К вопросу измерения с приемлемой погрешностью сопротивления заземления объекта в условиях ограничения разноса электродов схемы измерения

Abstract

The analysis presented shows that it is problematic to provide a requirement for considerable spacing between the electrodes in a three-electrode measuring circuit in compact planning areas. A technique for determination of intrinsic and mutual resistance in the three-electrode measuring circuit under application of the electrode functions interchangeability property is introduced. The novelty of the technique consists in absence of necessity to search a zero potential point for the voltage-operated electrode.
