DGA Moisture in Oil Total gas pressure OPT100 MHT410 MMP8 Power industry solutions Robust science. Robust results. Vaisala leads the leap into knowledge. Download our latest eBook Turn your DGA data into Duval Triangles and Pentagon Visualize the state of your power transformer, with Duval Triangles, Pentagon, and gassing trend graphs. Supports IEC & IEEE standards, as well as data import & export. Try the DGA Calculator Cut the guesswork – DGA reimagined Electricity is the backbone of modern society. In today's world, being disconnected from power 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. DGA REIMAGINED. CLICK HERE. Advanced DGA – Optimus™ OPT100 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. GET TO KNOW THE OPTIMUS™ Better know better 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. SUPERIOR MOISTURE MEASUREMENT Why Vaisala Robust.Technology that has proven itself in the toughest conditions on two planets. From the arctic to the tropics, to offshore. Knowledge.We’re a science company at heart. It’s in our DNA to look deeper, and turn discoveries into practical advantages for our clients.
