GE ENERGY HYDRAN H201Ci-1 Transformer Monitoring Module

This module serves as a critical diagnostic tool for power transformers, offering real-time dissolved gas analysis (DGA) to detect internal faults. It’s commonly deployed in electrical substations, industrial power systems, and renewable energy facilities where transformer reliability is paramount. The HYDRAN H201Ci-1’s ability to measure six key combustible gases plus moisture makes it particularly valuable for predictive maintenance programs.

We’ve seen this module deployed extensively in utility networks for monitoring large transmission transformers. One customer in Texas reported catching a developing fault 72 hours before it would have caused a catastrophic failure – that’s the value of continuous DGA monitoring. It also integrates well with SCADA systems in industrial plants, particularly those using GE’s own VMIVME-7807 modules or UR6UH interface cards. Renewable energy sites, especially wind farms with remote transformers, benefit from its rugged IP66 enclosure and self-diagnostics capabilities.
