Attachment D- Sample Report.pdf

This is Attachment D, a Laboratory Services Summary Report prepared by Infotest for the National Institute of Standards and Technology (NIST) dated November 23, 1998. The report documents comprehensive fluid analysis testing results for 89 silicone and mineral oil-filled transformer units located at NIST's Gaithersburg, Maryland facility (Building 301, Room B-114). Contact information is provided for James W. Crank (301-975-6952, fax 301-975-3841).

The report presents detailed analytical results across multiple test parameters including color, visual clarity, acidity (D974), dielectric value (D877), water content (D1533), IFT (interfacial tension), power factor (D924), specific gravity, PCB content (D1298), and furan analysis (D5837). Test dates range from October 21 to October 28, 1998, with sample volumes varying from 200 to 597 gallons and KVA ratings from 225 to 2500. Results are color-coded to highlight unacceptable levels of required servicing, with yellow shading indicating samples requiring attention. Key findings note that while most samples maintain acceptable fluid quality, several units—particularly serial numbers 3637842, 3637843, and 3637840—show elevated acidity, dielectric values, or water content levels warranting preventive maintenance or transformer servicing. The report includes supplementary transformer inspection analytical reports and dissolved gas analysis reports documenting hydrogen, methane, acetylene, ethylene, ethane, carbon monoxide, and carbon dioxide levels for select units, with individual unit data presented across eight comprehensive pages.
