TVA'S PROGRAM TO UTILIZE FIBER OPTICS AND OPTICAL SENSORS FOR POWER SYSTEM APPLICATIONS

.
(-)

Abstract

Following numerous violent and destructive explosions of oil-filled freestanding current transformers CCTs>, TVA's Division of Energy Demonstrations and Technology initiated a program to evaluate the use of fiber optics and optical sensors as potential alternatives to existing CTs. In addition, these devices offer the promise of being able to function effectively in such harsh environments as very high electromagnetic fields resulting from extra high voltages CEHV>, dense radioactive bombardment from such sources as nuclear reactors, and elevated temperatures and pressures commonly found in steam generators. While several optical sensor systems have been investigated and demonstrated in the laboratory environment, the first real field test will occur in the spring of 1986 with the installation of a magneto optical current transducer <MOCT>.
