A quantitative observation of damage on the electrical contact surface is very difficult so far because of no proper measuring system. Therefore, developement of a new measuring system for this purpose is needed for performance estimation of characteristics of electrical contacts. A digital image signal processing technique was applied for this purpose and the experimental results show that the developed system is very useful for quantitative observation of contact surface.
