There are many kinds of external phenomena with power equipments running state changing, and one of the important characters is acoustic signal mutation when power transformer would get out of order. But it is difficult to judge the acoustic change degree and describe the failure character scientifically only by human subjective sensation. The acoustic monitoring can be realized with non-contact measurement,...
Aimed at the difficulty of sensors installation in high-voltage (HV) circuit test experiment, a novel image processing based measure is put forward to detect the mechanical parameters. Through the on-off action images were captured by digital camera with the HV circuit breaker switching, the moving contact travel parameter can be calculated from image analyzing. At the meantime, the necessary timing...
A novel method is put forward, which the power meter can be read based on compute vision, and the architecture of remote meter auto reading system is designed. Different with the normal automatic meter reading system that must obtain the value from digital communication interface, the new method recognizes the meter reading utilizing the computer vision technique, it is a kind of non-contact measurement...
