Metals-In-Oil: (D5785)

Electrical insulating oil may contain small amounts of dissolved metals derived either directly from the base oil or from contact with metals during refining or while in service from wearing of bearings associated with oil-circulating pumps . Some of these metals when present act as catalysts in promoting oxidation of the oil. This test method is useful for research and to assess the condition of service-aged oils. Its useful in locating potential problems in large transformers which may so up in the dissolved gas analysis initially and manifest itself through the wear metal signature (MIO).

We current support both TOA 3.3c and TOA4 Online version, which is an Internet web-based software. Both versions interpret dissolved gas and insulating fluid test data for power transformers and other liquid-filled electrical apparatus such as load tap changers, regulators and oil circuit breakers.It provides a variety of reports and graphs to support basic testing, condition assessment and maintenance tasks. Automatic dissolved gas analysis and fluid quality analysis employ up-to-date methods which have been mathematically enhanced to account for measurement "noise" often found in DGA data. Trends and rate of changes are also provided for in this analysis. TOA$ reports may be accessed on the internet once a client account has been set up and information stored to this on-line storage file.
