Power Factor (25C and 100C): (D924)

A measure of the dielectric losses in an oil, and hence, of the amount of energy dissipated as heat.. A low value of dissipation factor (or power factor) is good and indicates low dielectric losses and a low level of soluble polar ionic or colloidal contaminants. A high value usually means contamination of the oil and may be useful as a means of quality control and as an indication of oil changes in service resulting from contamination and oil deterioration. The test can be performed at two temperatures as referenced above.

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.
