Power Transformers (≤550MVA)

Wilson Transformer Company’s Power Transformer Business Unit produces customised power transformers ranging in size from 3MVA up to 550MVA 400kV at our Glen Waverley facility. These products form a critical part of the electrical infrastructure in the power generation, transmission and sub-transmission networks and ensure reliable supply of electricity.

Our power transformers are designed and manufactured for each specific customer requirement.  Standard proven design methodologies and extensive simulation tools are both used to prove the product design and ensure superior product performance in the field.  The products are then manufactured in our state of the art facility with the latest technology equipment, systems and processes that are all subject to strict quality control gates.

All transformers are subjected to comprehensive routine tests and specified type tests, in accordance with the customer’s requirements, relevant standards and Company procedures.  All high voltage tests are performed in a Faraday cage test laboratory which is electrically and acoustically isolated from the main assembly building.  Test equipment includes impulse generators rated up to 1,600kV and 160kJ for full and chopped wave impulse tests, partial discharge measurement equipment and precise digital instrumentation for accurate measurement of losses.

Large power transformers are designed and manufactured for specific applications and requirements. Our range includes generator, transmission, and sub-transmission transformers up to 550MVA 400kV, with off-load and/or on-load tap changers.

Medium power transformers are designed and manufactured for specific applications and requirements. Our range includes generator and sub-transmission transformers from 3MVA up to 40MVA, with off-circuit and/or on-load tap changers.
