| Abstract: | The paper presents the basic principle of three-section type current protection and the microcomputer relay protection principle and requirements of the underground low voltage switch that are used in the overcurrent protection of the underground electric network. It paid special stress on analysing two parts of the software and hardware of the micro- computer protection. It puts forward a protection plan of the microcomputer relay protection of the underground low volt- age switch. |
