Electricity from sunlight can be generated through energy conversion in solar cells. Although this process is effective, it may experience a decrease in performance due to the increase in thermal energy, elevating the surface temperature of solar cells. Solar panels, composed of solar cells arranged both in series and parallel configurations, are responsive to temperature fluctuations. The rise…
Power factor is one of the problems in improving the quality of electric power. This problem can be overcome by improving the power factor value by installing a capacitor bank. Adding a capacitor bank capacity value of 240 kVAr and capacitor capacitance of 4.2972 μF can improve the power factor in the system by up to 0.89 - 0.99 lag. Keywords: Capacitor bank, current, apparent power, reactiv…

Apart from the aspect of good city governance, Pekanbaru City is seen as still holding tightly to the culture, customs and arts of Riau Province. This research aims to design an electrical system according to appropriate standards, calculate the electrical power requirements needed for the Pekanbaru C…
The type of electric motor commonly used in industrial activities is the induction motor. The use of induction motors reaches 95% as a prime mover and utilizes up to 40-50% of all electrical energy produced by power plants. Although induction motors are very reliable with a low failure rate and only require basic maintenance, they can sometimes break down and fail. . Detecting problems early an…
This research analyzes the calculation of capacitor bank values to repair the voltage drop that occurs on the TG5-6 3.3kV bus at PT Indah Kiat Pulp and Paper of 0.06pu. The voltage drop standard that is set is 0.05 pu or 5% (ANSI C84.1-1995). The analysis is carried out based on power flow by modifying the bus load type (PQ) to become the controller bus voltage (PV). Assuming that the bus load …
This research aims to minimize the frequency and duration of outages at points unaffected by disturbances through maneuvers. It also seeks to determine the reliability level of the distribution network in the Munchen feeder before and after the maneuvers. The study involves analyzing the maneuvers in the Munchen feeder to assess the reliability of the distribution network, including both SAIFI …
Induction motors are the most common type of electric motor used in the industrial sector throughout the world. The use of induction motors reaches 95% as the main mover and utilizes up to 40-50% of all electrical energy produced by power plants. However, although induction motors are very reliable with a low failure rate and require only basic maintenance, they can sometimes break down and fai…
The distribution substation is a distribution system whose function is to distribute the network to consumers, both medium voltage consumers and low voltage consumers. In distribution there is always a problem, namely load balance. As a result of loose loads in a distribution system, there is the emergence of a neutral current, the current flowing in the neutral transformer will cause power los…
The imbalance of loads in the distribution transformer always arises due to uneven electricity usage. The consequence of this load imbalance is the flow of current in the neutral conductor of the transformer, leading to losses. Other losses in the transformer include power losses, core losses, and copper losses. Problem analysis using a mathematical model involves calculating the percentage of …
Roads are a vital means that need serious attention, so that the activities of people in a city can improve. Jalan Jenderal Sudirman is an area with orderly traffic and currently Jalan Sudirman has quite heavy traffic flow. As one of the arterial roads, road equipment facilities are certainly needed on this road. Therefore, the author is interested in analyzing the road equipment on Jalan Jende…
Road damage is one of the things that must be addressed at this time, one of which is on Jalan Garuda, Marpoyan Damai District, Pekanbaru City, Riau Province, with a road length of 1,600 meters and a road width of 6 meters, making it uncomfortable for motorists passing through the road, so repairs are needed. a path that starts with knowing the types of damage that exist. The aim of this rese…
