Description
Product Overview
The GE HYDRAN M2 is a compact, high-precision dissolved gas-in-oil analyzer (DGA) designed for continuous monitoring of power transformers. Engineered to detect dissolved gases (hydrogen, carbon monoxide, acetylene, ethylene) and moisture in transformer oil, the GE HYDRAN M2 provides real-time health diagnostics to identify early signs of thermal or electrical faults, such as partial discharge or overheating 27. As part of GE’s HYDRAN® series, this device combines patented fuel cell technology with advanced analytics to support predictive maintenance strategies, minimizing unplanned outages in critical power generation, oil & gas, and industrial applications.
