Online monitoring system for power transmission network high voltage cable

In recent years, with the rapid development of the power grid, more and more cables are applied to the urban power grid. As the cable lines become larger and larger, a severe problem is exposed increasingly - - cable line fault. Cable tunnel explosion proof, waterproof, anti gas, security issues become more and more important, in order to meet the needs of cable tunnel "anti five" requirements, must monitor the operation environment of cable, earlier detect the problems and timely deal with,avoiding the occurrence of major problem.
