DGA Monitor OPT100
Vaisala OPT100 Optimus™ DGA Monitor is the solution for safe‑guarding critical transformers in harsh environments. It delivers out-of-the-box performance, eliminates false alarms, and gives you long-term, stable measurements for all fault gases.
Product Overview
The Vaisala Optimus™ DGA Monitor OPT100 provides continuous online dissolved gas analysis for power transformers. It monitors key fault gases and moisture in transformer insulation oil to provide real-time information about transformer condition.
The OPT100 uses infrared measurement and vacuum gas extraction technology without consumables such as carrier gases, calibration gases, membranes, or internal columns. The monitor also includes Total Gas Pressure measurement for detecting ambient air ingress into sealed transformer tanks. An optional O2 + N2 measurement configuration enables monitoring and trending of all nine gases.
