Magazine | Issue 1 2025 tests, are covered. Finally, the results of one measurement session, e. g., during FAT or SAT, are summarized in a customizable report. This unified testing approach that supports on-site measurements can also be performed during the power transformers’ manufacturing process. The ability to Pre-dine every measurement step with testing templates allows users to set up an efficient and reproducible testing workflow. Furthermore, factory results can easily be shared with on-site personnel as a comparison reference. TESTRANO 600 and PTM provide an efficient, comprehensive, and reliable solution for power transformer testing. By offering a wide range of diagnostic measurements and the ability to perform three-phase testing, the TESTRANO 600 significantly reduces testing time and effort. The PTM enhances data management and team collaboration, ensuring consistent and thorough testing processes. This unified approach benefits the manufacturing process and on-site measurements, facilitating a streamlined and reproducible workflow that ensures the integrity and reliability of power transformers. measurements to vibro-acoustic measurements (VAM). Since testing time is often a crucial factor during manufacturing, TESTRANO 600 allows users to perform three-phase measurements, such as winding resistance, saving up to 66% of testing time compared to conventional single-phase testing. Additionally, the TESTRANO 600’s connection concept is designed for minimum effort when connecting the test object with a large power transformer or small distribution transformer. «TESTRANO 600 allows users to perform three-phase measurements, such as winding resistance, saving up to 66% of testing time compared to conventional single-phase testing.» When implementing a data collection strategy, storage and exchange are key to establishing efficient cooperation with teams tasked with performing measurements and assessing the condition of an asset under test. PTM eases these tasks with a database approach, allowing users to feed the system relevant information about the asset location, e.g., substation information and nameplate data. Consequently, all measurement results are linked to the asset, which allows users to easily obtain a testing history overview. The results of a single measurement session can be summarized in a customizable report. A corresponding PTM file with all relevant metadata about the location and asset can be exported and exchanged with various parties involved in a test. This also enables testing templates to be created, ensuring that all measurements are performed similarly. Further diagnostic measurements, such as sweep frequency response analysis (SFRA) or dielectric response measurements that can be conducted using FRANEO 800 and DIRANA are included in the overall test report to complete the testing scope. Additionally, manual task templates, such as inspection 41
