Instead of relying on exploratory excavations, it samples and analyses the gases emitted when cable insulation starts to break down, via a series of 8mm bore holes. Faults can normally be located in under an hour and to an accuracy better than 1 metre, eliminating the need for multiple exploratory excavations. Normally, the highest concentration of gas is directly above the fault. Business Benefits -Average 50% cost savings on fault location and re-instatement -Even greater savings where there are time-based penalties for disrupting highways -Under one-hour typical time to locate each fault – a fraction of the time taken with conventional methods.
