PROFIL SURJA HUBUNG KARENA PROSES ENERGIZED (PEMBERIAN TENAGA) PADA SALURAN TRANSMISI 500 KV

Abstract

Yuniarto, in this paper explain that transient over voltage that happened because switching surge have to
be paid attention to don't cause the damage equipments of insulation coordination system. This research aim to
perceive the transient over voltage at the end of 500 kv transmission line caused energized process by using EMTP
(Electromagnetic Transients Program) as toll to simulate the energized process. Data for this research was taken
from 500 kv transmission line Ungaran-Pedan. From this research was expected can become a reference for power
company in planning insulation coordination at transmission line.
Result of research show that transient over voltage at the end of 500 kv transmission line caused energized
process reach more or less twice its nominal voltage
Key word : energized, karateristik, transient over voltage, EMTP
