The Hydran M2 is a sophisticated, permanently mounted fault diagnostic device designed for the continuous monitoring of power transformers. As an evolution in the trusted GE Hydran series, the Hydran M2 provides early warning of potential transformer failures by detecting and tracking the evolution of dissolved fault gases and moisture in insulating oil.

This intelligent transmitter monitors key fault gases such as Hydrogen (

), Carbon Monoxide (

), Ethylene (

), and Acetylene (

), providing a composite value that represents the overall health of the unit. Beyond gas detection, the HydranM2 measures moisture-in-oil levels, which is critical for preventing dielectric breakdown and extending the life of the transformer. Its advanced microprocessor allows it to perform complex calculations on-site, providing trend analysis and alarm notifications before a catastrophic failure occurs.

Designed for easy integration into existing SCADA systems, the HydranM2 supports various communication protocols, ensuring that asset managers have real-time visibility into their fleet. Its rugged, maintenance-free design and high-accuracy sensors make it a cost-effective solution for improving grid reliability and optimizing maintenance schedules. By moving from time-based to condition-based monitoring, the HydranM2 helps utilities reduce operational risks and avoid costly downtime.
