GDSCAN 5000
Hydrogen (H₂) and Temperature Monitor
Dissolved hydrogen and oil temperature monitor for tracking transformer condition and detecting signs of electrical faults.
Description
H2scan's GRIDSCAN 5000 is a “state-of-the-art monitor that integrates multiple sensors into a single device, enabling advanced predictive diagnostics and continuous monitoring of electrical transformers.” Its main objective is “early detection of dielectric faults and prevention of catastrophic events” through precise hydrogen (H₂) and temperature measurement using its patented solid-state technology. The solution promises a “significant reduction in operating expenses (OPEX),” eliminating the need for periodic calibration and minimizing maintenance interventions.
