Sažetak
Power losses mainly refer to the heat generated in cable conducting parts (phase conductors and sheaths). Heating power in phase conductors and sheaths depend on current values. A mathematical model of heating power calculation in three phase single-core cable conductors and sheaths is developed. Sheaths are bonded and grounded at both ends. Calculation results for cables in flat configuration show that heating powers in cable sheaths do not have equal magnitude and increase with distance. In some cases heating powers in sheaths could be greater than heating powers in phase conductors.
