This master thesis work develops the acquisition codes for the execution and post-elaboration of standard tests on induction motors. The aim is to create a tool using the open-source programming language Python. This replaces an already existing Visual Basic application which operation is problematic with the most up-to-date Windows operating systems. The tool is divided in two parts: the former allows the user to remotely control the power meter used for executing the measurements. The latter instead elaborates the test results and determines the parameters of the steady-state equivalent circuit of induction motors. In the last part of the work the tool is successfully used in the lab for performing the standard tests on three different induction motors.
