1. Product Title

GE HYDRAN M2 – Online Transformer Monitoring Device (DGA & Moisture Analyzer)

2. Product Overview

The GE HYDRAN M2 is an advanced online transformer monitoring device designed to continuously analyze dissolved gases and moisture levels in transformer oil. It plays a critical role in early fault detection by identifying abnormal gas generation caused by insulation degradation, overheating, or electrical faults.

The HYDRAN M2 provides real-time condition monitoring, allowing operators to detect developing issues before they lead to transformer failure. By measuring key fault gases and moisture content, it enables predictive maintenance strategies and extends transformer lifespan.

Compact and easy to install directly on transformer valves, this device eliminates the need for complex sampling systems, making it an efficient solution for modern power utilities and industrial substations.
