Abstract

This study aims to analyze the process of replacing Fuse Cut Out (FCO) on the 20 kV distribution network at PT. PLN (Persero) UP3 Cikupa to enhance the reliability of the electricity distribution system. Fuse Cut Out (FCO) is an essential protective device designed to prevent damage to electrical equipment from overcurrent or short-circuits. In the 20 kV distribution network, FCO often experiences reduced functionality due to aging and environmental conditions. This research evaluates the current condition of FCOs and implements precise and safe FCO replacement procedures. The method used is a descriptive qualitative approach, with data collected through literature review, interviews, field observations, and FCO performance testing. The research findings indicate that placing an arrester after the FCO provides additional protection for transformers, selecting fuse link ratings in accordance with transformer capacity is crucial for effective protection, and proper coordination of fault current interruption significantly improves system reliability. These findings are expected to assist PT. PLN (Persero) in optimizing FCO replacement procedures to reduce disruptions and extend the operational life of distribution equipment.

Abstract

Electrical energy is one of the main resources that is very much needed in everyday life and is an important indicator of a country's progress. The electric power distribution system plays an important role in ensuring efficient and reliable energy supply to consumers. Electricity distribution starts from power plants, through transmission and distribution networks, until it reaches the end consumer. This distribution process involves various components, such as substations, power transformers, and distribution lines that adjust the voltage according to consumer needs. This study aims to analyze the operation of the distribution system from medium voltage to low voltage at the Serang Main Substation, with a focus on reducing power losses, improving distribution quality, and minimizing system disruptions. The research methods used include literature studies, observations of existing distribution systems, and interviews with experts in the field of electricity distribution. The results of the study show that distribution efficiency can be improved with better load management, capacitor installation, and the application of modern technology in the distribution network. Thus, a more efficient electric power distribution system can provide significant benefits to consumers and energy providers, reduce power losses, and improve overall system reliability.

Abstract

The 20 kV cubicle plays a vital role in the electrical distribution system, particularly in maintaining the reliability and stability of power supply for industrial customers. This study aims to evaluate the impact of routine maintenance on the performance of 20 kV cubicles at the Prima Krakatau Customer Service Unit (ULP). Maintenance is carried out periodically using time-based and condition-based approaches and includes measuring technical parameters such as grounding resistance, Current Transformer (CT), and Circuit Breaker (PMT). The results indicate that all components are operating optimally, with grounding resistance at 0.6 ohms and resistance values for CT and PMT exceeding 50 GΩ. The study concludes that scheduled cubicle maintenance contributes to improved power distribution reliability, reduced risk of system interruptions, and enhanced customer satisfaction.

Abstract

Accurate temperature monitoring in the furnace is an important element in the processing of steel metals at PT Krakatau Baja Construction. Type S thermocouple sensors are used to measure temperature by converting temperature changes into voltage signals. However, to ensure the accuracy of the readings, thermocouple performance verification is carried out periodically. This research aims to verify thermocouples in several furnace zones to increase the accuracy of temperature data in the Human Machine Interface (HMI) system. The verification process uses the Fluke 17 B+ tool and Universal Transmitter PR4116. The measurement results are compared with the reference table and HMI readings before and after verification. The results show that all thermocouples function well with the largest deviation of 23°C in Zone 2A before adjustment and the smallest deviation of 1°C in Zone 1. Verification succeeded in reducing the deviation, ensuring the reliability of the measurement system. This research confirms the importance of thermocouple verification to improve production efficiency and product quality, with recommendations for regular evaluation of the HMI system and temperature measurements.
