近年来,随着昆明电网的快速发展,电力基础设施投入逐年增大,运行维护工作面临巨大压力。随着科技水平的不断发展,目前国内参数采集终端设备的精确性已经能如实反映电缆及环境运行状态。通过实施监测电缆运行电流、护层电流、瞬间故障电流信号、电缆局放信号及分布式
In recent years, with the rapid development of Kunming Power Grid, the investment in power infrastructure has been increasing year by year, and the operation and maintenance work is under tremendous pressure. With the continuous development of science and technology, the accuracy of the domestic terminal equipment for parameter acquisition has been able to accurately reflect the operational status of cables and the environment. Through the implementation of monitoring cable running current, sheath current, instantaneous fault current signal, cable PD signal and distributed
