Many utilities are large industrials are turning to online monitoring to safeguard critical assets and ensure plant operations. But online monitoring has its challenges, including delivery of far more data than traditional testing, which makes manual screening of raw monitor data impractical. 

TOA's Monitor Watch option manages and interprets online monitoring data from any manufacturer's monitoring device, delivering high-quality DGA status assessments to operations, maintenance, asset managers and enterprise systems in teal time. TOA handles both lab and monitoring data, providing consistent information in status and diagnostic reports, regardless of the data source. 

Monitor Watch produces high-quality status and diagnostic reports with statistical and graphical summaries for high-voltage equipment experts.

With Monitor Watch and Reliability-based DGA, key personnel can feel confident that notifications of equipment requiring additional or urgent attention are truly critical events. 

Online DGA monitors are sophisticated electronic instruments suspectable to data quality problems. Monitor Watch evaluates noise levels in monitor data output to detect early signed of sensor deterioration or other problems.
