Abstract

The results of the voltage drop calculation from the MDP panel to the SDP under maximum load conditions (100% loading) show that the largest voltage drop occurs on the Hyundai Lift Power Panel by 0.51%, due to the distance of the conductor to the PP Lift Hyundai being the farthest and the cross-sectional area and the magnitude of the load current being larger than other panels. From the analysis of the comparison of manual voltage drop calculation results against Ecodial simulation, there is an error of 9.8%, while against ETAP simulation there is an error of 5.88%. Based on the results of voltage drop calculations and analysis with manual calculations and Ecodial and Etap simulations in civil buildings, the percentage of voltage drop results is in accordance with PUIL 2011 Chapter 2.2.3 and IEC 60364-5-52 Table G.52.1 standards so there is no need to make voltage drop repairs because electrical conditions on each floor of civil buildings are still in normal condition.

Abstract

The Javan Langur Center is a Javan langur rehabilitation center located in the middle of the Coban Talun forest. In the area there is a river that can be used as a Pico Hydro Power Plant with a crossflow turbine as its main component. The selection of a crossflow turbine aims to analyze the latest design of a crossflow turbine, to determine the effect of the number of blades on the turbine rotation speed in the PLTPH system and to regulate discharge to obtain maximum output. The research began with making 2D designs and then continued in 3D and applied in real form. Data collection is carried out by creating a workflow for the entire process with an analysis method using a comparison of test data and field measurements. After data collection and analysis, the turbine at 100% intake opening produced a turbine speed of 52 rpm without pulleys and produced an output of 18 volts with a current of 0.31 A when connected to a battery.

Abstract

The transmission system is a system that often experiences lightning strikes and can cause back flashover (BFO) if there is a direct strike on the ground wire or on the tower. Lightning strikes can also cause touch voltage and step voltage hazards when lightning strikes the ground surface. Grounding is a safety device that functions to protect equipment, systems, humans and other living beings from electrical surges, especially lightning strikes. The grounding resistance value on the tower must be made as small as possible so as not to cause high tower voltage which can ultimately disrupt the transmission system. The grounding resistance limit according to PUIL 2000 is no more than or equal to 5 Ohms. This study aims to evaluate how feasible the tower and its protective devices are on the tower, including grounding and arresters in the event of a lightning strike. By collecting data, calculating tower voltage and simulating lightning overvoltage with the ATPdraw application. From testing the tower voltage by taking a sample on a tower with the highest grounding resistance of 5.8 Ohms on tower T63, the tower voltage value was obtained at 169.94 when given a current of 20 kA, 345.6 kV when given a current of 40 kA, and 682.03 kV when given a current of 80 kA. By calculation and simulation that the tower voltage value does not cause Back flashover (BFO) so it can be categorized as safe and feasible from lightning strike interference.

Abstract

Motor induksi merupakan motor listrik yang luas penggunaannya khususnya pada industri. Seringkali industri yang terletak jauh di pedalaman, bila terjadi kerusakan pada motor induksi dilakukan perbaikan dengan cara replacement antara motor induksi yang satu dengan motor induksi yang lain dan hanya diperhatikan daya motor dan sistem tegangan yang digunakan, sehinga seringkali dimensinya juga tidak persis sama. Dengan adanya kegiatan replacement tersebut diduga motor induksi tersebut akan mengalami banyak perubahan khususnya lebar celah udaranya. Untuk menghindari nilai effisiensi yang rendah, faktor daya yang buruk, dan kerapatan torsi yang rendah maka jarak celah udara suatu motor induksi tidak dirancang terlalu lebar. Di sisi lain distorsi distribusi kerapatan fluks celah udara dapat diminimalkan dengan memperbesar jarak celah udara. Penelitian ini dilakukan pengikisan sedikit diameter rotor pada motor induksi satu fasa rotor sangkar 1 kW 1000 rpm sehingga lebar celah udara 3,5 mm (Rotor A), 2,5 mm (Rotor B), dan 4 mm (Rotor C). Melalui analisis Finite Element menggunakan software FEMM 4.2 didapatkan kerapatan fluks celah udara tertinggi pada Rotor A 0,456 T, Rotor B 0,634 T, Rotor C sebesar 0,399 T. Sedangkan daya output saat beban nominal masing-masing motor didapatkan 0,77 kW (Rotor A), 1,03 kW (Rotor B), dan 0,69 kW Rotor C).

Abstract

A transformer is a static electric device that is used to change the alternating voltage to a higher or lower level and is used to transfer energy from one electric circuit to another without changing the frequency. When the transformer is working, there is a temperature rise in the transformer which affects the degradation of the insulating paper and transformer oil. This accelerated aging tester applies the drying and vacuuming process as well as the arrangement of paper insulation racks to achieve maximum test results. The research method refers to IEC 60216-3 2006 for aging time, IEC TS 62332-1 2014 and IEC TS 62332-1 2011 as a reference for the Development of Accelerated Aging Experimental Test Cells for Transformer Oil-immersed Paper Insulation Systems. After achieving the existing goals, the addition of the drying process resulted in quite good Breakdown Voltage test results, not only that after the addition of vacuum it produced a good oil color according to ASTM D1500 as well as after the presence of paper placement racks the results of good tensile strength testing were proven by a graph which relatively decreased from sample 1 to sample 3.

Abstract

A transformer is a static device that can transfer electrical energy using the principle of electromagnetic induction. In operating conditions, the increase of temperature in the transformer will cause the oil insulation having disturbance, which will cause the quality of the insulation to decrease. In this research, oil isolation type shell diala b was chosen which was placed in an accelerated thermal aging chamber experiment device. Then shell diala b oil insulation is heated to a temperature of 120 °C and 160 °C with three sampling times. After this, the oil insulation characteristics were tested which includes oil color scale testing and UV-Visible spectrophotometric testing of the oil. The research method used refers to the IEC 60216-3 2006 standard for aging time and ASTM D-1500 COLOR SCALE for color scale testing. After testing the characteristics of shell diala b oil insulation, it was found that the value of the color scale had increased. Besides that, there has been an increase in the absorption of UV-Visible rays within the oil insulation, which causes the color of the insulation become darker as the temperature and the aging duration in the accelerated thermal aging chamber increases.
