FIELD: measuring equipment.
SUBSTANCE: invention relates to instrumentation and can be used to quantify corrosive state grounding devices elements of substations electrical installations of various type and purpose without overburden. Method of corrosion condition detection of grounding devices, including measuring total elements weight of grounding devices, ground humidity at location place of grounding device, resistance to current flow, presence and magnitude of wandering currents. In this case, ground loss of grounding electrodes and change in current flow resistance are additionally measured. Passing from physical values of variables to coded ones. Corrosion of grounding devices is calculated by ground loss of grounding electrodes or changes in current flow resistance of earthing switch.
EFFECT: technical result is increase in accuracy of corrosion state detection of grounding devices elements without soil opening.
