Abstract
Сеть датчиков со встроенной логикой для контроля состояния работоспособности электроэнергетической системы содержит множество расположенных с интервалом датчиков, которые связаны магнитным образом с линией электропередачи, подлежащей контролю. Датчики содержат блок подачи сигнала и блок считывания сигнала. При этом один из датчиков служит для подачи высокочастотного сигнала в линию электропередачи посредством магнитной связи при помощи своего блока подачи сигнала, в то время как датчики по обе стороны датчика подачи сигнала служат для блокировки поданного сигнала, который затем обнаруживают блоком считывания сигнала датчика подачи и используют для измерения импеданса анализируемого участка линии электропередачи. На основании разности между предварительно измеренным импедансом контролируемой линии электропередачи и фактическим значением импеданса линии электропередачи, измеряемым датчиком, можно определить состояние работоспособности линии электропередачи.
