Training purpose:

Watch demonstration projects by demonstrating equipment grounding and installing residual current circuit breakers. Demonstrate the leakage situation of the equipment under different protection methods, allowing students to experience and perceive the harm to people when the equipment is not grounded and no residual current circuit breaker is installed. Display whether there is any grounding sensation or phenomenon of the equipment without leakage protection device; Whether there is any grounding sensation or phenomenon of the equipment when displaying the leakage protection device;

Equipment composition:

Power supply and control, main control board, communication module, data acquisition module, leakage protection device, testing module, control protection, motion sensing platform, computer, LCD TV, etc.

Functional requirements:

Using an electric motor as the demonstration object; The leakage current value can be predetermined or set on site, and the display instrument displays it in real-time. The data acquisition module is capable of synchronously sampling electrical data and displaying it on a computer screen and audio system. The displayed content includes system composition, leakage principle, installation, operation, and fault phenomena, making it easy to observe, experience, and operate. To ensure human safety, do not come into contact with strong electricity; The casing of the electric motor should be insulated and isolated from the test bench to ensure that any leakage from the demonstration motor will not be applied to the equipment casing.
