摘要
The invention relates to electrical engineering. The aim of the invention is to improve the accuracy of determining the potential gradient in the arc column of an electric arc furnace by using the statistical characteristics of furnace processes. In the device, the process of measuring the potential gradient in the arc column occurs only in the modes of normal arc burning. For this, a second differentiator 4, multiplication element 6, quad 8, first 7 and second 9 averaging blocks, arc current sensor 13, two comparison elements 12, 14, element 2 OR 15 and timer 5 are entered into the device. The measurement method allows to significantly reduce the value of the variance of the measured values and, as a consequence, to improve the quality of the electric mode control. 1 il. with (L with:
