APPLICATION OF LINE SURGE ARRESTERS ON THE COMPACT TRANSMISSION LINES 110kV IN VIET NAM

Abstract

This paper presents result application of line surge arresters on the compact
transmission lines 110kV in Viet Nam. The results study are based on the
geometric model (EGM) method and EMTP simulation software. The number of
lightning strikes to the compact transmission lines and standard line is calculated
and compared. Different line surge arrester installation configurations are
considered. Line lightning performance is computed for different tower footing
resistance. Line performance before and after line surge arrester installation are
compared. Line lightning performance of the single and double circuits compact
transmission lines combined with line surge arresters are compared with the
performance of the standard line without line surge arresters.
