Abstract

A 1-phase 4-pole starting capacitor induction motor which is used as an activator of the table drilling machine has a more complicated construction because it has a  centrifugal switch which is connected in series with the capacitor for its initial start and a high rotational speed of the stator field, which is 1500 rpm. While a 3-phase 6-pole induction motor has a much simpler construction because it does not require a centrifugal switch and a capacitor for its initial start with a low rotational speed of the stator field, which is 1000 rpm. This study discusses the effect of modifying the stator winding in a 1-phase 4-pole starting capacitor induction motor on the table drilling machine into a stator winding of 3-phase 6-pole induction motor on the rotation of the rotor. Modifications are carried out on the stator winding of a 1-phase induction motor by changing the number of phases, number of poles, type of winding, wire diameter and number of windings per groove. Modifications are carried out on the windings to obtain a 3-phase 6-pole 24-groove induction motor with 200 windings per groove, a wire diameter of 0.5 mm, and a winding type of spiral double layer. In our trials without a load on the induction motor the rotor rotation decreased by 33.71% from 1498 rpm to 993 rpm, and with a load decreased by 36% from 1450 rpm to 927 rpm.

Abstract

Dalam penulisan jurnal ini dibahas tentang Uninterruptible Power Supplies (UPS) atau catu daya yang tidak terputus. UPS atau catu daya yang tak putus merupakan suatu alat yang dapat menggantikan catu daya PLN untuk sementara waktu. UPS mampu mencatu daya bagi suatu beban karena di dalam UPS terdapat akumulator yang dapat menyimpan energy listrik, Namun akumulator tidak akan mensuplai energi kebeban selama catu daya PLN masih bekerja. Akumulator akan bekerja secara otomatis mensuplai arus kebeban bila catu daya PLN padam setelah melalui inverter yang mana mengubah arus DC menjadi AC. Bila catu daya PLN telah normal kembali maka akumulator akan kembali terisi secara otomatis setelah tegangannya berkurang karena telah dipakai untuk men¬suplai beban. Cepat tidaknya energy akumulator habis atau berkurang tergantung dari bebannya, semakin besar bebannya semakin cepat pula energinya habis atau berkurang

Abstract

Kemajuan pesat dibidang teknologi dan perkembangan sektor industri menyebabkan meningkatnya kebutuhan tenaga listrik. tujuan dari pada penelitian ini adalah. Menganalisa sistem reverse power relai generator, mengetahui macam-macam gangguan generator. metode yang di gunakan dalam penelitian ini yaitu penelitian primer dan sekuder Hasil yang didapatkan pada penelitian ini adalah reverse power relay pada BTG Tonasa mempunyai tap daya 0,01 - 0,02 - 0,03, dengan kapasitas daya relay = 9.92 W. Setting yang dipakai pada BTG Tonasa sebesar 4,84 A dengan faktor penambahan 1,3. Pada relay penguatan hilang yang ada pada BTG Tonasa adalah 4,5 A. Dalam kondisi ini relay akan bekerja apabila 1,26 atau 126 % dari arus rated relay. Skala setting waktu yang dipakai pada relay ini adalah Is, 1,5s, 2s, .... 10s. Untuk mendapatkan setting waktu diperlukan waktu yang secepat mungkin agar relay dapat segera bekerja jika terjadi gangguan. Olehnya itu digunakan setting terendah yaitu 1 s. Kesimpulan dari penelitian ini yaitu persentasi proteksi untuk belitan (percentage of winding protected) adalah 89,6 %

Abstract

Distribution network is part of power network closest to society, distribution network is grouped into two namely: primary and secondary distribution network. The primary distribution voltage used by pln is 20 kv, 12 kv and 6 kv. The primary distribution voltage which tends to be developed by pln is 20 kv. This study aims To determine the main cause of disturbance in power distribution network at Rayon Daya Makassar using FTA (Fault Tree Analisys). The results of this study can be seen from the considerable difference between the electrical energy delivered from the substation with the electrical energy generated from customer consumption. The cause of the interference is: JTM component (I1) of 55 disruptions (12.5%), JTM equipment (I2) of 30 disruptions (6.7%), disturbances Transformer (I3) as many as 8 interruptions (1.8%) , natural disturbance (I4) as much as 1 interference (0,2%), external disturbance (E1) counted 15 disturbance (3%), natural disaster (E2) counted 61 disturbance (13,7%), work of other party / E3) as many as 15 disruptions (0.33%), kites, banners or due to faulty electrical distribution network installation (E4) as many as 258 interruptions (58.2%). After conducting research on the causes of disruption of power distribution network at UPJ Rayon Daya Makassar and analyzed using Fault Tree Analyzes (FTA) it is known that the main cause of disturbance is human disturbance, in the form of playing kites, banners, and excavation of PDAM channel. It can be seen that during May 2016 until January 2017 there were 308 disruptions.

Abstract

The development of science and technology is growing rapidly, as well as the development of knowledge about alternative energy. This study aims to analyze the design of the circuit form so as to produce electric current and to determine the operating flow of a series of seawater energy generating devices as a source of electrical energy reserves. The research was carried out by taking measurement data carried out by the Electrical Engineering laboratory. From the results of the measurement experiment the use of sea water explains that at one liter produces a voltage of 0.86 V, when using two liters produces a voltage of 1.85 V, when using three liters produces a voltage of 2.57 V. From the results of the research It was carried out that the voltage contained in 1 container of seawater was obtained 0.68 V, with the information of the lamp being off, and for 4 containers of sea water obtained a voltage of 3.87 V with a description of the lamp of life. This marine energy is used not only to turn on LED lights, but is used to power electricity in a narrow area or even in large areas. If this sea water energy can be developed in Indonesia, then the Indonesian state can save energy, because most of Indonesia's territory is water / sea. Energy sources derived from fossils at any time will soon be depleted. From the results of research conducted, it can be concluded that this sea water can be used as a source of renewable and environmentally friendly energy reserves.
