OPT100 Optimus™ DGA Monitor For power transformers Advanced DGA monitoring • Maintenance‑free operation without consumables • Intuitive user experience • Smart analysis tools • Oil sampling with vacuum gas extraction • Long-term measurement stability through autocalibration and IR reference measurement • Total gas pressure detects air leaks without oxygen sensors • Robust mechanics • Easy installation • Manufactured in Vaisala's cleanroom Vaisala OPT100 Optimus™ DGA Monitor is the right solution for safe‑guarding critical transformers in harsh environments. It delivers out-of-the-box performance, eliminates false alarms, and gives you the best long-term stable measurements for all fault gases. Prevent transformer failure Intuitive and smart design There is nothing worse than an unplanned outage. Lost revenue, damage to your reputation and brand – all of it avoidable. Over 50 percent of serious power transformer faults can be detected and severe failures prevented ahead of time with the right online monitoring tools. The web-based user interface eliminates the need for additional software. Optimus™ can be connected to an existing control and monitoring system using digital communication and relays, or used as a standalone monitoring device. And in case of a disturbance such as a power outage, self-diagnostics enable automatic self-recovery. Optimus™ can be installed in less than 2 hours: connect oil, power, and data – and you're set. Vaisala OPT100 Optimus™ DGA Monitor is robust and intuitive to use. With realtime, trouble-free fault gas monitoring – there are no false alarms, no maintenance and no consumables required. Optimus™ is the culmination of decades of experience, extensive research, and it builds on customer needs. Made with the ultimate safety and reliability in mind, ready for the most demanding operating environments. Reliable data – no false alarms Thanks to autocalibration and IR reference measurement, Optimus™ provides reliable gas trending data at all times. Vacuum gas extraction eliminates fluctuation caused by oil temperature or pressure, and the hermetically sealed and protected optics prevent sensor contamination. Moisture and hydrogen are measured directly in the oil with our capacitive thin-film polymer HUMICAPâ sensor and solid-state sensors. The IR sensor is based on Vaisala core measurement technology and components manufactured in our own cleanroom. The result is data you can rely

tank, the majority of the dissolved gases are nitrogen and oxygen, and the proportion of fault gases in the pressure value is negligible. The pressure trend of the dissolved gasses gives a reliable indication of a leak, as nitrogen is the dominant component, and it is not formed or consumed in reactions inside the transformer. DGA diagnostics with Duval Triangles The publicly available and commonly used dissolved gas analysis method for transformer fault diagnostics purposes, Duval Triangles (IEC 60599, Annex B), is available as an optional feature. The user interface displays the...
