Abstract

Short circuit fault analysis is needed to determine the amount of short circuit current flowing in a system. This study discusses the single-phase short-circuit current to the ground at the point where the disturbance occurs from the base of the network to the end of the Malewang feeder network. The purpose of this study was to determine the amount of short circuit fault current in the Electric Power Distribution System at PT PLN (Persero) UP3 South Makassar ULP Kalebajeng. This study used the ETAP program and manual calculations. The results of the study found that the contribution of the largest single-phase short-circuit fault current to the ground in the Malewang feeder occurred on Buses located at the base of the network close to the Substation, namely Bus 1 (Exim-Rec Kalaserena) of 0.311 kA, while thesmallest Buscontribution occurred on Buses located at the end of the network far from the Substation, namely Buses 14 (Bilonga) of 0.292 kA. From the results of the study, it can be concluded that the farther the interference bus is from the Substation, the greater the channel impedance. The greater the impedance, the smaller the short-circuit current.

Abstract

This study analyzes the reliability of the control system at the UPDK Tello Gas Power Plant (PLTG) with a focus on critical components that affect systemperformance. The evaluation was conducted using three main indicators: availability, Mean Time to Failure (MTTF), and Mean Time to Repair (MTTR), andtheir impact on operational efficiency. Quantitative descriptive research method was applied through Failure Mode and Effects Analysis (FMEA) analysis, direct observation, and maintenance document study. The results showed variations in reliability between components. In GE#1, the TCDA card has the highest RPN value of 156, availability 0.9995435874, MTTF 13139.99999 hours, MTTR 5.999999999 hours, reliability 0.1353352832, and operationalefficiency 99.95431704%. At GE#2, the exhaust thermocouple has the highest RPN of 192 with a reliability of 0.04978706857, while the 1.5 A fuse has the lowest availability of 0.9994675591, MTTF of 26279.99999 hours, MTTR of 14 hours, and operational efficiency of 99.94672755%. The average operational efficiency at GE#1 and GE#2 are 99.9866758% and 99.98731608% respectively. The results show that the system still meets operating standards although there are significant differences between the RPN values and other reliability indicators. Components with high RPN do not always have the lowest availability or operational efficiency. This research emphasizes the importance of a multi-indicator approach in reliability analysis as well as the need for customized maintenance strategies for each critical component.
