This is the equipment used in achieving electricity-net time synchronization and establishing time measure, and it was developed and accomplished according to the demand and real situation of electricity net. Now it is used in Sichuan Electrical Power Attemper Center, Regional Electrical Power Attemper Center, rundle water and electricity station attemper center, firepower/waterpower plant, centralize control station, switch station, 500kv station and so on. Besides Sichuan, it is also used in Beijing, Shanghai, Chongqing, Hebei, Shangdong, Hubei, Hunan, Jiangsu, Guangdong, Qinghai, Yunnan, Guizhou, Guangxi, Tibet and so on.

Time (synchronization) Precision
≤1μs （1PPS signal）
≤30μs （1PPM signal）
≤10μs （IRIG—B non-modulation code, reference code element relative to 1PPS signal’s front edge）
≤30μs （IRIG—B modulation code reference relative to IRIG—B non-modulation code）
Serial Interface: RS232C, RS422
Time information up to 1ms (year, month, day, hour, minute, second, millisecond)
