System and method for collecting, analyzing and archiving conduit defect data

摘要

The system utilizes electroscan equipment including a voltage source (40) and current meter with a cable having one end grounded and one end having an electric probe (60) thereon sized to fit within an underground pipe. The probe (60) is able to complete an electric circuit back to ground when the probe is adjacent a defect through which electric currents can pass, thus producing varying electric current. A cable reel can be provided with portions of the cable supported thereon and with a cable distance sensor coupled to the reel along with the current meter and voltage source (40) in the form of a battery. The current meter and distance sensor can transmit wireless signals to an on-site processor, such as a smartphone, for on-site data evaluation. Such unconditioned data can also be transmitted to a remote location for conditioning of the data and retransmission of the conditioned data back to the on-site processor.
