Robust science. Robust results. Vaisala leads the leap into knowledge.
Electricity is a backbone of modern society – no power, no connections. In today's world, being connected is unthinkable even for the briefest intervals.
Vaisala's real-time online measurement transmitters are the choice of utilities & plants that want to safeguard critical assets, prevent unexpected outages, increase performance, and prepare timely maintenance plans.
Our flagship DGA monitor is the ultimate choice for critical power transformers.
We reduced sampling to a minimum. So you can go fully online and enable 24/7, always-on monitoring, see more than a sampling-type spot check could, and uncover trends and gassing patterns. We also did away with gas cylinders, and all consumables. The end result? True zero-maintenance monitoring.
Transformers across the world employ well over 10.000 Vaisala probes to monitor for moisture. Why? Because of our uniquely robust HUMICAP® sensor. Proven over 20+ years in service in the harshest environments on Earth and Mars.
Individual probes have come back for calibration checks after 10 years in service, without any maintenance, but with their sensors still within their initial accuracy. That's robust technology.
Technology that has proven itself in the toughest conditions on two planets. From the arctic to the tropics, to offshore.
We’re a science company at heart. It’s in our DNA to look deeper, and turn discoveries into practical advantages for our clients.
We help make sense of the unseen, uncover trends and deliver actionable information for decision-makers. Read more »
Ensure your power transformer stays operational longer. OPT100 brings unmatched long-term stability, reliability and measurement performance for detecting the formation of fault gases.
The MHT410 works in-situ, measuring directly from your transformer insulation liquid. Your gain? Reliable hydrogen trend reading as well as fast moisture data.
Smart and robust. That’s Vaisala MMP8. Powered by the Vaisala HUMICAP® sensor technology, it has become a virtual standard in its field.
Our uniquely capable Multiparameter Transmitter for SF6 gas opens for you the world of online measurement of dew point, pressure, and temperature. It also calculates four other values, including SF6 density.
Get to know how Vaisala eliminates the effects of drift in DGA through IR reference measurement technology. This video blog has the answers to what drift is, why it matters and what you can do to prevent the effects of drift causing problems such as false alarms and breaks in production.
Vaisala's Senja Leivo and Riku Rantala go head to head to discuss practicalities and real-life lessons learned, and tackle audience questions sent in before and during the webinar.
Filled with your actual questions answered by Vaisala's experts, this nearly 40-page eBook is a versatile manual for anyone whose business it is to maintain guard against and understand the effects of moisture in power transformers.
In four episodes, you'll get a deep dive into both the science and practice of moisture in oil and measuring it, culminating in a two Expert Q&A sessions with your insights & questions answered by the experts.
Infrared technologies, whether PAS or NDIR, are a great option for DGA monitoring. Infrared also makes it possible to create a maintenance-free DGA monitor that does not need any recalibration — if you can solve the challenge of oil aging.
Ever-increasing efficiency targets concern all industries and their assets. Power transformers are no different. Maximizing and extending their lifetime is all about meeting this challenge.
The following case study explores the detection of severe faults and the overall monitoring process and procedure during an old transformer's final months in service - it's end-of-life (EOL).
Download this eGuide now and discover 8 ways of improving your power transformer and high-voltage asset monitoring. Online monitoring helps make better-informed decisions, on-time and on budget.
