Electro-magnetic field (EMF)
Calculation of Electro-Magnetic Field EMF) is one of the factors which must be considered during the design process, especially for high voltage transmission lines. It is common that based on those calculations, the designer or planner may determine the Right of Row (ROW) of the power line.
Moreover, the results of simulations prepared in the designing phase can indicate the impact on the environment which ensures that the proceeding solution will not be dangerous for the people and surrounding nature.
The presented software states a tool which allows conducting calculations of EMF around transmission and distribution overhead lines. The results of calculations are presented on graphical charts as EMF distribution.
It is allowed to calculate EMF for 1 circuit line as well as two circuit lines. In each of the cases, ground wires may be considered. Moreover using different cases it is possible to mix and create major examples of power lines where two independent lines interact with each other.
Electro-Magnetic Field is calculated in accordance with the analytical approach described in EPRI Red Book “Transmission Line Reference Book”. The accuracy of these EMF calculations was checked with other commercial software.
Passive loop wire (PLW) and audible noise (AN) distribution
Apart from the EMF calculations there are also added other extra functionalities:
Model of Passive Loop Wire (PLW) intended for mitigation of magnetic field purposes. It provides a possibility to simulate the influence of the passive loop which is suspended below live conductors in span. Magnetic Field is mitigated by means of induced current which flows through the closed-loop.
Audible Noise (AN) distribution around transmission lines. The calculation of Audible Noise is strictly connected with EMF because the level of Audible Noise is another factor that influences on proper line design process. This program allows making calculations in accordance with three different methods determined by three independent authors. EPRI, BPA, and PN-N-01339:2000 (polish standard).
Results of calculations are presented as a cross-section distribution where different curves are depicted and represent different values of indicators.
In combination with EMF calculations designer receives full range of information about environmental impact on surrounding of the transmission line as well as it may indicate building constraints.
