Performing electrical measurements on power transformers is a crucial part of the manufacturing process that verifies the system’s integrity. Since factory and site acceptance test (FAT and SAT) results determine whether an asset condition requires further diagnostic evaluation, these measurements must be conducted thoroughly to yield reliable results. At the same time, the manufacturing process runs on a rigorous schedule that must be adhered to. The TESTRANO 600 and the Primary Test Manager (PTM) offer a tailored solution for testing power transformers and sharing data with multiple teams. The TESTRANO 600 is a dedicated power transformer test device that provides a wide variety of diagnostic measurements that can assess any power transformer’s condition. The testing scope covers conventional tests such as turns ratio and winding resistance measurement, in addition to more in-depth procedures like dissipation factor and short-circuit impedance measurements. Furthermore, the on-load tap changer’s condition is assessed using various tools ranging from dynamic resistance (DRM) and motor current STREAMLINED POWER TRANSFORMER TESTING Efficient, comprehensive, and reliable testing with TESTRANO 600 and PTM 40
