Providing testing, analysis, investigations, applied research and consultation to the power 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.

Areas of Focus

Our chemistry lab is equipped with state-of-the-art instruments for chemical, material and polymer analyses focusing on insulating oils and gases, lubricants, fuels and coolants, environmental and materials evaluation. Expertise in the areas of insulating fluids and analysis, including traditional mineral oils, environmentally friendly vegetable oils and SF6. The 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 analytical services for environmental testing, fuels, lubes and coolants analysis and extensive capabilities in polymer and material testing including failure analysis. The 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 it to provide knowledgeable consulting services. The company’s in-house developed expert system, called Equipment Health Rating (EHR), uses industry standards and statistical analysis of lab test results, field inspections, and electrical tests to present historical information on the performance of equipment.
