Technical information for New technologies expand the performance range of Online-DGA-Systems

Online Dissolved Gas Analysis (DGA) has transformed power transformer monitoring since the 1970s. These sensors, vital for assessing transformer health, initially detected select gases. However, advancements culminated in the 2020s with the HYDROCAL series, allowing multiple gas detection by integrating near-infrared (NIR) spectroscopy, offering a comprehensive and user-friendly solution for detailed gas analysis and enhanced diagnostics.
