В статье предложен термоэлектрический метод для контроля величины переходного сопротивления контактного соединения. Описан алгоритм обнаружения контактного соединения в сети электроснабжения с сопротивлением превышающем значения указанное в нормативных документах. Алгоритм рассмотрен на примере схемы, содержащей пять контактных соединений и три электроустановки. Алгоритм основан на вычислении контактного сопротивления по измеренным значениям термоЭДС и протекающего тока только в момент включения электроустановки, что позволяет вычислять сопротивление только того контакта, через которое подключена электроустановка. По номеру включаемой или отключаемой электроустановки определяют номера контактных соединений, составляющих цепь электропитания этой установки.
