С .целью упрощени измерители (предложеиного устройства расположены так, что ось каждого из них параллельна пр мой, проход щей через Д1ва провода воздушной линии, и на равных рассто ни х от этих проводов.In order to simplify the gauges (the proposed devices are arranged so that the axis of each of them is parallel to the straight, passing through D1A wires of the overhead line, and at equal distances from these wires.
Предлагаемое устройство изображено на чертеже, где /, 2, 3 - провода воздуш:«ой линии электропередач фаз А, В, С соответственно; 4, 5, 6 - индуктивные измерители токов фаз А, В, С соответственно.The proposed device is shown in the drawing, where I, 2, 3 are wires for air: “the first power lines of phases A, B, C, respectively; 4, 5, 6 - inductive current meters of phases A, B, C, respectively.
