摘要
Abstract
DC optical current transformer(OCT)is an important equipment in high voltage direct current(HVDC)transmission project.Its safety and stability is of great significance to the power grid.In this paper,the causes of a DC optical current transformer fault at a converter station are analyzed and the possible location of the fault is investigated.Finally,it is determined that the change in the characteristic parameters of the fault is caused by the cracks produced after the long term deterioration of the optical fiber melting point.This work is of certain reference value for fault analysis of the OCT in engineering.关键词
