About the Biot-Savart-Laplace law and its use for calculations in high-voltage AC installations

Abstract: Several forms of writing the Biot-Savart-Laplace law and formulas obtained using modern methods for calculating magnetic fields are given. It is mentioned that there are inaccuracies in the interpretation of the Biot-Savart-Laplace law. It is shown that in the electric power industry a simple formula based on the use of the Biot-Savart-Laplace law and the experimentally obtained correction coefficients can be used to calculate the magnetic fields produced by alternating currents in the buses and in power lines… Show more

“…В НАО «Торайгыров университет» ведутся работы в направлении решения этой задачи на основе использования герконов -магнитоуправляемых контактов (длиной от 0,7 до 5 см, весом не более 3 г), устанавливаемых на безопасном расстоянии от токоведущих шин электроустановки. Так предложены [1][2][3][4][5][6][7][8][9] и разрабатываются [10][11][12][13][14] защиты на герконах для различных электроустановок. Что касается дифференциальных защит преобразовательных установок (ПУ), то запатентовано девять таких схем.…”
