Abstract : In electricity supply industries the environment for communication is extremely hostile. Communication for the safe and efficient operation of the supply system must be error free, particularly during disturbances when intense bursts of electrical radiation and large variations in ground potential are present. The Central Electricity Generating Board, recognising the potential that optical communication could offer, embarked in 1976 on a period of research into optical communication over high voltage lines. As a result, the world's first fully engineered system was installed, in 1982, when the ground wire on a 400 kV transmission line was restrung using a composite conductor. The installation of the 34Mb/s 1300nm optical - pcm link was carried out jointly with BICC and Plessey. Subsequent experience, particularly 400 kV fault throwing tests, has proved its immunity to any form of interference. (Author)
