INSTALLATION To investigate the influence of environmental factors and stray currents on corrosion of grounding devices

摘要

The invention relates to the experimental facilities for research in the field of electrical safety, in particular, to study the effect of environmental factors on the corrosion state of the elements of grounding devices.; Apparatus for investigation of the influence of environmental factors and stray currents on the corrosion process of grounding devices comprises laboratory avotransformator LATR connected to an isolating transformer, earthing electrodes connected in series with miliampermetrom and in parallel with the voltmeter, and submerged in the ground, filled in a dielectric bath at the bottom which is a copper foil, while submerged in the ground further device electrodes for measuring moisture and soil acidity.; Using the inventive setting allows to determine the effect of lot factors (moisture, pH, chemical and mineral composition) and stray current corrosion on process elements grounding devices. Determination of the influence of these factors on the corrosion process in the future will determine the effective life of the grounding devices, which will contribute to the normal operation and ensure the safety of electrical personnel.; 1 bp yl 4.
