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>.
