Scientific
Online DGA monitor data is inherently noisy. Monitor Watch signal processing cleans the data, making it more useful for TOA’s advanced analytics. Monitor Watch also recognizes phenomena such as data spikes, monitor drift, and seasonality, which may lead to false alarms.
Easy
Quality information presented simply and conveniently makes critical decision-making easier. And knowing the team behind the information is always available to assist provides confidence in making those hard choices.
Independent
TOA with Monitor Watch works with any online DGA monitor. Users can view their entire fleet – regardless of make or model – on a single screen.
Say goodbye to false alarms
Conventional DGA applies simple limits to online monitor data, which produces many false alarms. But with Monitor Watch and Reliability-based DGA, maintenance teams can be confident that notifications of equipment requiring additional or urgent attention are truly critical events. Monitor Watch also evaluates the quality of monitor data to detect early signs of sensor deterioration or other problems, so staff can ensure that the safeguards are working at their optimal levels.
Reliability-based DGA
Reliability-based Dissolved Gas Analysis identifies and assesses power transformer abnormalities by correlating fault gas production with transformer failures.
Who we serve
We provide accurate and timely insights into equipment like power transformers to generation, transmission and distribution utilities, and leading industrial operations around the world.
