Polychlorinated Biphenyls by Gas Chromatography: (D4059)

A quantitative technique for determining the concentration of polychlorinated biphenyls (PCBs) in electrical insulating liquids by gas chromatography. As reference in CFR Part 761 federal guidelines and regulations require that electrical apparatus and electrical insulating fluids containing PCB be handled and disposed of through the use of specific procedures as determined by the PCB content of the fluid. The results of this test method can be used in selecting appropriate handling and disposal procedures to comply with federal, state and local guidelines and regulations.

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.
