Abstract: Изобретение относится к измерительной технике и может быть использовано в системах электрохимической защиты подземных металлических сооружений от коррозии, в частности для измерения поляризованного потенциала. Способ измерения поляризационного потенциала подземного металлического сооружения, характеризующийся циклическим повторением совокупности действий, именуемой циклом измерения, состоящим из фазы поляризации, фазы задержки и фазы измерения, применительно к импульсному характеру выходного сигнала катодной станции, в течение фазы поляризации, совпадающей с временем действия выходного импульса катодной станцией, осуществляют поляризацию датчика потенциала, а в течение фазы задержки и фазы измерения, совпадающими с паузой между выходными импульсами катодной станции, исключают возможность такой поляризации; при этом длительность фазы задержки устанавливают достаточной для исключения омической составляющей потенциала, а разность потенциалов, между электродом сравнения и датчиком потенциала, измеренную в течение фазы измерения, регистрируют в качестве поляризационного потенциала, наряду с этим, на протяжении всех фаз цикла измерения потенциала контролируют изменение сигнала помехи, а измерение поляризационной составляющей потенциала осуществляют, если значение сигнала помехи не превышает порог разрешения измерения потенциала. Техническим результатом при реализации заявленного решения является повышение точности измерения поляризационного потенциала и повышение качества контроля сигнала помехи при импульсном характере выходного сигнала источника катодного тока. 1 ил.
