Abstract

Pemilihan bahan isolasi yang fleksibel atau lentur bertujuan untuk memastikan bahwa isolasi tersebut efektif dalam menahan panas atau dingin, tahan terhadap kerusakan, dan bisa diaplikasikan. Dengan mempertimbangkan faktor-faktor tersebut, maka bahan isolasi dalam penggunaannya dapat memberikan perlindungan maksimal terhadap perpindahan panas dan meningkatkan efisiensi energi. Hal ini dapat membantu mengurangi biaya energi dan memperpanjang umur pemakaian isolasi. Hasil dari pengujian kertas isolasi dengan ketebalan 1,04 mm pada keadaan kering menunjukkan nilai rata-rata breakdown voltage sebesar 6,7 kV dan dengan ketebalan yang sama 1,04 mm pada keadaan direndam minyak menunjukkan nilai rata-rata breakdown voltage sebesar 23,82 kV, hal tersebut menandakan bahwa kertas isolasi dengan metode perendaman memiliki breakdown voltage lebih baik dibandingkan kertas isolasi dalam keadaan kering. Pengaruh ketebalan kertas isolasi terhadap tegangan tembus atau breakdown voltage adalah semakin tebal suatu kertas isolasi maka semakin besar juga tegangan tembus yang dihasilkan, hal tersebut didapatkan menggunakan analisis regresi linier sederhana dimana variabel X berpengaruh terhadap variabel Y dengan nilai korelasi sebesar 0,998.Kata kunci: transformator, kertas isolasi, tegangan tembusTesting the influence of the thickness of press paper type insulating paper on the transformer to the breakdown voltageAbstract: Choosing flexible or bendable insulation materials aimed to ensure that the insulation is effective in retaining heat or cold, resistant to damage, and can be applied. By considering these factors, the insulation material used can provide maximum protection against heat transfer and increase energy efficiency. This can help reduce energy costs and extend the life of the insulation. The results of testing insulation paper with a thickness of 1.04 mm in the dry state shows an average breakdown voltage value of 6.7 kV and with the same thickness of 1.04 mm in an oil-immersed state shows an average breakdown voltage value of 23.82 kV, this indicates that the insulating paper with the immersion method has a better breakdown voltage than insulating paper in a dry state. While the effect of the thickness of the insulation paper on the breakdown voltage is that the thicker the insulation paper, the greater the resulting breakdown voltage, this was obtained using a simple linear regression analysis where the X variable affects the Y variable with a correlation value of 0.998.Keywords: transformer, paper insulation, breakdown voltage

Abstract

Ketidakseimbangan merupakan suatu keadaan yang disebabkan salah satu ataupun seluruh fasa pada tarnsformator mengalami perbedaan, terjadi dikarenakan besarnya beban pada tiap fasa berbeda. Hal tersebut mengakibatkan adanya arus yang mengalir pada penghantar netral yang menimbulkan terjadinya rugi arus netral, serta kerugian berupa daya yang hilang dan dapat menyebabkan kerugian secara ekonomi. Pada saat dilakukan pencatatan beban gardu distribusi XY, besarnya nilai beban pada tiap-tiap fasanya berbeda, sehingga menyebabkan terjadinya rugi arus netral sebesar 2,03 kW dengan besarnya daya yang hilang sebesar 240844,2367 kW. Untuk mengatasi hal tersebut, maka perlu dilakukan pemerataan beban dengan memindahkan beban pada fasa yang tinggi ke fasa yang memiliki beban lebih rendah menggunakan atau diistilahkan pecah beban. Hasil yang diperoleh besarnya rugi arus netral turun menjadi 0,003 kW dengan besarnya daya yang hilang sebesar 45793,79 kW. Sedangkan pangaruhnya terhadap keandalan diketahui bahwa ketidakseimbangan beban memberikan pengaruh terhadap besarnya rugi arus netral berdasarkan perhitungan nilai koefisien korelasi yang didapatkan bernilai 0,24543558 meskipun termasuk dalam kategori rendah. Dari hasil kajian tersebut bahwa ketidakseimbangan beban dengan menggunakan metode pecah beban dapat menurunkan nilai arus netral dan besarnya daya yang hilang, yang berimplikasi rugi arus netralnya menjadi lebih rendah. Imbalance is a condition created by variances in one or more of the phases in the transformer, which happens because the magnitude of the load on each phase is different. This causes current to flow in the neutral conductor, resulting in neutral current losses, as well as power losses and economic losses. The magnitude of the load value on each phase varies when the XY distribution substation load is recorded, resulting in a neutral current loss of 2.03 kW and a power loss of 240844.2367 kW. To accomplish this, the load must be equalized by shifting the burden from the high phase to the phase with a lower load, a process known as load breaking. The magnitude of the neutral current loss was reduced to 0.003 kW, resulting in a power loss of 45793.79 kW. While it is known that load imbalance influences the amount of the neutral current loss, based on the calculation of the correlation coefficient value obtained is 0.24543558, despite being in the low category. From the results of the study, the load imbalance using the load rupture method can reduce the value of the neutral current and the amount of power lost, which has implications for lower neutral current losses.

