“…Metode Merz price calculating current digunakan untuk perhitungan arus sebagai dasar perancangan sistem pengaman busbar menggunakan rele diferensial, dimana arus yang masuk dan keluar ini disebut dengan arus diferensial. Arus diferensial bernilai nol, berarti tidak ada gangguan yang terjadi [12], [13].…”

Busbar merupakan bagian utama dalam suatu gardu induk yang berfungsi sebagai tempat terhubungnya semua bay yang ada pada Gardu Induk Dumai, baik bay line maupun bay trafo. Gardu Induk Dumai didesain dengan konfigurasi 2 busbar (Double Busbar). Dan semua ini tidak terlepas dari gangguan. Adanya gangguan yang terjadi pada busbar dapat menghambat proses penyaluran energi listrik ke pemakai (konsumen). Oleh karena itu, sistem proteksi yang handal sangat dibutuhkan untuk melindungi busbar dari gangguan. Beberapa kendala pada Gardu Induk Dumai, Dimana saat ini belum difasilitasi dengan Busbar Proteksi, yang dimana busbar proteksi pada gardu induk sangat berperan penting dalam kehandalan sistem. Maka pada penelitian ini dilakukan “studi kebutuhan perencanaan pemasangan busbar proteksi pada gardu induk dumai” yang dimana sesuai dengan kondisi di lapangan (Switchyard) belum juga difasilitasi Couple Busbar 150 kV. Dengan dilakukannya penelitian ini, maka perencanaannya dibutuhkan CT busbar dengan ratio 2000/1 Amp, setting busbar 1 Iop pada sisi primer 544 Amp, disisi sekunder 0.272 Amp, sensitifitas pengaman 27,2 %, dengan setting resistor 320 Ohm dan busbar 2 Iop pada sisi primer 580 Amp, disisi sekunder 0,290 Amp, sensitifitas pengaman 29 %, dengan setting resistor 300 Ohm kemudian diperlukan non linier resistor pada terminal rele.

This paper describes the application of artificial neural network (ANN) techniques for protecting small power transformer 2 kVA (Terco type). ANN network trained according to the primary and secondary currents data under NN tool, this network performs as a function of differential protection relay. Symmetrical and unsymmetrical faults are analyzed using Matlab environment. ANN network senses the difference in the internal current of both transformer sides and sending a trip to the circuit breaker (CB) at moment of fault occurrence. All the voltages and the currents waveforms affected with the fault and the response time increased according to this technique. Finally, the trip signal and the quick disconnect time were improved according to ANN technique.

The goal of the retrofit at Zamrud substation is to transform a 28 MVA power transformer’s neutral point grounding system from direct grounding to grounding using a 20 Ohm Neutral Grounding Resistor (NGR). The amount of short-circuit current produced will fluctuate with the installation of NGR. It is necessary to re-setting the Ground Fault Relay (GFR) on Zamrud substation. To estimate the value of the short-circuit current after installing the NGR, the impedance matrix approach is used to calculate it. According to the results, LG’s largest short-circuit current is 397.83 A and its smallest is 313.55 A. Meanwhile LLG has a maximum short-circuit current of 5.334.30 A and a minimum short-circuit current of 943.31 A. Therefore, after NGR installation, the value of the relay setting is as follows: GFR pickup current on the transformer grounding GFR relay is 234.29 A, GFR pickup current on the neutral feeder 1 is 19.96 A, GFR pickup current on the neutral feeder 2 is 30.42 A, and GFR pickup current on the neutral feeder 3 is 38.40 A.
