Description
ставл ющеи индукции магнитного лол соленоида , имеет также вид концентрических окружностей , но направление его одинаковое на торцах магнитолровода. На фиг. 3 и 4 .показано вихревое электрическое поле наводки ЕлThe magnetic inductor of the solenoid lol also has the form of concentric circles, but its direction is the same at the ends of the magnetic conductor. FIG. 3 and 4. The eddy electric field is shown.

ходе контура: электрод 4, внешн среда, токопровод ща шина, внешн среда, электрод 5 (см. фиг. 5) видно, что сигнал, направл емый в измеритель, складываетс из суммы полезных сиг налов, обусловленных электрическим полем EV у торцов магнитопровода датчПКа , и разности сигналов вихревого электрического пол наводки Ед. При условии полной симметрии картины нол и конструкции индукционна наводка равна нулю, а полезныйDuring the loop: electrode 4, external medium, busbar bus, external medium, electrode 5 (see fig. 5), it can be seen that the signal sent to the meter consists of the sum of useful signals due to the electric field EV at the ends of the sensor circuit , and the differences of signals of the vortex electric field pickup. Under the condition of complete symmetry of the picture, the zero and the design of the induction pickup is zero, and the useful
сигнал удваиваетс в сравнении с сигналом, сн тым у одного из торцов датчика.the signal doubles in comparison with the signal picked up at one of the ends of the sensor.
