Standard Screen Analysis & Moisture Content  

Water, Sludge and Acid are three of the most destructive agents in your transformer. These contaminants can affect not only the oil, but the paper insulation & windings. Water & acid can cause premature paper degradation shortening transformer life. Sludge can cause severe overheating and transformer failure.

  Tests Include:

Dissolved Gas Analysis (D3612)

This test measures the combustible and non-combustible gases dissolved in the insulating fluid. It can indicate arcing, overheating, insulation deterioration or electrolysis of water.

Power Factor Testing (D924)

Metals in Oil (ICP)

Metal in oil is a diagnostic tool for determining the location of an incipient fault in transformers, regulators and tap changers. Evaluation of metal type and dissolved gas analysis results may assist in locating the problem.

Inhibitor Content (D4768)

Inhibitor slows the natural decay of mineral oil. Proper levels of inhibitor can prevent damage to your transformer insulating system.  UPSI analyzes for both DBPC and DBP inhibitors.

PCB Testing (D4059)

Gas Chromatography is used to determine each Aroclor^® type of PCB as well as the total PCB concentration present in the insulating fluid. Results are reported in ppm allowing for appropriate record keeping, reporting, handling and disposal of fluid and electrical apparatus per EPA guidelines.

Furan Analysis (D5837)

Furan testing determines the quantity of furans present in insulating fluids.  Furan trending can aid in determining the aging rate of the paper insulation caused by degradation of the cellulose.

Other Tests

Viscosity (D445)

Fire Point (D92)

Flash Point (D92)

Pour Point (D97)

Refractive Index (D1807)
