The digital relay teleprotection signal to be transmitted by optical fibre or microwave channel is a new digital communication technique. It can be used to transmit multi-signals through one single channel with efficiency, reliability, safety and less interference. In this paper, the principle and application of relay teleprotection signal transmission based on TDM technique is presented and in cooporation with optical fibre and microwave channel, a special multi-functional digital relay teleprotection signal transmission equipment is completed.
