SF6 Density and Moisture Online Monitoring System (Winfoss-S6)

Original imported sensors for precise measurement and long service life;

Patented sealing technology for zero leakage, absolutely ensuring the safety of high-voltage equipment!

Product Overview

The SF6 Density and Moisture Online Monitoring System (Winfoss-S6) allows users to conveniently access and understand the operating status of substations anytime and anywhere. Maintenance personnel can clearly know what they need and what to do. The core of this technological achievement is attributed to the moisture measurement and analysis algorithm based on DRYCAP® detection technology and the digital SF6 gas density monitoring technology. Combined with digital signal processing (DSP) and real-time database technology, it forms an expert diagnosis system. It ensures that the dynamic changes in digital pressure and moisture monitoring data accurately reflect the trend of gas quality deterioration inside the switch, providing a scientific basis for users to carry out condition-based preventive maintenance.+
