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 transmission line surge arrester (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 AEP´s 800 kV orange station. 800 kV is the maximum design operating voltage and 765 kV is the nominal operating voltage. Successful field test results of the TLA´s ability to limit switching overvoltage 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.
