Abstract

One of the consequences of load imbalance is the flow of current in the neutral wire. The current flowing on the neutral wire will cause heat, so indirectly, the consequences of load imbalance contribute to losses for PLN as a producer of electricity. The purpose of this study is to the percentage of transformer load imbalance, the percentage of losses due to neutral current in the transformer neutral conductor. The method used in this research is collecting distribution transformer load data on the Melati extent. From the results of the data analysis, it is obtained that the largest percentage of load imbalance occurs in transformer AB-225 with a loading percentage of 64.95% LWBP and 65.74% WBP. Based on the results of the analysis the total percentage of losses due to the neutral current on the neutral conductor of the transformer is 7.89% and 9.76% LWBP and WBP, respectively.

Abstract

Salah satu sistem proteksi yang terpasang pada menara transmisi adalah system pembumian yang berada pada kaki menara transmisi. Nilai resistansi pembumian menara transmisi dipengaruhi oleh beberapa faktor, antara lain dipengaruhi oleh jenis tanah. Berdasarkan PUIL, IEC dan SNI bahwa standar nilai pembumian untuk jaringan transmisi 150 kV adalah kurang dari atau sama dengan 10 Ω. Saluran tower transmisi 150 kV jalur Bolangi-Maros termaksud daerah yang cukup rawan terhadap sambaran petir yang dapat menyebabkan fenomena BFO pada transmisi. Tujuan penelitian ini adalah untuk melakukan pengukuran untuk mengetahui nilai pembumian dan membandingkan hasil pengukuran setelah dilakukan perbaikan pada transmisi Bolangi-Maros. Metode penelitian ini dilakukan dengan analisis data yang dilakukan pada sebelas tower transmisi. Hasil pengukuran tower transmisi line Bolangi-Maros menggunakan Earth Tester Magger, Menunjukan bahwa nilai tahanan pembumian masih memenuhi standar yaitu kurang dari 10 Ω. Untuk hasil perhitungan menghasilkan 6,68 Ω dengan jenis tanah liat dan 2,01 Ω dari tanah sawah. Setelah dilakukan perbaikan dengan metode direct grounding pada tower 70, 95 dan 104 menghasilkan masing-masing 0,78 Ω,0,72 Ω, dan 0,55 Ω. Dari hasil tersebut menunjukan bahwa nilai pembumian kaki tower tersebut dalam keadaan baik. Oleh karena itu melakukan pemasangan direct grounding pada setiap line transmisi dapat menjadi sistem proteksi.

Abstract

Pemanfaatan teknologi kelistrikan di Bandara Haluoleo salah satunya pada pelayanan pesawat, berguna memandu melakukan take off dan landing. Salah satu peralatan yang terdapat pada pelayanan pesawat yaitu AFL (Airfield Lighting System) yang digunakan membantu pesawat menuju landas pacu maupun ke tempat parkir menggunakan lampu. Penelitian ini bertujuan untuk mengetahui perbandingan intensitas cahaya serta perbandingan efisiensi lampu halogen dan LED pada AFL. Data yang diperoleh dari Bandara akan dianalisis dengan menggunakan rumus dan data yang tersedia. Setelah data teknis yang dibutuhkan telah lengkap, selanjutnya perbandingan lampu LED dengan halogen pada AFL sebagai upaya efisiensi penggunaan energi listrik. Hasil perhitungan kuat cahaya pada lampu halogen di taxiway alpha dan lampu LED di taxiway bravo Bandar Udara Halu Oleo, menunjukkan bahwa kuat cahaya yang dihasilkan pada lampu halogen dengan daya 45 Watt sebesar 2.239,25 Cd. Sedangkan kuat cahaya yang dihasilkan pada lampu LED dengan daya 15 Watt yang menggunakan faktor refleksi 0,98 sebesar 6.539,05 Cd. Hasil perhitungan penggunaan energi pada lampu halogen pada taxiway alpha dan lampu LED pada taxiway bravo Bandar Udara Halu Oleo dalam setahun menunjukkan bahwa penggunaan energi pada lampu halogen sebesar 768,86 Kwh dengan biaya Rp 1.110.786,17. Sedangkan penggunaan energi pada lampu LED sebesar 256,28 Kwh dengan biaya Rp 370.256,06.

Abstract

The current Southeast Sulawesi electricity system has two main power plants, namely the Nii Tanasa PLTU with a capacity of (1´30 MW) and the Moramo PLTU (DSSP) with a capacity of (2´50) MW and has also been interconnected with the South Sulawesi electricity system with the addition of a substation in Bombana, meaning that the power needs of the Kendari electricity system have increased, which can result in increased losses and drop voltage . The purpose of this study is to see the condition of the large value of Current, Voltage, active power flow and reactive power on each bus between channels, and to see the value of the short circuit fault current at the fault location point. after the addition of the Bombana GI, Single line modeling using the help of ETAP 19.0.1 software. based on the results of the research that has been done the value of the power generated by the generator after the entry of the Bombana GI is 271.527 MW where previously it was 211.975 MW, the voltage condition before the entry of the Bombana GI is 96.05% - 99.23% of the previous 97.95% - 99.53%, based on the percentage of Drop Voltage is in the range of 0.022%−0.872% which is still within the SPLN operational standard limit. Then the Total Losses on the channel is 1168.92 KW. The largest Short Circuit current value after the entry of the Bombana GI in the Southeast Sulawesi system for 3-phase short circuit current is 10.267 KA, phase to ground is 10.637 KA, phase to phase is 8.920 KA, and two phases to ground is 10.537 KA.

Abstract

The grounding system is a critical component of an electrical installation because it diverts fault currents to the ground and limits potentially hazardous voltages. This study aimed to evaluate the condition of the existing grounding system in a retail warehouse, analyze the initial effectiveness of a mixture of limonite, wood charcoal, and gypsum as a soil treatment material, and evaluate a recommended grounding design using ETAP. This study employed a quantitative approach through field experiments and simulations. Grounding resistance was measured using an Earth Tester with the three-point method. Five grounding points were treated with a mixture of 2 kg per point, consisting of 40% limonite, 30% wood charcoal, and 30% gypsum. Preliminary results showed an average resistance of 10.46 Ω across the five points. After treatment, the average resistance decreased to 2.23 Ω with an initial effectiveness of 78.68%, and all treated points were below 5 Ω. In the ETAP simulation of the PLN power source, Grounding 1 produced an Rg of 3.295 Ω, GPR of 2,871.8 V, touch voltage of 1,256.1 V, and step voltage of 422.4 V. The touch voltage still exceeded the tolerance limit of 1,141.4 V. Grounding 2 reduced Rg to 1.860 Ω, GPR to 1,621.0 V, touch voltage to 648.3 V, and step voltage to 219.8 V. These results indicate that the grounding treatment effectively reduced the resistance under the test conditions, whereas Grounding 2 improved the safety of the grounding system in the PLN power source simulation scenario. Keywords: grounding system, grounding resistance, soil treatment, ETAP, touch voltage.
