Abstract :
An 800-kV metal oxide transmission line surge
arrester (TLA) has been developed, installed and tested on the
AEP 765-kV Marysville–Kammer transmission line. The purpose
of this TLA is to pave the way for the development, construction
and application of an 800-kV SF6 dead tank circuit breaker
without closing resistors and free standing current transformers
at American Electric Power’s (AEP) 800-kV Orange station. Eight
hundred kilovolts is the maximum design operating voltage, and
765 kV is the nominal operating voltage. Successful field test results
of the TLAs ability to limit switching overvoltages emanating
from circuit breaker operation to below the transmission line
switching withstand are given. In addition, successful test results
of the 800-kV dead tank circuit breaker design dielectric test are
given in this paper.
