TransVolt is run by a chartered transformer engineer, so the same person who writes your specification can witness the factory tests, test the unit on site and interpret the results.
For owners, developers, ICPs and contractors who need an expert view on a transformer without the overhead of a large consultancy.
Ratings, impedance, losses, cooling, tap changer, protection and testing requirements written to IEC 60076 and your network's standards, ready to go to tender.
Review of the manufacturer's design and drawings, then witnessing of routine, type and special tests at the works so you sign off with confidence.
Review of oil analysis, test history and loading to rank your fleet and recommend maintenance, refurbishment or replacement.
Interpretation of dissolved gas analysis, SFRA, dielectric response and PD results, with clear recommendations.
Root-cause investigation of trips and failures, including off-site inspection of the active part, expert reports, grid type-registration support and advice during commercial disputes. See a recent investigation.
Routine and investigative electrical tests on transformers in service, from distribution units to generator transformers, with a written report and recommendations.
Testing can be combined with GlobeCore oil processing on site, so a wet or gassing transformer is dried and degassed in the same outage.
