Ross Meter® ACVGD® Fault Locator ACVGD


Find underground electrical faults with this simple to use fault locator.  The Ross Meter ACVGD® was designed by Herman B Ross, a 30 year veteran of Dominion Power and electrical engineer. Operators are not required to isolate the source or load because the ACVGD® Ross Meter® makes use of the existing 60 hz A.C. voltage that is still energizing the faulted cable. The Ross Meter® is passive and is never connected to the load or the cable in question. Use of the ACVGD® Ross Meter® effectively results in a 90% reduction in set-up and operation time. The operator merely walks out to where the cable is buried and begins to probe along the path of the cable. The Ross Meter® does not require the operator to place a signal onto the faulted cable.
