Description
Product Overview
GE Hydran 201Ti is a continuous on-line Dissolved Gas-in-Oil Analysis (DGA) transformer monitoring transmitter designed to provide early warning of developing transformer faults. It is permanently installed on oil-filled transformers and measures a composite concentration of fault gases, providing operators with real-time condition information.
The Hydran 201Ti is part of the GE Vernova Grid Solutions Hydran family and is designed mainly for small and medium power transformers, where continuous monitoring provides an alternative to periodic manual oil sampling.
The unit uses a Hydran composite gas sensor based on fuel cell technology. It responds primarily to hydrogen (H₂), which is a general indicator of transformer faults, and is also sensitive to gases associated with overheating and arcing conditions.

Main Features and Advantages
Continuous Transformer Condition Monitoring
The Hydran 201Ti continuously monitors dissolved fault gases in transformer oil, allowing operators to detect abnormal conditions before major failures occur.
Typical fault indications include:
- Insulation overheating
- Partial discharge activity
- Electrical arcing
- Oil overheating
- Paper insulation deterioration
Early Fault Detection
By tracking gas concentration and trends, the Hydran 201Ti can provide:
- Early warning alarms
- Gas trend analysis
- Transformer health assessment
- Reduced risk of unexpected outages
