继适用于220kV—500kV 电压的 LFP—901A,LFP—902A 超高压线路成套快速保护和适用于110kV 线路的LFP—941输电线路成套保护分别于1993年、1994年和1995年通过电力部科技司组织的专家鉴定并在电力系统普遍应用之后,于1996年10月5日,由电自院继电保护研究所研制的 LFP—931A 数字式电流纵差保护,LFP—951A 输电线路成套保护,LFP—900系列变电站成套保护等9种继电保护产品又在南京通过了电力部科技司组织
Following the complete protection of LFP-901A and LFP-902A EHV lines that are suitable for 220kV-500kV voltage and complete sets of LFP-941 transmission lines suitable for 110kV lines were passed in 1993, 1994 and 1995 respectively by the Department of Power Technology Department. After expert appraisal and universal application of the power system, on October 5, 1996, LFP-931A digital current differential protection developed by the Institute of Electrical Relay Protection of the Institute, LFP-951A transmission line protection, LFP- 900 series of transformer substations and other 9 types of relay protection products were passed in Nanjing and passed the Department of Power Technology Division.
