Oil lab to avoid transformer failure



Testing transformer oil is a key function and should be built into maintenance programmes, as it speaks volumes about the condition of the transformer itself. WEG Transformers Africa has an oil laboratory at its production facility in Heidelberg, Gauteng, and offers an extensive range of services to transformer owners. The dissolved gas analysis (DGA) test is one of the most important for a customer to conduct, as it provides the first available indication of malfunction within a transformer unit. The DGA indicates the internal condition of the unit and identifies any degradation. The laboratory can perform a range of important routine tests, starting from the “kV” test, which passes current through the oil to test its insulation properties. The water test would then measure the parts per million of water in the oil; as a conductor of electricity, high levels of water become both damaging and dangerous to the transformer’s continued operation.
