Online Monitoring Device for Dissolved Gases in Transformer Oil Based on Laser Photoacoustic Spectroscopy Technology
General Description:
The GLRoad Transformer Dissolved Gas Analysis (DGA) is capable of monitoring and analyzing nine types of dissolved gases in transformer oil, featuring high measurement accuracy, high reliability, real-time monitoring, and maintenance-free operation.
By utilizing semiconductor lasers and laser spectroscopy technology, the device significantly improves the gas monitoring performance in transformer oil, markedly enhances the detection rate of incipient faults in main transformers, and thus reduces fault occurrence rates and operation and maintenance costs.
Meanwhile, it adopts a targeted optimal design for the common leakage problem of oil and gas circuits to improve reliability, and also has the advantages of no carrier gas replacement required and maintenance-free operation.