Abstract

Sejak integral diperkenalkan oleh Newton dan Leibniz pada abad ke-17, alat ukur ini terus dilakukan kajian dan perumuman hingga saat ini. Terdapat tiga integral yang dikenal secara luas yaitu integral Riemann, integral Lebesgue dan integral HK. Pada masanya integral Riemann diterapkan untuk menyelesaikan berbagai persoalan tetapi kemudian diketahui memiliki keterbatasan. Integral Lebesgue muncul untuk mengatasi keterbatasan ini. Integral Lebesgue pun kemudian diketahui memiliki keterbatasannya tersendiri sehingga muncul integral Henstock-Kurzweil (integral HK) untuk mengatasi keterbatasan integral Lebesgue. Dalam banyak literatur seringkali untuk menyelesaikan soal integral tidak menggunakan definisi/ kerangka acuan yang sama sehingga sangat sulit memahami substansi maupun keterkaitan ketiga integral ini. Oleh karena itu, pada penelitian ini dilakukan perbandingan penyelesaian persoalan integral menggunakan definisi. Adapun dari empat persoalan integral yang dibahas, integral Riemann dapat menyelesaikan satu persoalan, integral Lebesgue dapat menyelesaikan dua persoalan dan integral HK dapat menyelesaikan seluruh persoalan yang dibahas.

Abstract

The use of electricity has now become a primary need for people who are used for activities as an energy source such as: lights, air conditioners, water pumps, washing machines, TVs, etc. and the longer the need for electrical energy in Indonesia is increasing while power plants are constantly increasing, this forces the government to continue to build power plants to meet the needs of electrical energy in the community. Of course, the construction of this power plant uses very large costs and various obstacles, one of the obstacles is that fuel that used to be a power plant used a lot of oil, now switches to gas and coal to reduce high electricity production costs. The research method that will be carried out is by feeding the generator output back into a rotor drive energy source so that there is a continuous circulation of energy so that the generator output can be charged according to the remaining power capacity fed by the generator. Based on the test results, results were obtained using a 25 Watt DC motor when the input voltage was 12 Volts the power generated on the motor was 13.8 Watts with a motor speed of 768 rpm. Testing on an 800 Watt generator obtained a maximum rpm result of 764 and a vout of 13.8 volts. the highest input voltage (Vin) obtained was 10.06 volts, the output voltage (Vout) was 3.9 volts, and the power produced was 41.34 Watts. The prototype design that was tested produced energy even though the results were still not significant.

Abstract

Solar panels are a technology that utilizes solar energy to be converted into electrical energy. Solar panel technology can be used to generate electricity on a small scale to a large scale. The performance of solar panels depends on environmental factors, namely solar radiation, and temperature. Environmental factors will reduce the electrical efficiency of solar panels due to the increase in operating temperature of solar panels, the greater the temperature will affect their efficiency. Based on tests conducted on photovoltaic (PV) using halogen with different power, the greater the power value in halogen lamp light, the smaller the efficiency, while the greater the temperature of the solar module, the smaller the efficiency. The greater the increase in temperature, the PV efficiency tends to decrease. Based on the results of the study, it shows a significant correlation that, between PV surface temperature and PV efficiency is inversely proportional. While the effect of temperature on efficiency can be said to be quite influential, where in testing with a 300-watt halogen lamp the error rate or R value is 0.6339, while the 500-watt halogen R value is 0.8493 which means it is more accurate and the effect is quite strong.

Abstract

Distributed generation (DG) is an approach that involves adding decentralized power generation within a distribution network. Distributed generation systems can reduce transmission losses, increase the reliability of energy supply, minimize carbon emissions, and enable the active participation of consumers in energy production. However, with the increase in distributed generation, electric power systems face new challenges in maintaining operational reliability and safety. Disruptions such as short circuits or overcurrent can occur in the system, and appropriate protective responses are required to protect the power grid from more significant damage. The addition of DG also causes the short circuit current to vary and results in system protection coordination having to be redone. Carrying out coordination will take a long time. This research uses modeling and simulation of a distributed generation system with various operating conditions and works adaptively according to changes in the system due to the addition of DG. The results obtained from the simulation are used in neural network training to study the relationship patterns between directional overcurrent relays (DOCR) parameters and system operating conditions. The backpropagation algorithm is used in the Artificial Neural Network (ANN) training process. The training process utilizes the maximum Short Circuit Current (ISC) input obtained through generation, fault location, and fault type. Time Dial Setting (TDS) and Ipickup values are used as ANN training targets. After testing, the results obtained are in accordance with the target data. The efficacy of this method is further demonstrated through ETAP simulations, which confirm that ANN is a suitable approach for modeling adaptive and optimal relay coordination systems.
