PCT No. PCT/EP92/02629 Sec. 371 Date May 13, 1994 Sec. 102(e) Date May 13, 1994 PCT Filed Nov. 16, 1992 PCT Pub. No. WO93/11279 PCT Pub. Date Jun. 10, 1993.An electric power distribution system permitting active cathodic protection of reenforced concrete structures includes a converter device converting a mains supply voltage to low voltage electrical power, a computer in close proximity to the converter device, a cabling system leading electric power from the converter to parts of the reinforced concrete structures requiring active cathodic protection, a device for providing electrical contact between the cabling system and reinforcing iron of the reinforced concrete structures, contact elements providing electrical contact with the concrete mass, and distributing devices for distributing electric power to respective contact elements. While there is only one cabling system, the system permits control of power applied to each respective distributing device and two way communication of digitally coded and addressed information between the computer and digital control portions associated with each of the distributing devices via the cabling system. |
