The Hydran 201Ti is a small on-line early warning transmitter. It is permanently mounted on the transformer and will provide personnel with a single reading in ppm of a composite value of various fault gases to alert them to a potential issue.

This value can be downloaded and alarms can be set at pre-determined levels to alert personnel and enable monitoring of the developing fault condition.

The Hydran M2-X is the next generation of the field-proven family of Hydran DGA monitoring solutions, providing continuous monitoring of gas and moisture levels to alert users of developing faults and minimize the risk of unplanned outages. The M2-X builds on GE Vernova’s strong domain expertise to deliver an optimized, low maintenance monitoring device with extended sensor life.

The Hydran M2-X is also available in a UL certified, HazLoc version (part number: M2-X-HZ) for installation on transformers located in hazardous locations designated as Class I, Division 2

Gas Insulated Substations have become more frequent sites due to their  reduced footprint and high reliability of operation. But this reliability can be undermined by the presence of free moving metallic particles originating from breaker operations or mechanical vibrations. These particles can generate high electric fields locally initiating partial discharges (PD) within the insulation. Repeated partial discharges will eventually produce a flashover necessitating shutting down the GIS for repairs.

With worldwide scrutiny on SF₆ gas usage, increased environmental reporting requirements and even possible penalties, precise early detection of small gas leaks in Gas Insulated Substations that use so much SF₆ is essential.

The BWatch uses the latest generation of EMC resistant digital gas sensors to continuously measure gas pressure and temperatures in order to track changes in density and detect gas leaks down to 0.1% per year.

GE Vernova’s CBWatch is a compact, modular, online monitoring solution suitable for high voltage circuit breaker. It records information using non-invasive sensors and performs local real time monitoring of operational parameters attached to key breaker functions. It looks for threshold breaches, warns of any significant change in operating performance and assembles an overall condition assessment of the breaker.

Dissolved Gas Analysis (DGA) and moisture measurement of insulating fluids are recognized as the most important tests for condition assessment of fluid-insulated transformers. Every year asset owners deploy field crews to take thousands of fluid samples from transformers as part of periodic health checks and for immediate operational decisions. These samples are sent to off-site laboratories for analysis. The Kelman™ Transport X² is a portable ‘lab in a box’ device.

The MINITRANS is a low-cost on-line discrete multi-gas DGA transformer monitoring unit.

Based on the same core technology as the highly successful TRANSFIX, the MINITRANS is a lower cost alternative, monitoring three key gases: Hydrogen, Acetylene and Carbon Monoxide (in ppm) plus moisture in oil (%RH & ppm). The measurement of these gases allows the user to detect a wide range of developing faults including arcing.

Automated five Gases plus Moisture Online DGA

The Transfix™ DGA 500 is an on-line monitoring unit that measures five individual dissolved gases and moisture, and provides both on-line monitoring and key exploratory diagnostics. It uses GE Vernova’s advanced Photo-acoustic spectroscopy (PAS) technology, made popular due to its accuracy, repeatability and lack of consumable through its bigger brother the Kelman™ Transfix.

The Kelman DGA 900 MULTITRANS is the next generation 9-gas on-line transformer multi gas DGA (Diagnostic Gas Analyzer) monitor. Built from the DGA 900 platform, the Multitrans extends the capability beyond measuring a single transformer main oil tank.

The Kelman DGA 900 TAPTRANS is the next generation 9-gas on-line transformer multi gas DGA (Diagnostic Gas Analyzer) monitor. Built from the DGA 900 platform, the TAPTRANS extends the capability beyond measuring a single transformer main oil tank.
