Inspecting and protecting buried piping in presence of electrical grounding This is the principle and method used for ACVG surveys; two soil-contact probes (metal or half cells can be used) are placed on the ground making soil contact and measuring for pressure spikes (increased voltage) along ...
ACVG is similar to DCVG with the exception that the applied current is an alternating signal. Inspecting and protecting buried piping in presence of electrical grounding By using of locating method of insulation defects, is preventing the occurring of accidental corrosion and in this case prevention ...
