Technical requirements
Transformer online monitoring and fault diagnosis technology is of great significance to improve the safety and stability of the power system.The online monitoring technology based on the analysis of dissolved gases in oil is the most common and most important technology in online monitoring of transformers. The analysis of the composition and content of dissolved gases in oil is one of the most effective measures to monitor the safe operation of oil-filled electrical equipment.The use of photoacoustic spectroscopy to analyze dissolved gases in oil to monitor the operation of oil-filled electrical equipment has the characteristics of maintenance-free, high real-time and high precision.
