IEEE standards of energy loss measurement method for overhead conductors suggest minimizing the influence of ferromagnetic substances on energy loss measurement of conductors and averting their interference in energy loss measurement of electric power fittings. Finite element simulation was used to estimate and by test verify the influence of through-flow capacities， external ferromagnetic substances and conductor spaces on energy loss measurement of electric power fittings. The results show that the external ferromagnetic substances can give rise to increase in the measured energy loss of electric power fittings； with the rise of conductor current， the ferromagnetic substances can pose a more significant influence on energy loss measurement of the fittings； during energy loss measurement test of line fittings， there should be no ferromagnetic substance within 500 millimeters of conductors. The research discovery helps mitigate the interference of ferromagnetic substances to energy loss measurement results of electric power fittings. |
