sf 6 Gas Insulated Equipment | Vaisala

The DPT145 provides an excellent assessment of the sf 6 insulation. Both sudden and minor leaks are detected by the direct normalized pressure measurement, while online dew point measurement alerts the user to moisture issues, which can weaken the insulation properties of Sulfr hexafluoride and cause rapid deterioration.
