doi:10.3969/j.issn.1000-1093.2015.07.019

Abstract

Abstract: The shape of electric cable quitely differs from that of straight wire in the process of measuring the magnetic field of electric cable with electrodes in seawater, so it cannot be checked by the models of straight wire. For this question, the formula is improved by analyzing the difference between straight wire and electric cable in seawater, and the original and improved formulas are compared through simulation calculation. Comparison of calculated and measured values shows that the improved formula has smaller error, and it's more applicable to the checking of the magnetic field of electric cable with electrodes in seawater.

Key words: electromagnetics, electrode, electric cable, field measurement, magnetic induction intensity
