Magazine | Issue 2 2019 The Wilson Transformer Company (WTC) was founded in 1933 in Melbourne, Australia, and is a leading specialist in the delivery of transformer solu- tions. Liam Arnold is a Testing Engineer at WTC and respon- sible for providing operational support for the testing depart- ment. His role includes tasks such as the integration of new equipment into WTC’s existing processes, running improvement projects as well as trouble- shooting equipment faults. When quality and accuracy matter “As a transformer manufacturer, we carry out factory acceptance testing (FAT) on all the transformers built in our factory as required by standard and special cus- tomer requests”, says Liam Arnold. “As FAT are carried out at the end of the production line, we must ensure that the tests run on time so that we can meet the dispatch date.” The FAT results are part of the contractual guar- antees required by their customers. They become the base- line reference for the rest of the transformer’s life-cycle, so the quality and accuracy of the results are critical. “TESTRANO 600 has replaced three different single test sets to perform ratio, resistance and power/dissipation factor tests. With the CP TD1 accessory we also perform power/dissipation factor tests. Hence, when our existing tan delta equipment had reached the end of its life cycle, we were looking for a test set to replace it. The features that drove us to select TESTRANO 600 + CP TD1 included the ability to perform resistance and ratio measurements, three phase testing, demagnetization, frequency response tests for stray losses, digital storage for test results and the level of local support that was available for it. Using a single test system for multiple tests helps us save pack up and setup time. Having the capability to control the tap changer, and getting results automatically also improves our efficiency substantially. We usually use the Primary Test Manage (PTM) software as it enables us to easily collect and manage the test results. Once a test is completed, the data is compared with anticipated values that are based on the transformer design. Afterwards, all the data is exported from PTM into our existing management system,” he finally notes.
