МULTIFREQUENCY PROTECTING METHOD AGAINST EARTH-FAULTS OF PHASE IN THE COMPENSATED ELECTRIC NETWORKS
Electrical engineering & Electromechanics, 2020 Introduction. A significant proportion of earth faults in 6 - 35 kV networks is a transient and short-lived process, which is followed by an electric arc. Problem. In such cases, earth-fault protection that responds to steady-state current and voltage is

Multi-point Synchronous Protection Scheme for Active Distribution Network Based on 5G Communication
Zhongguo dianli, 2023 The linear section location method based on remote signaling data does not consider the influence of communication time-delay and reliability, and is only applicable to large current faults and single faults.
