Study of Magnetic Field produced by 63kV Transmission Lines

Magnetic Field (MF) is produced by Electrical Currents (ECs). In order hand, when Electrical Current increases, MF increases too. Many researches show that MF can have harmful effects on humans and can disturb communications and electronics systems. Transmission Lines (TLs) are Known as major sources of MF due to their ECs. TL can produce strong MFs around itself. So, many people that live near the TLs are concern about the effect of MFs. In this paper for calculation of MF around the TLs a new software package is developed in MATLAB. By using this software package MFs of TLs can calculated in arbitrary point around the TLs. So, safe margin around the TLs can determined easily using the results of prepared software.
