Analyzer using photoacoustic spectroscopy to analyze dissolved gas in oil to monitor the safe operation of oil-filled electrical equipment has the characteristics of accuracy,repeatability,maintenance-free, quick response and high precision.
It has pulsed IR source and 8 distinct spectral bands in the mid-IR region defined by narrow band-pass optical filters.High sensitivity is obtained by utilizing the unique microphone technology from Gasera Ltd., Finland. High selectivity is achieved by choosing up to 8 optical filters with narrow spectral bands for target gases as well as interfering gases. Several spectral regions can be used with each gas for minimal cross-sensitivity. Analysis is based on a modified classical least squares fit of sample response to calibration data.Photoacoustic technology allows high sensitivity from short optical path length which has been further improved with novel model-based non-linear compensation. This provides linear dynamic range of over five orders of magnitude.
