ABSTRACT:
An apparatus for reducing end effect in anodes used in cathodic protection systems for underground metallic structures and in which the anodes are surrounded by and are in intimate engagement with a carbonaceous material so that an impressed current which is supplied to the anode is discharged from the anode in a substantially uniform current discharge density which is maintained at a level that is electronically conducted by the carbonaceous backfill to the earth. The anode includes an elongated body of electrically conducting material having a plurality of non-conducting segments which separate the body into conducting areas of non-uniform size and which take advantage of mutual interference between adjacent conducting areas to substantially prevent electrolytic current discharge from the anode.
