Complete transformer fluid analysis complements Analysts Inc.'s full range of analytical services. By employing the program, facilities that operate electrical transformers can rely on one source for all their oil sampling and analysis requirements. These tests confirm the serviceability and condition of the oil in use and let you schedule transformer maintenance to avoid unplanned outages by illustrating the effects of the transformer's operations on the insulating lubricant. They indicate viscosity, water content, and the dielectric strength of the lubricant. Plus, they detect the presence and levels of acids that could promote corrosion and increased oil degradation, color, and interfacial tension.
Analysts can test for PCBs in oil.
Special handling, care and notification need be taken when submitting such samples for analysis. Analysis for oxidation inhibitor content and power factor are also available. Following physical properties tests, dissolved gases are extracted from your oil sample, separated, and then quantitatively identified through gas chromatography. Gases develop through high temperature degradation of transformer oil and other insulating materials. Should a fault be active, the degradation rate can be significant.
