Providing routine and non-routing testing, investigations, applied research, and consultation to the utilities industry for the purpose of diagnostics, condition assessment and life extension. More than forty years’ experience in testing, consultation, and applied research in the chemistry of insulating fluids, gases, and solids used in electrical equipment. Full-service tribology lab for testing lubricating/hydraulic oils, fuels, and coolants.

Areas of Focus

Our chemistry laboratories are equipped with state-of-the-art instrumentation for chemical, material, and polymer testing, focusing on insulating oils and gases, lubricants, fuels and coolants, environmental and materials evaluation. We have significant expertise with characterizing insulating fluids, including traditional mineral oils, environmentally friendly vegetable oils and sulphur hexafluoride (SF6). Our research and development section is considered world-class and focuses on life extension, on-line monitoring and on-line oil purification of electrical equipment. We also have extensive experience in all aspects relating to electrical utilities PCB contamination, including analysis, on-line removal, and destruction with oil reclamation. Other services include extensive capabilities in polymer and material testing including failure analysis. Our materials and polymers testing lab is equipped with modern thermal analysis, rheology, spectrometric, chromatographic, and mechanical testing instrumentation. Powertech’s long history of testing enables us to provide knowledgeable consulting services.
