Neutralization Number or Acidity: (D974)

The neutralization number or acid number of an electrical insulating liquid is a measure of the acidic components of that material. In service-aged liquids, the neutralization number is a measure of the acidic by-products of the oxidation of an oil usually formed by heat, oxygen and moisture. The Neutralization number may be used as a general guide for determining when oil should be reprocessed or replaced as reference in
IEEE C57-106-2006.

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.
