（1）Training objectives

Watch the demonstration project, and students will observe whether the parameters of the protector and the wire match their physical perception, to let them know the importance of configuring a protector that matches the configuration, as well as the related hazards of not selecting the protector correctly.

（2）Equipment composition: power supply and control power supply, power protection module, data acquisition module, analog voltage display module, overload sensing table, computer, test display module, LCD TV, etc.

（3）Project Function

Functional requirements:

1The protector and conductor parameters do not match the body inductance. When the selected copper (aluminum) wire does not match the protector, the protector will not operate after overload, and eventually the copper (aluminum) wire will burn off and catch fire;

2Replace with a matching protector, which can trip correctly when the wire reaches overload.
