Представлено применение методов контроля изоляции сетей низкого напряжения постоянного и двойного рода тока с помощью вольтметра и резистора. Приведены формулы для вычисления сопротивления изоляции методами двух и трех отсчетов вольтметра. Предложен новый способ двух отсчетов вольтметра для сетей двойного рода тока. Представлена модификация рассматриваемых методов, ограничивающая их основной недостаток – длительность переходного процесса. Представлено застосування методів контролю ізоляції мереж низької напруги постійного і подвійного роду струму за допомогою вольтметра і резистора. Наведено формули для обчислення опору ізоляції методами двох і трьох відліків вольтметра. Запропоновано новий спосіб двох відліків вольтметра для мереж подвійного роду струму. Представлена модифікація розглянутих методів, що обмежує їх основний недолік – тривалість перехідного процесу.
