Abstract With the wide application of optical fiber communication technology in power system relay protection, due to the problem of channel, accidents have also occurred, this paper is an accident of channel loop because of the mistakes of operator in the work and defects of protection device in function, it is not found and handled in time during the long operation, when the outside fault is happen, protection device leapfrog malfunction and trigger big electricity cut. through the analysis of accident, to accumulate experience for later operation, to avoid the occurrence of similar accidents, ensure the safe and stable operation of power grid.
