Transformer Monitoring and Diagnostics
Kelman TRANSFIX - eight gas online DGA-monitoring unit for transformers.
Need to know condition of transformers in electricity networks is increasing when transformers are ageing. Up to date and accurate monitoring data is needed in particular from large and critical transformers. Such transformers are usually located in the transmission networks, heavy industry and power generation.
Analysis of a transformer oil sample by a laboratory is an established technique recognised as the most important test for monitoring power transformers. It has long been accepted that Dissolved Gas Analysis (DGA) of oil is the single most powerful tool in the field of transformer fault detection and asset management.
GE’s line of Kelman, Hydran and Intellix products, now has a comprehensive offering of portable, on-line products and software for management of critical transformer assets. With these units transformer faults can be detected in their infancy, minimizing costly unplanned outages and equipment failures.
Single Gas DGA products
Single gas DGA products provide gas level alarm or real-time single composite fault-gas and moisture in-oil measurement to alert persons about a potential issue. Products are easy to install on a single valve.
Hydran M2 - a compact affordable all-in-one on-line transformer-monitoring device.
Single gas products in short:
- Intellix GLA 100 is a small, intuitive and easy to install fault gas level alarm that provides a low cost warning solution to extend DGA monitoring to the smaller lower end transformers in your fleet.
- Hydran M2 is a affordable, compact, real-time fault gas and moisture monitoring device that provides alarms when pre-set limits are reached and communicates data back.

Multiple Gas DGA products
GE's multiple gas DGA products consists of Kelman products, which are based on advanced Photo Acoustic Technology (Photo-Acoustic Spectroscopy). The key benefit of this technology is ability to measure levels of each fault gas separately.
Photo Acoustic Technology does not require calibration of the system or using carrier or calibration gases. This gives remarkable benefits and savings on operating and maintaining these units.
