<![CDATA[The number of Gas Insulated Switchgear (GIS) in operation is increasing in Indonesia. GIS failure requires expensive costs andextensive blackouts. Asset reliability management such as SF6 is needed to ensure GIS performance. Several studies have tested thequality of SF6 gas to assess the feasibility and operation of the GIS. However, a complete GIS feasibility study based on SF6 gas qualityparameters has not found. In this study, a condition assessment of the GISTET Kembangan 500/150 kV was carried out based on applicableinternational standards. There is an interesting phenomenon in the form of dew point anomaly and moisture content in severalcompartments, indicating that the gas is moist. The results of this study indicate the operational feasibility of the GISTET Kembangan500/150 kV , the effect of high humidity on GIS operations, and maintenance recommendations.]]>

<![CDATA[DC-DC Converter is a direct voltage (DC) power supply device that is produced by converting DC input voltage into a lower or higher DC output voltage. In its development, the application of DC-DC Converter allows an electronic device to function with a small energy source, where the output voltage can be varied as needed. DC-DC Converters have been widely developed because they have various advantages, including: simpler form and has high efficiency. In this thesis, an Arduino Mega 2560-based current controller will be implemented. The type of current controller implemented is hysteresis current control with the well-known, tested and proven considerations. Current control works if the inductor current rises from the lower limit of the hysteresis band to the upper limit then the switch will be turned off (inductor current above the upper reference Ip.Ref) and if this current drops from the upper limit to the lower limit the switch will be turned on (current inductor under low frequency Iv.Ref). This current control also has advantages in overcurrent protection such as when there is a short circuit in the load.]]>

<![CDATA[Energy is one of the most important needs for humans to support daily life, especially for developing countries such as Indonesia. One of the energies needed in human life is electrical energy. For this reason, innovation was developed, namely a dry-type Single-Phase Transformer with a core geometry approach developed in the AL 1.01 building of the State Polytechnic of Malang. Calculations performed on the tool are to calculate the value of windings per volt (GPV) and the number of primary and secondary windings. Its manufacture uses a toroid-shaped transformer core. The core specification of the transformer is an outer diameter of 15cm, then an inner diameter of 5.8 cm, and a height of 7cm. The toroid transformer core that will be used is previously isolated from the transformer first to avoid leakage current which can cause heat in the transformer core. The density of the email wire from the transformer winding both from the primary and secondary windings will affect the performance of the transformer, the more tightly the email Wire is wrapped in the transformer core, the vibration generated from the transformer will be smaller, this will affect the voltage losses later in the transformer testing phase carried out using different beaban, each load changes the efficiency of the transformer that has been made will also change, this is because each load tested has different factors.]]>

<![CDATA[The Direct On-Line (DOL) process of starting a high-power 3-phase induction motor causes voltage sags in the distribution system that is connected to one point of common coupling (PCC). Voltage sag can cause damage and failure of sensitive loads. This article analyzes and proposes a simulation of voltage sag recovery using a Dynamic Voltage Restorer (DVR) based on an Artificial Neural Network (ANN). ANN is used as a detector and regulator of the voltage compensation value. In this study, a 3-phase induction motor will be connected to a sensitive load, and the DVR will be placed in series with a voltage source or PCC with a sensitive load. The simulation test system uses Simulink-Matlab R2016a with different configurations of induction motor parameters. Based on the simulation results show that the parameters of the 3-phase induction motor cause the depth and duration of the voltage sag. DVR with ANN control can detect and compensate for a voltage sag of 0.5 pu so that the voltage will be normal to 1 pu.]]>

<![CDATA[The Markov Model analysis is a special probabilistic model commonly called a Stochastic process or a probabilistic change process that occurs continuously. This method is used to analyze the likelihood of disturbances occurring in the following year (2021 and 2022). The reliability of the feeder is assessed based on the duration and frequency of disturbances. The analysis process refers to feeder disturbance data from 2018-2020 using the Markov Model. The results of the analysis are used to determine efforts to improve feeder reliability. In 2021, it is estimated that 70.59% of Mojolegi Feeders will experience disturbances every month with 29.41% of level G disturbances. Meanwhile, in 2022, the percentage of disturbances increased by 1.07% from the previous year with a level G disturbance of 28.63%. This indicates that the Mojolegi Feeder is still prone to disturbances and experiences an increase in disturbance percentage every year. In 2021, it is estimated that 11.43% of Gading Feeders will experience disturbances every month with 25.00% of level G disturbances. Meanwhile, the percentage of disturbances in 2022 is consistent at 11.43% with a level G disturbance of 25.00%. This indicates that the Gading Feeder is still within the safe corridor of disturbances and experiences a constant value every year. From the analysis results, areas prone to disturbances with their causes are obtained. In response to this, PT PLN (Persero) ULP Mojoagung can focus on maintaining the distribution network in areas prone to disturbances. Efforts to improve the reliability of the Mojolegi Feeder can be focused on section V, while efforts to improve the reliability of the Gading Feeder can be focused on section II. This aims to improve feeder reliability at PT PLN (Persero) ULP Mojoagung.]]>

<![CDATA[ Based on the Decree of the Minister of Energy and Mineral Resources (ESDM) Number 0074.K / 21 / MEM / 2015 concerning the Ratification of the 2016-2025 Electricity Supply Business Plan (RUPTL), the load growth every year has increased. Therefore, there will be additional Generating Units with a capacity of 1000 MW at PLTU Paiton, it is necessary to analyze the effect of additional loads in 2017 - 2022 on the 500 KV GITET system before and after the addition of a 1000 MW generator. Based on the analysis, it is known that the additional power of 1000 MW will strengthen the Paiton GITET reserve margin in bearing the load growth, it can be seen from the reserve margin value before the addition of power plants by 16% and after the addition of 29%. For the ability of the Paiton - Grati GITET transmission line until 2022, the load is 62% with a power loss of 35.41 MW (2.85%) and the load on the Paiton - Kediri GITET transmission line is 62% with a power loss of 35.41 MW (2.85%) indicates that the channel still in good shape. In addition, the load condition for the IBT transformer until 2022 is 84%, it can be concluded that the transformer is in good condition]]>

<![CDATA[The length of conductor paths in distribution networks often leads to voltage drop issues and significant network losses. Placing capacitor banks in the distribution network is the primary solution to address these problems. However, optimizing the installation to achieve a significant impact on the voltage level in the network requires complex calculations, especially for very long lines such as in the 20 kV medium voltage network. This paper will use a 20 kV primary distribution system with 10 buses and 9 lines. Based on operational conditions, there are several issues that need to be addressed, and their solutions will be sought through heuristic methods.]]>
