New 50-page technical white paper on laser photoacoustic spectroscopy (L-PAS) for online DGA of transformer oil — technology fundamentals, detection limits, system architecture, diagnostics, and economics. Free instant download.
Dissolved gas analysis is not an academic exercise. Behind every gas concentration measurement and Duval Triangle plot, there is a transformer — often worth millions […]
For most of the 20th century, transformer maintenance followed a simple rule: open it up every N years, inspect, replace whatever looks worn, and hope […]
Choosing an online DGA monitor involves more than comparing purchase prices. The purchase price typically represents only 30-40% of the total 10-year cost of ownership. […]
Dissolved gas analysis has evolved through four distinct technology generations over the past 50 years. Understanding this evolution helps explain why Laser Photoacoustic Spectroscopy (LPAS) […]
The Duval Triangle is the most widely used DGA interpretation method — but it is not the only one, and relying on a single diagnostic […]
Two major international standards govern dissolved gas analysis interpretation: IEC 60599 (European/international) and IEEE C57.104 (North American). While both aim to achieve the same goal […]
Offshore wind farms represent the most demanding environment for transformer monitoring — and the highest-stakes application. A transformer failure on an offshore platform can mean […]
Every power transformer contains thousands of liters of insulating oil. When this oil is subjected to thermal or electrical stress, it decomposes — releasing a […]
Hydrogen is the first gas produced in most transformer faults. Learn how continuous DGA monitoring can detect incipient faults weeks before they become critical.
