Temperature mapping model of cables considering the coupling of electromagnetic and thermal field

Digital Twin, 2023
Background: During cable operation, its internal temperature reflects the actual working condition of the cable. Once overload occurs, its conductor temperature will rise rapidly. Under high temperature conditions, the insulation material is very prone to breakdown accidents, which seriously threatens the safety
