Abstract

Изобретение относитс  к области электротехники, в частности к средствам контрол  и измерени  токов в многофазных электроустановках. Цель изобретени  - расширение области использовани  устройства. Дл  достижени  цели магнитодиоды 2-4 размещены в поле проводника с током каждой фазы 5, 6, 7 электроустановки. Магнитодиоды 2-4, соединенные между собой согласно-последовательно, крайними выводами соединены с входами дифференциального усилител  1. Кроме того, второй вход усилител  1 соединен с шиной 8 питани . 1 ил.The invention relates to the field of electrical engineering, in particular, to means for monitoring and measuring currents in multi-phase electrical installations. The purpose of the invention is to expand the field of use of the device. To achieve the goal, magnetodiodes 2-4 are placed in the field of a conductor with a current of each phase 5, 6, 7 of the electrical installation. The magnetodiodes 2-4, interconnected in succession, are connected to the inputs of the differential amplifier 1 by extreme ends. In addition, the second input of the amplifier 1 is connected to the power supply bus 8. 1 il.
