TJ|H2b Analytical Services operates as a full-service laboratory focused on analytical testing and diagnostic evaluation of oil- and gas-insulated electrical equipment, supported by a global network of laboratory locations. The company also performs environmental testing for hazardous materials used in high-voltage equipment, applying a broad set of physical, chemical, and electrical testing methods to inform routine and investigative analyses. By examining samples, it provides insight into the condition of the material and the equipment or site from which the sample originated. TJ|H2b has developed three proprietary diagnostic evaluations for different types of high-voltage equipment: Breaker Oil Analysis for oil-filled circuit breakers, Tap Changer Activity Signature Analysis for on-load tap changers, and Transformer Condition Assessment for oil-insulated transformers of any size, complemented by specialized SF6 sampling and testing procedures to reduce breaker maintenance costs. Based in Sacramento, California, the firm positions itself within the utilities sector as a mid-sized laboratory that also hosts TechCon North America annually to disseminate training and education for industry professionals.
