Lesson 15: Induction Motor Testing: Lock-Rotor and No-load ...

1.) Apply rated voltage and frequency with no mechanical load. 2.) Measure current voltage and power. 3.) Uses same test instrument setup as locked-rotor test. Measure I L, V L and P T. Model for No-load test Since I M >>> I fe it is neglected in this test so R fe omitted Measure P NL = No-load power losses I NL = No-load current V NL = No-load ...

STRENGTH OF MATERIALS LAB MANUAL

The tensile test is most applied one, of all mechanical tests. In this test ends of test piece are fixed into grips connected to a straining device and to a load measuring device. If the applied load is small enough, the deformation of any solid body is entirely elastic. An elastically
