Currently, China has achieved certain accomplishments in this field. Relevant literature has designed typical configuration schemes for grounding fault protection in nuclear power plant low-voltage distribution systems. Based on the analysis of domestic and international cases where grounding faults in nuclear power plant low-voltage distribution systems have caused maloperation of transformer zero-sequence protection, the underlying causes have been identified. Furthermore, improvement suggesti

35 kV Distribution Transformers: Core Grounding Fault Analysis and Diagnostic Methods35 kV distribution transformers are common critical equipment in power systems, carrying important electrical energy transmission tasks. However, during long-term operation, core grounding faults have become a major issue affecting the stable operation of transformers. Core grounding faults not only impact transformer energy efficiency and increase system maintenance costs, but may also trigger more serious elec

1 Current Grid StatusWith the continuous deepening of rural power grid transformation, the health level of rural grid equipment is constantly improving, and power supply reliability basically meets user needs. However, regarding the current grid status, due to funding constraints, ring networks have not been implemented, dual power supplies are unavailable, and lines adopt a single radial tree-like power supply method. This resembles a tree trunk with many branches—meaning the lines have numerou

On December 2nd, the South Cairo distribution network loss reduction pilot project in Egypt, led and implemented by a Chinese power grid company, officially passed the acceptance inspection by the South Cairo Electricity Distribution Company of Egypt. The comprehensive line loss rate in the pilot area decreased from 17.6% to 6%, achieving an average daily reduction of lost electricity of approximately 15,000 kilowatt-hours. This project is the first overseas distribution network loss reduction p
