WATCH OUR EXPERT WEBINARS Watch the video Maintenance free monitoring with the Vaisala Optimus™ OPT100 DGA -EN Rethinking DGA — Optimus™ OPT100 Our flagship DGA monitor, the Optimus™️ OPT100 is the ultimate choice for your critical transformers. We have rethought transformer monitoring and DGA. We wanted to reduce sampling to a minimum. To go fully online and enable 24/7, always-on monitoring. So you can see more than a sampling-type spot check could —uncover trends and gassing patterns in your critical equipment. We didn’t stop there. We did away with gas cylinders, and in fact, all consumables. The end result is truly zero-maintenance monitoring technology. GET TO KNOW THE OPTIMUS™ OPT100 Better know better Transformers across the world employ well over 10.000 Vaisala probes to monitor for moisture. Why? Because of the uniquely robust HUMICAP® sensor. Proven over 20+ years in service in the harshest environments on Earth — and Mars. Famous for its outstanding measurement performance. In fact, individual probes have come back to Vaisala for calibration checks after 10 years in service, without any maintenance, and upon calibration their sensors were still within their initial accuracy. That’s robust technology. SUPERIOR MOISTURE MEASUREMENT Advanced. Robust. Reliable. Vaisala. A multi-gas DGA monitor, like the Optimus™ OPT100, is your best choice for critical transformers providing a comprehensive understanding of the condition of your transformer. A single-gas monitor like our Moisture, Hydrogen and Temperature Transmitter MHT410, is an unbeatably robust early warning indicator of a fault condition. Revolutionary, robust DGA: OPT100 • The world’s first DGA monitor requiring no consumables • Track the seven key fault-gases at all times • Gain a comprehensive understanding of your transformers’ condition • Now with total gas pressure — ambient air ingress detection Read more Key measurements online: MHT410 • Unbeatably robust single-gas monitor • Early warning indicator of a fault condition in your transformer • Ultimate connectivity and remote monitoring when coupled with the Indigo520 transmitter. • Easy to install Read more The true standard for moisture in transformers: MMP8 • 20+ years proven track record • The true standard for the whole industry • Light and robust • No sampling, no pumps • Always on • Can even be installed in an energized transformer Read more Moisture in transformers Q&A eBook The definitive eBook on the subject, this companion to our four-part webinar series is full of the latest practical and scientific advice on measuring moisture in power transformers.
