This idea is more like a weapon for revolutionaries. Large computer installations and communication equipment are housed in large buildings in downtown areas. The electricity that powers them run under the streets and are encased in heavy conduit. It is also very high voltage. It gets stepped down by a transformer after it enters the building. The top picture is a probe for electronics that will pierce the wire so a measurement can be made of whatever voltage exists on the wire without cutting the wire. The idea is to do this to 2 circuits outside the building and short one circuit to another and send a surge into the building. You would have to break open the conduit somehow to expose the wire. Or maybe pierce the conduit with the wire. It can be activated remotely after it is in place.
