When your Dissolved Gas Analysis test results indicate you have an active fault, the next step is to de-energize the transformer and investigate. A full slate of electrical testing, including power factor testing, winding resistance, sweep frequency response analysis testing and other routine tests can help isolate the source of the fault gases. After testing, analyzing the data is critical to determine the next step for the transformer repair. No single test can be used independently to determine the transformer condition. Rather, our experienced personnel will evaluate all the test data and provide you a recommendation and summation of what is occurring with your transformer and your options.
Likewise, after vacuum filling new units, MVA will perform all of the electrical testing so the customer has baseline test results for future comparison, as well as comparing against the factory test results.
