Understanding Sweep Frequency Response Analysis and Best Field Practices

A transformer is a complex system composed of various elements including windings, a core, tap changer, bushings, etc. These elements together constitute the transformer and contribute to its proper functioning. Any situation causing a physical displacement of any of those components can endanger the transformer itself. When a transformer is subjected to a fault, the high currents that arise can create tremendous mechanical forces which can cause the windings to deform. Transporting a transformer from the factory to the substation is a tedious task and involves a lot of planning and care. Any physical impact to the transformer caused by an accident can result in internal displacement of components. The Sweep Frequency Response Analysis test enables us to look for these physical changes inside the transformer without having to physically enter the transformer. There are many tests which have been done on transformers for a long time. SFRA is one of those tests which has a relatively shorter history. Hence, there are many questions which people have regarding the SFRA. This webinar will attempt to answer all those questions. Through this webinar, the attendees will get familiar with the theory behind measurements, the test procedure including best practices to get accurate measurements and analysis of results.
