OPT100 DGA Monitor

♦   Installation and commissioning in as little as two hours
♦   Continuous operation with roughly one-hour output interval - no data averaging needed
♦   Browser-based user interface to easily view and share data, and change settings
♦   Self-diagnostics with self-recovery after disturbances

There's nothing worse than an unplanned outage, in terms of both lost revenue and the incalculable costs to your reputation and brand. The good news is that over 50 percent of power transformer faults can be detected with the right online monitoring tools, meaning that severe failures can be prevented. But monitors that give false alarms or require regular maintenance can end up wasting considerable amounts of your time and money.

The IR sensor is based on Vaisala core measurement technology and components manufactured in our own cleanroom. Vacuum gas extraction means no data fluctuation due to oil temperature, pressure, or type, while hermetically sealed and protected optics prevent sensor contamination. Moisture is measured directly in the oil with our capacitive thin-film polymer HUMICAP® sensor, which has been used for transformer monitoring for 20 years. Hydrogen is also measured directly in the oil with the same solid-state sensor technology used in the Vaisala MHT410.

Stainless steel pipes, IP66-rated and temperature-controlled housing, as well as a magnetic drive gear pump and valves mean superb performance and durability - from the arctic to the tropics. What's more, there are no consumables to service or replace.

Vaisala Optimus™ DGA Monitor has a web-based user interface that completely eliminates the need for additional software. The device is designed to be installed in less than two hours - just connect the oil, power, and data connections, and it's ready to go. It can be connected to an existing control and monitoring system via digital communication and relays, or used as standalone monitoring device. And in case of a disturbance like a power outage, self-diagnostics allow for self recovery.
