TESTING OF ELECTRIC MACHINES IN INDUSTRIAL ENVIRONMENT USING A DATA ACQUISITION AND PROCESSING SYSTEM

Abstract

The paper presents some significant aspects concerning testing electrical machines, including high power ones, using a Data Acquisition and Processing System (DAPS), based on a PC compatible microsystem. There are described the main measurement tasks of DAPS in electrical machines testing, in various functional conditions: constant frequency steady state (used in classical standard tests), variable frequency conditions (used in asynchronous motors testing by mixed frequency method) and finally, transient conditions. Some experimental results, obtained by the authors in the framework of scientific research and consultancy activities, in industrial environment for high power machines, are finally shown as examples. These electrical machines, as single units or small series, have been designed and built by “Electrical Machines Building - Reşiţa”, the only Romanian producer of high power electrical machines used in power systems).
