| Abstract: | As internal components in a protective device of a microcomputer were damaged,from angle of reliability,it was hoped that the protective device should not have misoperation as any component was damaged.And at then same time,the device could check up automatically faulty components and give the alarm so that the faulty components could be treated in time and avoided that the protective device refused operation because the damaged components were not treated in time due to faults in equipment or line. |
