Key features of the TWA25A are a six-winding measurement of transformer winding resistances with a one-time cable connection and three-phase or single-phase automatic transformer demagnetization.
The DV-Win software enables control and observation of the test process, as well as saving and analysing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. The software provides additional OLTC (tap changer) verification options by recording the test current during the transitions. The standard interface is USB and RS232 is optional.
