(Summary description)Medium impedance type bus differential protection is widely used in systems of 220 kV and above. Foreign company maternal protection products used in China's power system include ABB's REB103, GE's BUS-1000 and Siemens' 7SS10. Domestic manufacturers' products: PMH-150 (RADSS/S) assembled by Shanghai Relay Factory, JMZ, HMZ, JCMZ series produced by Nanjing Electric Power Automation Equipment Factory, PMH-140 series of Xuchang Relay Factory, PMH of Acheng Relay Factory The -40 series is a medium-impedance integrated circuit bus differential protection of ASEA (now ABB). It has more mature operating experience in 220 kV and below systems, but it is still imported in 500 kV systems.
