Měření na asynchronním stroji, laboratorní úloha.

Abstract

This thesis deals with the development of an application for laboratory measurement of induction machines. Based on technical standards as the basis for understanding the process of measuring and testing principles of induction motors, a set is designed to measure the three types of electrical tests. By measuring the open circuit we learn the dependencies of current, losses and the power factor of no-load power at the input voltage. When short-measuring, we find out, depending on the supply voltage, the current, the losses and the power factor of short measurement. By the load measurement we find out the power factor, efficiency and the slip of performance. The programme for this measurement is generated thanks to the graphic programming using block diagrams in the development environment of LabVIEW.
