The Kelman Transport X² remains your ideal partner for use inconjunction with GE’s range of single gas online DGA monitors. These units (such as Hydran™ 201Ti and Hydran M2-X) monitor the transformer and raise an alarm when an abnormal level of fault gas is reached or when the rate of change of this gas level increases rapidly so that you can take action and protect your transformer early in the process. Such events often require further investigation before a valid conclusion can be reached. Traditional methods require an oil sample to be sent to alaboratory for analysis. This can be a lengthy process before a diagnosis and related decision can be made. However, with the Transport X², the sample can be taken and analyzed onsite, giving comprehensive diagnostic information in less than 30 minutes. The Transport X² data can then be uploaded and visualized in GE’s powerful Perception software alongside the readings from the online monitor.


In the world of electrical transformers, ensuring their health and reliability is paramount. These silent giants play a crucial role in power distribution, and their well-being directly impacts industries, households, and infrastructure. However, transformers are not immune to the stresses of operation, and over time, they can deteriorate or develop faults. To monitor and maintain their condition, Dissolved Gas Analysis (DGA) and moisture measurement of insulating fluids have emerged as pivotal tests. These tests are fundamental for assessing the health of fluid-insulated transformers. Traditionally, field crews would collect fluid samples from transformers and send them to offsite laboratories for analysis, a process that often entails delays and can hinder timely decision-making.

Enter the Portable Dissolved Gas Analyzer, a game-changer in the world of transformer health assessment. This revolutionary device, often referred to as a “lab in a box,” is designed to perform detailed DGA and moisture analysis on-site with dramatically reduced turnaround times. In critical situations, it empowers asset owners to determine a transformer’s condition on the spot, enabling operational decisions to be made at the earliest opportunity. This guide explores the transformative capabilities of the Portable Dissolved Gas Analyzer, focusing on the keyword “Portable Dissolved Gas Analyzer,” and how it enhances the assessment of transformer health.

The Significance of Dissolved Gas Analysis (DGA)

Dissolved Gas Analysis (DGA) is recognized as one of the most crucial tests for evaluating the condition of fluid-insulated transformers. It involves the measurement and analysis of gases dissolved in the insulating oil within a transformer. These gases are generated as a result of various processes occurring within the transformer, including thermal and electrical stresses, which can indicate potential faults or issues. The composition and concentration of these gases provide valuable insights into the transformer’s health.

Moisture measurement, often performed in conjunction with DGA, is equally vital. Excessive moisture in the insulating oil can lead to reduced dielectric strength and potential damage to the transformer. Both DGA and moisture measurement serve as early warning systems, allowing asset owners to address issues proactively, minimize downtime, and extend the lifespan of transformers.

Traditional DGA Testing: The Challenges

Traditionally, the process of collecting fluid samples from transformers and sending them to offsite laboratories for DGA and moisture analysis presented several challenges:

1. Delayed Turnaround Times:

The time it takes to transport samples to a laboratory, conduct the analysis, and receive results can lead to significant delays in decision-making. In critical situations, waiting for laboratory results can be impractical.

2. Limited On-Site Decision-Making:

Asset owners often had to make operational decisions without the benefit of on-site DGA results. This lack of real-time data made it challenging to respond promptly to emerging issues.

3. Transportation Risks:

The transportation of fluid samples, which may contain hazardous or environmentally sensitive materials, carries inherent risks. Accidents during transportation could lead to spillage or contamination.

4. Costs and Logistics:

The traditional approach involves costs associated with sample transportation, laboratory analysis, and logistics. It can also be logistically complex, especially for remote locations.
