This method gives a quantitative determination of 2,6-ditertiary-butyl para-cresol or 2,6-ditertiary-butyl phenol measures the amount of this material that has been added to new electrical insulating oil as protection against oxidation or the amount remaining in a used oil. New mineral oils identified as Type II typically have .3% by weight of this material and in-service oils are normally kept at .08% or greater to retard oxidation and deterioration of oil due to heat, oxygen and moisture.

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.
