摘要： Extensions exited from electrodes of an electroscan probe, allowing for operation in a wide range of pipe sizes, particularly large diameter pipes, by extending the maximum effective distance of the electric fields generated by the probe. The extensions preferably extend radially from each of the electrodes, and are sized to bring tips of the extensions close to the pipe wall. The extensions can be joined by lanyards to assist in keeping them spaced apart. At least some extensions preferably have bulbous tips, preferably at least partially formed of non-conductive material to keep adjacent extensions from touching each other, especially extensions coupled to different electrodes. The extensions, in one embodiment, are threaded into collars adjacent to each electrode and selected to have a length appropriate for the pipe diameter.
