Abstract

Kegagalan isolasi adalah masalah yang sering terjadi dalam penyaluran energi listrik. Isolasi diperlukan untuk memisahkan dua atau lebih penghantar listrik yang bertegangan agar tidak terjadi lompatan listrik. Apabila pada bahan dielektrik diberikan medan listrik yang melebihi kemampuannya maka isolasi akan mengalami tegangan tembus dan kerusakan peralan listrik sehingga kontinuitas kerja sistem terganggu.Penelitian ini bertujuan untuk mengetahui karakteristik tegangan tembus pada isolasi cair dan isolasi udara serta mengetahui pengaruh suhu dan diameter elektroda terhadap karakteristik tegangan tembus pada isolasi cair dan isolasi udara. Metode pengujian yang dilakukan untuk mencapai tujuan penelitian yaitu menggunakan tegangan tinggi AC frekuensi 50 Hz dengan elektroda bola-bola dan elektroda bidang-bidang. Berdasarkan hasil penelitian diperoleh hasil tegangan tembus minyak transformator dan isolasi udara sebelum diatur suhunya diperoleh nilai tegangan tembus minyak transformator pada elektroda bola-bola berdiameter 1,8 cm sebesar 33,79 kV, diameter 4,9 cm sebesar 36,58 kV, dan diameter 9,7 cm sebesar 39,07 kV, pada elektroda bidang-bidang berdiameter 1,4 cm sebesar 39,91 kV, diameter 4,8 cm sebesar 34,31 kV, dan diameter 16 cm sebesar 39,91 kV. Sedangkan tegangan tembus isolasi udara pada elektroda bola-bola berdiameter 1,8 cm sebesar 7,95 kV, diameter 4,9 cm sebesar 8,27 kV, dan diameter 9,7 cm sebesar 9,13 kV, pada elektroda bidang-bidang berdiameter 1,4 cm sebesar 7,93 kV, diameter 4,8 cm sebesar 8,25 kV, dan diameter 16 cm sebesar 9,25 kV. Setiap terjadi kenaikan suhu pada minyak transformator dan isolasi udara maka nilai tegangan tembus akan semakin menurun dan setiap bertambahnya ukuran diameter elektroda maka nilai tegangan tembus minyak transformator dan isolasi udara akan semakin meningkat.

Abstract

Penggunaan energi listrik telah menjadi hal yang mutlak, seiring dengan berkembangnya perangkat elektronik. Namun dalam penggunaan energi listrik sering menimbulkan masalah seperti terjadi pemutusan  arus listrik pada seluruh beban oleh pemutus sirkuit akibat beban lebih. Permasalahan tersebut sering terjadi pada penggunaan energi listrik skala rumah tinggal yang memiliki kapasitas daya maksimal 450 watt. Penelitian ini bertujuan untuk merealisasikan hardware dan software prototipe pengatur beban pintar, serta dilakukan pengujian untuk mengetahui keakuratan alat dalam pengukuran dan unjuk kerja alat dalam memproteksi beban. Dalam penelitian ini menggunakan metode eksperimen yang didalamnya terdapat beberapa langkah diantaranya adalah perancangan perangkat keras dan perangkat lunak, serta pengujian alat. Berdasarkan hasil pengujian yang di lakukan, hasil perhitungan persentase eror antara pengukuran alat rancangan dengan alat ukur berstandarisasi untuk beban resistif yaitu total daya beban sebesar 2,10%, tegangan kerja beban sebesar 0,44%, total arus beban sebesar 2,36%, dan total cos phi beban sebesar 0%. Sedangkan untuk beban induktif yaitu total daya beban sebesar 0,38%, tegangan kerja beban sebesar 0%, total arus beban sebesar 0%, dan total cos phi beban sebesar 1,03%. Adapun alat rancangan bekerja sesuai fungsinya dengan memutuskan beban yang bukan prioritas jika terjadi beban lebih dalam pemakaian energi listrik.The use of electrical energy has become an absolute necessity, along with the development of electronic devices. However, the use of electrical energy often causes problems such as a disconnection of electric current in the entire load by a circuit breaker due to overload. These problems often occur in the use of residential-scale electrical energy, which has a maximum power capacity of 450 watts. This study aimed to realize the prototype hardware and software for smart load control, as well as testing to determine the accuracy of the tool in measuring and the performance of the tool in protecting the load. It applied an experimental method in which there were several steps, including the design of hardware and software, as well as tool testing. Based on the results of the tests carried out, the results of the calculation of the percentage error between the measurement of the design tool and standardized measuring instruments for resistive loads, i.e., the total load power of 2.10%, working voltage load of 0.44%, total load current of 2.36%, and the total cos phi load of 0%. As for the inductive load, the total load power was 0.38%, the load working voltage was 0%, the total load current was 0%, and the total cos phi load was 1.03%. The design tool worked according to its function by deciding which load was not a priority if there was an overload in the use of electrical energy.

Abstract

Drop voltage and power loss at the distribution system of electricity power in the Kotamobagu Area are caused by several factors, a namely far distance of a place that is distributed by electricity power from the source, imbalance load, equipment age, the diameter of the conductor, a distance of powerhouse to the consumer is too far and connection point are caused for technical loss. If it keeps happening, it will decrease the reliability of the electric power system and the distributed quality of the electricity power as well as it can damage the equipment. Therefore, unbalanced loading should be decreased at the phase, and overloading at the network will cause PT PLN (Persero) loss in the Kotamobagu Area. This research aims to analyze voltage drop, percentage of voltage drop, and power loss at every medium voltage feeder of 20 KV that is supplied from PLTD (Steam Power Plant) Kotamobagu until every transformer of distribution at peak load. After it is analyzed, the feeder OK 1, OK 2, OK 3, OK 4, OK 5 obtain the most significant value of drop voltage for 7.221 KV, 1.94 KV, 6.472 KV, 5.04 KV, 4.878 KV, respectively, with a percentage value of 56.507%, 10.742%, 47.841%, 33.689 %,32.257%.
