Bundled-Conductors Magnetic Field Calculations

In this chapter, for further illumination of the developed approach to mitigate magnetic field associated with high voltage transmission line, bundled-conductors configuration has been scrutinized. Each sub-conductor is separately analyzed and an equation to calculate the total unmitigated magnetic field is achieved from which, angular frequency responsible to generate maximum value of unmitigated magnetic field is set. An approach to calculate the mitigating loop impedance is also established. The applicability of the developed method has been illustrated and effect of mitigation at seven different locations within the right-of-way has been thoroughly investigated. Process of mitigation and variation of the three types of the magnetic fields with respect to each other has been studied and the related figures and Tables are depicted.
