Abstract: This paper mainly introduces the composition of auto testing device about protection against electric shock. The test system adopts STM32 series micro-processing chip as the main component of peak voltage off module, using sampling and averaging method to automatically calculate the residual voltage. The device can automatically identify frequency and make voltage off and residual energy testing for wide frequency range of AC voltage. The energy test after peak voltage off in the electrical equipment can understand the condition of the equipment of residual energy in time. It can prevent electrical shock to operator, and provide technical support and technical reference for test institutions to carry out product testing and enterprise to develop product.
