ANALISIS PENYETELAN PROTEKSI ARUS LEBIH PENYULANG CIMALAKA DI GARDU INDUK 70 kV SUMEDANG
ABSTRAK: 20 kV
distribution of PLN
is not free
from distractions short
circuit. Greatest short circuit fault current occurs at 20 kV bus bar. This led to widespread outages
as a result of the major security operation. The aim of this study was to
identify the final interruption of short circuit current, short circuit fault
current to calculate
and determine the
values Over Current
Relay (OCR) and Ground Fault Relay (GFR). This study
purposed to calculate
short circuit current.
The subject of
research is the disturbances that
occurred in Cimalaka
feeders. The data
required for this
study were obtained from the Area
Manager Distribution of Bandung. The data is analyzed to determine the magnitude
of short circuit
current and Over
Current Relay (OCR)
and Ground Fault Relay (GFR) adjustment.
The results show the short circuit
fault current at 0% distance from feeder
is 2428,391 A and
short circuit current
for 3 phase
is 2103,049 A
short circuit fault
current and the second phase of 570,406 A short circuit
fault current one phase to the ground. The difference in the
relay settings data
from the field
with the calculation
results showed that
the differences are not
too significant, so
the ability of
the relays is
still good. Thus,
the feeder protection relays
Cimalaka at 70 kV substation
Sumedang still good
and doesn’t need to be reset.
