Analogue DCVG Set Constituents

Analogue DCVG Set

In surveying a pipeline, the operator walks the pipeline route testing for a pulsing voltage gradient at regular intervals. As a fault is approached, the surveyor will observe the analogue meter needle begin to respond to the pulse, pointing in the direction of current flow that is towards the fault. 

When the fault is passed the needle direction completely reverses and slowly decreases as the surveyor moves away from the fault.
By retracing to the fault, a position of the electrodes can be found where the needle shows no deflection in either direction (a null). 

The fault is then sited midway between the two electrodes.
