Studi Analisis Koordinasi Over Current Relay (OCR) dan Ground Fault Relay (GFR) pada Recloser di Saluran Penyulang Penebel
ABSTRACT: Short circuit
causing over current problem and can might causing interference of the
equipment performance such as distribution transformers also causing widespread
disruption occurred. In resolving such interference is required as protection
system on the distribution system. Seeing all above is needed coordination
between the supporting component of the protection system which is consisted of
Over Current Relay (OCR) and Ground Fault Relay (GFR). The research was
conducted at PT. PLN (Persero) South Bali Area Network, INDONESIA on recloser
in the feeder line of Penebel. OCR setting between the Relay feeder of Penebel,
Recloser Celagi, Recloser Bakisan, and Recloser Benana still less selective,
with time value coordination between average security was still less than 0,2
second. Then OCR setting and GFR relay feeder of Penebel, Recloser Celagi,
Recloser Bakisan, and Recloser Benana was recommended for re-setting in order
to minimize disruption and electric power distribution system to be reliable.
