The technology makes a audible warning such as a beeping sound as well as a flashing light to warn people and pets not to step on or touch dangerously charged manhole covers and street lamps. Periodic testing of the infrastructure is not good enough, since one second, something can be ok and just a few moments latter, can become electrified. The company that invented the Electrified Cover Safeguard, seems to have patented the concept of an on-site real time stray voltage system. More information on this technology can be found at www.ManholeSafety.com.

The older cables probably have concentric neutrals that are exposed. This means the cables don't have an outer jacket covering them. Over time the exposed neutrals fail and stray voltages start to appear on all kinds of metal objects. Some of these objects might be street light poles, metal enclosures on electrical equipment of the utility company, electric meter bases, t.v. cable boxes, telephone pedestals, and all sorts of other metal objects on the customers property.
