Insulating Fluid & Gas


POLYCHLORINATED BIPHENYL (PCB) TESTING

Though the manufacturing and sale of PCBs has been banned since 1977, these persistent organic pollutants are still found in many pieces of electrical equipment in service today. Due to the chemical stability of PCBs, they are known to accumulate in the environment and food chain. It is required by law to avoid and report release of PCBs into the environment. Powertech can help determine concentrations of PCBs before disposal of equipment or oil, after an accidental spill, or to help you meet in-service equipment regulations.

OIL QUALITY TESTING

A combination of electrical, physical and chemical tests are performed to measure changes in the electrical properties, extent of contamination and the degree of deterioration in the insulating oil. The results are used to establish preventative maintenance procedures to avoid costly shut downs, avoid premature equipment failure and to extend the service life of the equipment.

EVALUATION OF TRANSFORMER SOLID INSULATION

Analysis of paper insulation for its DP value requires removal of a few strips of paper from suspect sites, which can conveniently be carried out during transformer repairs. The results of these tests will be a deciding factor in rebuilding or scrapping a transformer.
