Analisis Hubungan Singkat Satu Phasa Ke Tanah Terhadap Pengaturan Setting GFR Pada Feeder 20 Kv ( Application GI Pauh Limo )

Asnal Effendi


Disturbance that often happen with network that put in distribution 20 kV. This disturbance caused by lightning, animal and tree that hit by electrical power disturbed or having extinct. As protection from that disturbance, attached protection system from distribution system or tranmission system and generator, such as ground fault relay to protect phase disturbance to the ground. Calculation of short circuit current fault for relay coordination protection need not only for one spot fault, but only current contribution from source that flow to the disturbance spot. Case study of this research is applicated to value setting in GI Pauh Limo that is 0,3 while in analysis calculation for value setting in BLKI feeder and KANDIS found that the value is 0,32 and 0,3 with disturbance spot location in 100% from each network feeder. This simulation calculation process used EMTP.
