"PLN akan mebangun saluran transmisi tegangan tinggi arus searah (HVDC), saluran ini meliputi transmisi udara di Pulau Sumatera, saluran kabel bawah laut di Selat Sunda, dan transmisi udara di Pulau Jawa. Salah satu cara untuk mendapatkan saluran yang efektif adalah penggunaan kawat berkas. Dalam penentuan kawat berkas yang efektif, pada penelitian ini akan digunakan pertimbangan - pertimbangan karakteristik HVDC, seperti pertimbangan susut tegangan, kerugian daya karena korona, gangguan bising, daya hantar arus ,dan massa konduktor. Dari hasil penelitan diperoleh saluran transmisi HVDC yang efektif, yaitu saluran ganda dengan kawat berkas 5 konduktor ACSR untuk diameter keselurahan masing - masing konduktor 29,9mm - 38,21mm dan saluran ganda dengan kawat berkas 4 konduktor ACSR untuk diameter keseluruhan masing - masing konduktor 38,22mm - 48,85mm.

One way to get an effective channel is the use of the bundle conductor. The use of bundle conductor is expected to minimize power losses, the corona, and increased ampacity. In determining the effective bundle conductor, in this study will be used considerations of the characteristics HVDC, such as consideration of voltage drop, corona power loss, audible noise, ampacity, and the mass of the conductor. The research results for the effective HVDC transmission line are double circuit channel with 5 bundle conductor , each ACSR conductor has overall diameter about 29,9mm - 38,21mm and double circuit channel with 4 bundle conductor , each ACSR conductor has overall diameter about 38,22mm - 48,85mm."

"Dalam rangka meningkatkan pendapatan, PT.PLN (Persero) melaksanakan perjanjian jual beli tenaga listrik dengan PT. Lotte Chemical Indonesia Cilegon. berupa investasi relokasi saluran udara tegangan tinggi 150 kV. Penelitian ini begitu penting sebagai simulasi skala kecil mengingat banyaknya proyek transmisi tenaga listrik yang dilaksanakan PLN. Penelitian ini menganalisis dampak relokasi SUTT 150 kV tersebut ditemukan bahwa material eksisting yang dibongkar baik yang termanfaatkan/ tidak termanfaatkan kembali sehingga berpotensi menjadi penambah/pengurang investasi bagi PLN. Metode penelitian berupa analisis data kajian kelayakan proyek PLN. Analisis perhitungan dengan menghitung nilai asset eksiting yang kemudian digunakan sebagai acuan dalam perhitungan analisis sensitivitas yang kemudian ditentukan 3 skenario dengan menggunakan indikator finansial IRR, NPV, B/C Ratio dan Payback Period (PB). Hasil penelitian menunjukkan bahwa untuk Skenario 1,2 dan 3 mempunyai nilai IRR dan B/C Ratio positif dan terdapat selisih 1 tahun untuk payback period antara skenario 1 dan 3 vs skenario 2 dan untuk NPV tertinggi ada di skenario 3.

In order to increase revenue, PT PLN (Persero) entered into a power purchase agreement with PT. Lotte Chemical Indonesia Cilegon. investment in the relocation of 150 kV high voltage overhead lines. This research is very important as a small-scale simulation given the large number of electric power transmission projects implemented by PLN. This study analyzes the impact of the relocation of the 150 kV SUTT and found that the existing material that was dismantled was either utilized/not reused so that it has the potential to increase/decrease investment for PLN. The research method is in the form of data analysis on the feasibility study of the PLN project. Calculation analysis by calculating the value of existing assets which is then used as a reference in calculating sensitivity analysis which is then determined 3 skenarios using financial indicators IRR, NPV, B/C Ratio and Payback Period (PB). The results of the study show that skenarios 1, 2 and 3 have positive IRR and B/C ratio values and there is a difference of 1 year for the payback period between skenarios 1 and 3 vs skenario 2 and the highest NPV is in skenario 3."

"A properly co-ordinated protection system is vital to ensure that an electricity distribution network can operate within preset requirements for safety for individual items of equipment, staff and public, and the network overall. Suitable and reliable equipment should be installed on all circuits and electrical equipment and to do this, protective relays are used to initiate the isolation of faulted sections of a network in order to maintain supplies elsewhere on the system. This then leads to an improved electricity service with better continuity and quality of supply.Written by two practising electrical engineers, this second edition of the best selling Protection of Electricity Distribution Networks (IEE, 1998) offers both practical and theoretical coverage of the technologies, from the classical electromechanical relays to the new numerical types which protect equipment on networks and in electrical plant."
