Diagnostic Services

MVA Diagnostics uses state-of-the-art laboratory test equipment to ensure our customers receive the highest quality data. Another value that MVA provides to our customers is interpreting the data from their results. No single test can be used independently to determine the oil condition. Rather, our experienced personnel will evaluate all the test data and provide you a recommendation and summation of what is occurring both in the oil and the transformer.

Each transformer is unique, so it’s important to customize an analytical testing program based on the type of transformer–Distribution, Substation, Power or GSU Transformer. Our team will help you develop a test package that fits your needs. Below is a list of our fluid testing bundles for mineral oil, natural esters, silicone, and askarel fluids:
