Back by popular demand, LumaSense is hosting a webinar, Practical Online DGA Practices and Applications, on May 23rd at 1:00 EDT. This informative webinar is not a sales pitch, but rather informative and explains how continuous monitoring using dissolved gas analysis (DGA) and various interpretation tools allow utilities to get a more complete picture of transformer and LTC health.
LumaSense delivers many innovative temperature and gas sensing instruments for monitoring transmission and distribution assets. From gas monitoring with Non-Dispersive Infrared (NDIR) and Photoacoustic Spectroscopy (PAS) technologies or temperature monitoring with infrared and fiber optics, our broad range of technology expertise allows us to offer industry professionals opportunities to implement cost-effective online monitoring solutions to manage and maintain equipment.
Transformer Winding Hot Spot Monitoring – More than 40 years ago, LumaSense pioneered the field of fiber optic winding hot spot measurements with Fluoroptic® technology. Monitoring with fiber optics enables operators to accurately measure the actual hot spot temperature in real-time.
Transformer and LTC DGA Monitoring – With NDIR-based instruments, operators can perform automated, remote dissolved gas analysis to detect key fault gases and perform analysis on the condition of the transformer or load tap changer.
Substation Asset Monitoring – Infrared tools such as thermal imagers and pyrometers enable utilities to remotely monitor specific connections and assets such as transformers, bushings, and capacitor banks in real-time.
SF6 Leak Detection – Using PAS for SF6 leak detection creates a highly accurate, sensitive, and reliable solution to limit the emissions of insulating gas found in switchgears.
Learn more about these solutions on our website or visit us at the upcoming Middle East Electricity show March 6-8 in Dubai. Talk with our experts and learn more about these technologies at Stand Z3.E17.
During our recent Dissolved Gas Analysis webinar “Understanding DGA Techniques and Interpretations,” Dr. Gregor Hsiao answered a number of excellent questions from attendees. Read on to learn more about these questions and find out how you can watch the recorded webinar!
North America relies on an aging electrical grid, some of which originated in the 1880s. This old and complex patchwork system of power generating plants, power lines, and substations operate cohesively to power homes and businesses.
Age is an important indicator of remaining life and structural strength. As equipment gets older, it breaks down causing an increasing number of power outages. A recent project investigated 2,300 “problem” transformers out of the total US installation base of 115,000 large power transformers. Of these 2,300, a total of 750 failed – for a failure rate of 32%! The industry cost of power interruptions caused by transformer failure can be considerable.
Transformers are the most important (and costly) equipment in an electrical power network. These aging pieces of the system put a difficult choice in front of the world’s electric utility companies: replace the critical transformers with new units or try to extend the working life of the existing fleet of older units.
In our last post, we shared the results from our 2012 transmission and distribution survey and learned that cost is the leading deterrent of wide-scale deployment of an online Dissolved Gas Analysis (DGA) monitoring solution. We also discussed how to make old transformers last longer by making them “smarter” with continuous online monitoring and diagnostics, similar to how we need more frequent blood testing and analysis as we age.
The transmission and distribution infrastructure is under heavy stress and is increasing in age without quick relief in sight. Electrical demand continues to grow steadily every year with utilities unable to financially and physically keep up with replacement and expansion of assets. When you add the much talked about age of the utility workforce with their decades of expertise and knowledge, yet knowing they will be retiring very soon, you see a perfect storm developing. Utilities need to extend the life of their assets, and do so intelligently with automation to also compensate for the retiring workforce and keep up with impending growth.
Brett Sargent will be discussing this issue in technical presentations next month in Calgary, when he begins the “On the Grid with Brett Sargent” tour. Continue reading →
While industry and government cooperate to build out the “smart grid” for the future, we believe it is equally critical to address the ever growing energy consumption happening today by tightening up the energy delivery side to fully leverage existing assets.
Last year, LumaSense surveyed power industry professionals from around the world about their transmission and distribution (T&D) infrastructures as they exist today and needs for the future. Here are a few facts to set the stage:
