An inverter is an electronic device used to convert DC current into AC current. Inverters have various types according to the type of phase, control wave and generating capacity. Inverters play a very important role as the main supporting component in solar power plants, therefore selecting a good inverter is one of the main points in building this plant. In this plant there are 8 inverters whi…
Polymeric materials such as epoxy resin are widely used as insulating materials in electrical devices, but polymer epoxy resin materials are generally susceptible to environmental influences and exposure to electric fields. To improve the insulating deficiencies of epoxy resin polymers, additional particles can be added. The addition of excess particles can result in a decrease in the quality o…
This study was conducted to obtain dielectric characteristics in form of breakdown voltage and leakage current in Kraft Paper insulation impregnated in sesame oil with a variety of treatment times of 8; 16; and 24 hours. The samples used are square sheets of kraft paper measuring 25 mm x 25 mm and thickness of 0.04 mm. The breakdown voltage test was conducted using a needle-plene electrode syst…
Study of the effect of bubbles on canola oil as insulation in breakdown voltage using a 220 VAC voltage source, with a frequency of 50 Hz. This experiment used two plane electrode system with a diameter of 40 mm and a distance between the two electrodes set at 2.5mm, using a plastic needle as a tool for injecting bubbles. There are three types of bubbles: single bubbles, string bubbles, and clu…
This study reported the formation of electrical treeing that occur on the epoxy resin insulating material with a thickness of 1 mm. The electrode system resembles a leaf-like sample specimen with a gap between the tip of needle electrode and aluminum tape of 1 mm. The samples were given 1% of the pollutant in the form of ammonia (NH3) with a variation of the conditioning time 12; 24; 48; and 96…
Solar Power Generation (SPG) is a rapidly growing renewable energy source in meeting global energy demands. Fresnel lenses are components used in SPG systems to enhance solar radiation absorption by solar panels. In the use of Fresnel lenses, the placement distance can affect the power output of the solar panels. The research findings indicate a significant influence between the placement dista…
Basically electricity has a very important role in everyday life. As we know, electricity is a primary need for industry, offices, shops and households. In its service, the State Electricity Company (PLN) often encounters problems, so it is not uncommon for it to be disconnected, both for maintenance purposes and for interruptions. To anticipate power outages by state electricity companies such…
Indonesia is a developing country with all the developments in every sector and is also supported by technological advances. Without an exact formula that can determine the magnitude of the electrical load at any time, what can be done is to predict the electrical load. The load forecasting method discussed in this thesis is the Backpropagation Artificial Neural Network (ANN) method. After the …
Energy needs are increasing from time to time. People really need electricity for personal use, household activities, education, office activities and companies. Hydroelectric power plant is one of the most widely developed power plants in Indonesia. Micro hydro power plant or abbreviated as PLTMH is one of the right choices to be developed in Indonesia's natural conditions. The construction of…
The use of solar energy as electrical energy with Solar Power Plants (PLTS) is very necessary because the amount of electrical energy demand in Indonesia tends to increase. Solar Power Plants (PLTS) have advantages such as not producing air pollution, and being easy to obtain. In this study PLTS is associated with the performance of electric stoves. The purpose of this study is to simulate the …
The need for electrical energy also increasing over the time, which increases the use of fossil fuels. In order to overcome the issue of increasing the use of fossils, the alternative solution is the new renewable resources which is solar thermal energy. The utilization of solar thermal energy can use thermoelectric module TEC1-12706. While in this research will varies the waterblock cooler app…
Electrical energy very important in daily life for activity. PV Power Plant System is a power plant that utilization solar energy as a source of energy and also can be alternative energy for reduce fossil fuel use. DC LED Lights is one of the light that has excess to be used as lighting especially for room. The utilization of solar cell panel in Pesantren Darul Tauhid Indralaya purpose to deter…
Various studies and studies have been conducted to look for alternative liquid insulation. Vegetable oil is considered the most potential because it has the advantage of non-toxic, waste substances due to reactions in the form of CO2 and water, can be biodegradable, high flash point, has better thermal characteristics and can be renewed ( renewable). In this study, POME was used as a raw materi…
Energy sources from nature are decreasing day by day, based on this, an alternative energy source in the form of Piezoelectric is needed. A prototype was made by varying the circuit to determine the amount of power produced by each circuit. In this study, the Piezoelectric prototype was assembled on a PCB board with the main components, namely Piezoelectric PVDF (Polyvinylidene Flouride) as man…
