| Abstract: |
| Based on the research and analysis of the arc flash protection principle and related standards, and aiming at the applied characteristics and standard requirements of arc flash protection device, the calibration equipment is designed. It mainly includes DSP control unit, light output module, current output module, and switch input module, which can be used to realize the quantitative linkage output of arc light and current and accurately timing the electric arc protection device's action time. The calibration equipment has passed the certification of metrological verification institutions and has carried out laboratory function tests. The test process and results show that the calibration equipment for arc flash protection device can meet the calibration requirements of relevant standards on main technical performance under the laboratory calibration conditions.
