Products
The new generation of micro-water on-line monitoring system (IED) is one of the basic monitoring unit of intelligent transformers, and has a remote automatic calibration function. This series of transformer chromatographic micro-water on-line monitoring system for the power transformer oil dissolved gas on-line analysis and fault diagnosis for 35kV and above voltage levels of power transformers, electric arc furnace transformers, reactors and transformers and other oil-immersed high-pressure equipment The The system uses the principle of gas chromatography to monitor the dissolved characteristic gas in the transformer oil. The HC series capacitive sensor micro-water detection unit is used to monitor the micro-water content of the transformer oil continuously. It can provide high-precision quantitative analysis, Large oil-filled equipment running state; able to analyze long-term accumulation of monitoring data to determine the status of the monitoring equipment to predict the initial failure of equipment.
