Lesson D1 – GSENS H2 (Hydrogen DGA Sensor)
GSENS-H2 is an online, real-time Hydrogen-in-oil sensor designed for Dissolved Gas Analysis (DGA) in power transformers. Hydrogen (H₂) is the earliest and most universal fault indicator, making GSENS-H2 a critical tool for detecting incipient thermal and electrical faults.

Gas Sensors

The sensor is engineered to provide accurate multi-gas readings without consumables, making it suitable for utilities seeking cost-effective and maintenance-free DGA solutions. It integrates easily with SCADA systems, RM EYE, and asset performance platforms.

Typical Features include:

  • Simultaneous measurement of multiple fault gases (e.g., H₂, CO, CH₄, C₂H₂, C₂H₄ depending on model)

  • Continuous online monitoring

  • No consumables or calibration gas required

  • Long service life, high stability

  • Robust digital communication outputs

  • Compact footprint for easy retrofit
