Abstract

In this study, data were collected on solar irradiation (W/m2), short circuit current (Isc), and open circuit voltage (Voc) at angles of 10°, 20°, 30°, 40°, 50°, and 60°. The research method used is an experimental method of data collection with variations in the tilt angle of the solar panels. From the results of research that was tested using monocrystalline solar panels with a capacity of 50 WP, it can be concluded that the highest value of the solar panel output power (Pout) was 31.59 Watts at an angle of 10° which occurred at 01.00 p.m. Then the highest efficiency value (η) of 15.47% occurred at 03.00 p.m. with a slope angle of 10º.

Abstract

The high content of harmonics in an electric power system can cause several disturbances to the system, such as increasing power losses in the system, causing various damage to electrical equipment, and causing the use of electrical energy to be ineffective. Harmonics is caused by the operation of non-linear electrical loads. The interacting harmonic currents with the supply system impedance distorts the supplier's output current and voltage which in turn adversely affects the loads connected to the system and the supply itself. This study aims to analyze the quality of THD in Bubung Tujuh Hamlet, Sangku Village. In this study, THD measurements were carried out and analyzed the effect of harmonics on the power factor using a linear regression test. The results of the measurement and analysis of THDV ranged from 1.0% - 6.8%, with the final analysis of THDV still meeting the set standard of 5%. THDI ranged from 2.3% - 66.7% with the final analysis THDI did not meet the standard. THD of the village's electrical system is still at the standard limits set and THD(V) effect on PF.

Abstract

Electricity in Indonesia, especially in the Bangka Belitung Islands, has been affected by the COVID-19 pandemic. The effect occurred at the beginning of the pandemic in the second quarter of 2020, namely the household sector rose to 3.3%, the social sector fell -3.1%, the industrial sector rose to 15%, business fell -9.8%, the office sector government buildings rose 3%, and the public/other street lighting sector fell -47%. By using statistical tests on the classical assumption test all sectors are normally distributed. In the partial test using multiple linear regression test for the household sector, industry, and government office buildings, only connected power affects energy consumption, namely 70.5%, 97.7%, and 37.4%. In the social and business sectors, there is an effect of connected power and tariff prices on energy consumption, namely 92% and -13%, while business is 42% and 10%, respectively. By using the simultaneous test, the household sector has an effect of 68.2%, the social sector is 75.5%, the industrial sector is 97.5%, the business sector is 44.2% and government buildings are 32.5%.

Abstract

This study evaluates the performance of 20 kV circuit breakers by analyzing insulation resistance, contact resistance, contact synchronization, leakage current, and power loss. The insulation resistance analysis indicated that phases R and S did not show significant improvement after maintenance, with significance values of 0.065 and 0.166, respectively, while phase T exhibited a significant improvement with a significance value of 0.048. Contact resistance measurements revealed no statistically significant reductions after maintenance, with significance values of 0.209, 0.243, and 0.155 for phases R, S, and T, respectively. Additionally, contact synchronization in the open condition did not experience significant variations, whereas in the closed condition, all phases showed significant declines in synchronization after maintenance, with significance values of 0.003, 0.013, and 0.007. Leakage current analysis at a 20 kV phase-to-ground voltage showed that the highest recorded leakage current was 0.297 mA in the Eks Sumberejo feeder, significantly below the 20 mA threshold. Power loss calculations identified the highest power dissipation in the Depati Hamzah feeder at 69.87 W, with the lowest in the Eks Transmart feeder at 0.376 W. Energy loss assessment further showed the Depati Hamzah feeder experiencing the highest loss at 48.317 kWh, while the Eks Transmart feeder had the lowest at 0.278 kWh. These findings underscore the importance of routine monitoring and targeted maintenance to enhance circuit breaker reliability, optimize operational efficiency, and minimize energy losses in high-voltage electrical networks.
