The device can simulate three main transmission impairments in the factual transmission of fiber optic channel,channel delay,channel bit error,channel interruption,provide a convenient instrument to check and measure the protections’performance of relay equipment with the above three impairments.
介绍了研制的线路纵差保护光纤通道模拟装置,该装置可以模拟光纤通道实际传输中主要的3种损伤:通道延时、通道误码和通道中断,为检查继电保护设备在通信通道的各种传输损伤下的工作情况和指标测试提供了方便灵活的手段,解决了光差保护在开发、检测、试验中缺乏对通道性能考核手段的难题。
