NTC-08.47.1/1 Introduction and diagnostics of faults in three-phase asynchronous motor with squirrel-cage rotor

The unit is designed for studying the operation of the electric motor. It has an electric motor fault simulator.

The basic types of faults in three-phase asynchronous motors which can be studied with use of the simulator:

• simulation of the U-phase short circuit to ground;
• simulation of the V-phase short circuit to ground;
• simulation of the W-phase short circuit to ground;
• simulation of the U-phase winding interturn fault;
• simulation of the V-phase winding interturn fault;
• simulation of the W-phase winding interturn fault;
• simulation of the U-phase winding breakage;
• simulation of the V-phase winding breakage;
• simulation of the W-phase winding breakage;
• simulation of the U and V-phases interphase fault;
• simulation of the U and W-phases interphase fault;
• simulation of the V and W-phases interphase fault;
• simulation of the wrong winding breakage.

Each of the faults is set with a separate tumbler switch. It allows combining several faults simultaneously.

The panel allows to conduct the following experiments:

• Simulation of a short circuit phase on the case.
• Simulation of inter-turn phase winding.
• Simulation of phase winding breakage.
• Simulation of interphase closure of phase windings.
• Incorrect winding connection.

The complete set contains:

• removable module of asynchronous electric motor, pc. – 1;
• fault regulator, pc. – 1.
