Each transformer must be designed to withstand the most onerous conditions that can arise in service and to ensure that this is true - the transformer must be properly tested.

    Who should attend?
    This workshop is developed for technical personnel who work in the transformer testing facilities, commissioning engineers, maintenance personnel and inspectors of power and distribution transformers.

    Project managers, operational managers and other personnel responsible for purchasing, commissioning and inspecting the power and distribution transformers in industrial and commercial distribution systems, will find this workshop extremely beneficial.

     

    Course Synopsis:
    From generation at source to the point that electricity is delivered to a consumer, transformers are inseparable part of any electrical transmission system. High-level quality assurance must be maintained during the manufacturing process as well as a rigorous testing regime to ensure that a transformer, once in operation, will perform as expected.

    This workshop discusses various types of testing, applicable standards and specifications, testing conditions and safety considerations. It also outlines the transformer testing procedures that may be performed at any standard Transformer Test Station.
