（1）Training purpose:Through personal experience, students can compare the correct and incorrect escape methods when entering a step voltage environment, understand the correct escape methods in step voltage environments, and learn safety skills and enhance safety awareness. During the experience, the device is able to output a safe range of voltage. When the human body walks normally into the step voltage area, there is a clear sense of electric shock, and the closer it is to the ground point of the wire, the stronger the sense of electric shock; When the experiencer walks with one foot into the step voltage area, there should be no perception of electric shock; When the tester enters the step voltage area with their feet together, there should also be no perception of electric shock.

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

（3）Equipment function:

1High intelligence simulation function, based on the distance between the person and the ground point of the wire, the step voltage is designed as8The higher the voltage level, the closer it is to the landing site, and the more obvious the electric shock feeling.

2There are three experience modes: normal entry, jumping with both feet together, and jumping with one foot.

2Safety protection function: The equipment uses voltage and current limiting devices, as well as overcurrent protection, to limit the magnitude of the step voltage applied to the human body, ensuring the safety of the experience personnel.
