Online efficiency diagnostic of three phase asynchronous machines from Start up data
2009
The Renewable Energies and Power Quality Journal (RE&PQJ)
In this paper a real time efficiency determination of three phase asynchronous machines is described. Such an online tool improves the reliability of the machines and its maintenance costs. There are various methods to determine the efficiency of three phase induction machines. But all of them have in common that they are to inaccurate or they are impracticable. Here, the machine efficiency will be derived from start up data. For that purpose the variation with time of all stator currents and
