Abstract

Electrical loads have resistive, inductive and capacitive characteristics. This characteristic will have an impact on the electrical system, namely the power factor. The power factor value is limited from 0 to 1. If the power factor value is close to 1 (high active power), the electrical system will be better, and vice versa, if the power factor is low, it is close to 0 (high reactive power), so that less electrical power can be utilized from the amount of power looks the same. When the electrical system has a low power factor (large reactive power) it will affect the decrease in power quality and increase the use of electric power. In problem identification, it is found that there is a lot of use of electro motors or 3 phase electric motors which produce inductive loads and affect the power factor or cos phi. PLN has determined the minimum value of the power factor is 0.8. If the power factor is below 0.8 then consumers or factories that use it will be fined by PLN. The need for a capacitor bank that is used at a power capacity of 105 kVA with a cos phi of 0.9 is 22.33 kVAR.

Abstract

The higher the growth rate, the greater the need for electrical energy required. In addition, the increase in population has resulted in many land functions becoming non-agricultural or agricultural from non-agricultural land. Therefore, the way to overcome the shortage of food security and environmentally friendly is the aquaponics system. Aquaponics cannot be separated from air circulation, where this water is the main need for both fish and plants. The water pump is an air propulsion driven by electrical energy. The problem is, because the air used for both plants and fish is the main ingredient, the water must flow and if the electricity goes out or other disturbances in electricity, the air flow process will stop, in addition to reducing electrical energy from PLN, one of the efforts that can be done This is done by utilizing alternative energy, namely using solar light energy into electrical energy or called PLTS. In the design of this PLTS using an off grid system. This off grid system is intended as a substitute for electricity when the electricity source from PLN is off or there is no PLN electricity at all. The design of this PLTS is done by calculating the required PLTS components, after that determining where to put the solar panels that are used. After knowing the specifications of the components, then you can do calculations for the Budget Plan (RAB) which will be recommended in the design of PLTS with this off grid system.

Abstract

The increasing demand for electrical energy, the performance of the equipment in the power plant also increases. Transformer is a tool that feels the impact, namely the increasing temperature of the conductor inside the transformer. To find out the indications of failure in the transformer, we can test one type of insulation on the transformer, namely transformer oil, by testing the Dissolved Gass Analysis and testing the breakdown voltage (Breakdown Voltage). After testing the DGA, the TDCG results are analyzed, whether they are in accordance with the IEEE 1991 Standard. And the Breakdown Voltage is in accordance with the IEC 60156 Standard (SPLN). Test results in November 2021, the TDCG value is in condition 2 referring to the IEEE 1991 standard, where in conditions This requires vigilance and must determine the allowable loading. And after testing the breakdown voltage of the transformer oil, it is known that the breakdown voltage condition is ≤ 30 kV, if it is adjusted to IEC 60156 standards, the breakdown voltage value of the oil starts to be LOW/NOT GOOD. When the results of the Dissolved Gas Analysis and Break Down Voltage tests are not in accordance with the Standards, it results in a decrease in insulation resistance which causes not optimal power to be supplied to customers. Therefore, to maintain the performance or life time of the transformer itself, maintenance is needed. Treating oil is an effort that must be made to maintain the insulation resistance according to the permitted standards and the transformer can operate optimally.

Abstract

A Swallow's house is a house that is dedicated as a place for swallows to enter and make nests. The part that can be used by swallows is the swallow's nest. The swallow house itself operates 24 hours. ATS (Automatic Transfer Switch) itself is a system equipment that can regulate the change in the supply of electric power from the main power source from PLN to a backup power source that works automatically by controlling the timing. Therefore, we need a circuit or automatic device that can move the power source from the main source to a backup source or vice versa. By considering the problem points above, an alternative was created to overcome this problem, so a tool called ATS (Automatic Transfer Switch) was created to solve it. In this research, a single-phase ATS will be designed by reducing the number of contactors to get more economical results and easy maintenance. ATS in this study uses a control circuit based on relay and Time Delay Relay (TDR). When the PLN blackout occurs, there is a time delay of 5 seconds before the battery or battery supplies the circuit. This is done to protect the components from damage if PLN occurs for a brief blackout. The outcomes of the ATS design using components such as contactors, relays, TDRs, and inverters. A circuit is formed that can move the power source automatically. This circuit can be applied to cities or other large industries by replacing a backup power source by using an existing power source in the area. The cost of making ATS is quite affordable, ranging from only 2-3 million, and the materials needed to make this ATS are very easy to obtain both through offline and online media, and the price of the materials is very affordable.

Abstract

Alternating current electric generators are widely known in the world of electricity. All electric generators that until now were known to experts in this field require an increase in activation power because an electrical load is required from the electric generator. In other words, with the increase in the electrical load on the generator, the more power will be needed by the driver, whether it is fossil fuel generation, hydropower, or something else. The generator is an important component in the power plant. Generator is a design of an electric machine that can convert kinetic energy into electrical energy. The magnetic field will rotate in accordance with the direction of rotation when the generator gets a rotation from the outside which then results in electromagnetic induction in the coil. In this process, obtain data by plunging directly into the location of the process of rolling generators or electric motors of mechanical and welding workshops. As well as getting other information about the problems contained in the field such as: determining the coil and the coil rolling process, being able to measure and knowing the strength of the coil current, being able to find out the turning process and drilling the main material of the generator. So the impact of applying magnetic gear at a revolution of 375 rpm, the condition of the rotation of the generator without load.
