Optimus DGA-Monitor OPT100 now with advanced power transformer air leak detection
Product Description
The Vaisala OPT100 Optimus™ DGA Monitor
is a state-of-the-art system for monitoring power transformers in demanding environments. It provides advanced online DGA monitoring, ready to use out of the box, with no consumables and no maintenance required.
Thanks to auto-calibration and IR reference measurement, the OPT100 ensures long-term stable and reliable data. The innovative vacuum gas extraction eliminates fluctuations caused by oil temperature or pressure.
With its intuitive web-based user interface and intelligent analysis tools, the OPT100 can be easily integrated into existing SCADA systems or used as a standalone device. Its robust design prevents false alarms and ensures reliable operation in extreme conditions.
Key Benefits
- Maintenance-free operation with no consumables
- Easy installation in less than two hours
- Long-term stability with auto-calibration and IR reference
- Air leak detection without oxygen sensors
- Web-based interface without additional software
- Rugged mechanics designed for harsh environments
Technical Specification
The OPT100 measures all critical fault gases including methane, ethane, ethylene, acetylene, carbon monoxide, carbon dioxide, and hydrogen in the range of 0 to 10,000 ppmv (for H₂ up to 5,000 ppmv). Accuracy ranges from ±4–15 ppm or ±5–10 % of reading. Moisture in oil is measured with an accuracy of ±2 ppm or ±10 %.
The total gas pressure measurement covers 0 to 2000 hPa with an accuracy of ±10 hPa or ±2 %.
A full measurement cycle takes 1 to 1.5 hours, with initial results available after two cycles and full accuracy after two days. Data storage exceeds 10 years, and the expected lifetime is over 15 years.
The power supply supports 100–240 VAC or 110–220 VDC, with a typical consumption of 100 W and a maximum of 500 W.
Communication interfaces include RS-485 (Modbus RTU, DNP3 optional), Ethernet (Modbus TCP, HTTP, HTTPS, IEC 61850 optional), and three relay outputs.
The housing is made of seawater-resistant aluminum, with the PSU unit built from stainless steel AISI 316. Installation uses Swagelok stainless steel fittings.
