Available tests

Here are some of the oil analyses we can make for you

DGA - Dissolved gas analysis (ASTM D3612)

Overall evaluation of the condition of the transformer allowing the detection of electrical faults within the latter and diagnosis with respect to the relative quantities of gas in oil.

Dielectric breakdown (ASTM D1816)

Measurement of the oil insulating properties, a very important factor for maintaining equipment's integrity

Physico-chemical tests (ASTM D971, D974, D1500, D1524, D1816/D877)

Comprehensive approach to the assessment of chemical contamination of oils that may cause electrical problems in transformers.

Water content (ASTM D1533)

Presence of water in a transformer reduces the dielectric properties of the oil and also contributes to insulating paper deterioration, which can lead to a reduction in the equipment's useful life.

Interfacial tension (ASTM D971)

Measurement of acidic or non-acid species which can lead to electrical charges in the insulating oil, hence degrading the insulating paper

Acidity (ASTM D974)

Another measurement of species that can lead to electrical charges in oil and also degrading insulating paper.

Power factor (ASTM D924)

Indicator of electrical losses in transformer oil.

PCB content (ASTM D4059)

Ensures equipment meets applicable environmental standards.
