| Abstract: | By analyzing the foreign potential CMU(Contro l Monitor Unit), the design defect and limitation such as the small scope of vol tage adaptation, lack of over current protection, and poor visualization are fou nd. According to the factual situation of power supply for domestic factories, t he CMU is improved with the use of conventional electronic devices. The suitabil ity to voltage pulsation is improved and the running stability is also enhanced. A new means used to better domestic under voltage relay is put forward on the basis of the foreign voltage control monitor unit. |
