Transmission of the electric power is accompanied with generation of low - frequency electromagnetic fields. Electromagnetic compatibility studies require that the fields from sources of electric power be well known. Many of these sources are not defined to the desired degree of accuracy. This applies e.g. to the case of helical current conductors of finite length. The paper presents an analytical-numerical method of the calculation of the 3D magnetic fields in vicinity of conductors having helical structure. The method is based on the Biot-Savart law and a software tool to model the magnetic fields generated by e.g. twisted wires, helical coils, etc can use the formulas obtained.
