Inductive Interference Assessment from 230 kV Submarine and Underground Cable Systems: A Case Study in Southern Thailand

In response to the increasing electricity demand and to ensure long-term energy sustainability in the southern archipelago of Thailand, the country’s national transmission utility has planned a 230 kV submarine transmission project to interconnect the mainland and island networks. The system will employ a two-circuit, three-phase XLPE submarine cable, scheduled for completion by 2028-2029.
