Abstract

Human safety against touch voltage hazards is the most important factor in electrical power systems. Touch voltage hazards can occur if a person directly or indirectly touches live electrical parts. Indirect contact can happen when a person touches exposed conductive parts of equipment that are normally not energized but can become energized due to leakage current caused by insulation failure in electrical cables. Therefore, protection against indirect touch voltage is necessary. This study aims to analyze the protection against indirect contact voltage using an Earth Leakage Circuit Breaker (ELCB) and a Miniature Circuit Breaker (MCB). In this study, a 30 mA ELCB and a 2 A MCB were used as protection against indirect touch voltage hazards. The research data were obtained using the experimental method by conducting laboratory experiments. The laboratory experiment results showed that the 30 mA ELCB is more sensitive as protection against indirect touch voltage compared to the MCB. This is because the working principle of the ELCB is based on the leakage current occurring at the exposed conductive parts, whereas the working principle of the MCB is based on the total current (leakage current and load current) flowing through the MCB.

Abstract

The electricity distribution system is essentially a process of delivering electricity from power generation systems to electricity consumers through a 500/150/70 kV Transmission Network to electricity consumers at 20 kV or 220/400 V. The electricity distribution process begins from the output of the 20 kV substation to the consumers. The distribution of electricity when it exits the substation will pass through feeders. Feeders are the pathways for distributing 20 kV of electricity to distribution substations. Feeders are one of the most crucial parts of the electricity distribution process. As the customer load increases and the length of the lines on each feeder, it can cause an increase in current load and voltage drop. According to SPLN 72: 1987 regulations, in medium voltage networks, the spindle configuration voltage drop limit is 2% of the operating voltage. Therefore, feeders experiencing voltage drops must implement feeder splitting methods to reduce voltage drops at the end of the line. By implementing load splitting on the Curriculum and Report feeders by adding a new feeder, namely the Academy feeder, the voltage drop at the end of the lines does not exceed SPLN standards. The Curriculum feeder is at 2.7%, the Report feeder is at 2.06%, and the Academy feeder is at 1.4%.

Abstract

Solar energy is a renewable energy source (EBT) that will never run out. One utilization of solar energy is as a source of solar-powered public street lighting (PJUTS). Public street lighting aims to assist the public when traveling and improve road safety at night. This research will focus on planning solar-powered public street lighting located in Sikeben Village, Sibolangit District, Deli Serdang Regency, which is a provincial road with a width of 5 meters and a length of 3950 meters. At night, several points on the road have minimal lighting, potentially increasing the risk of accidents and crime. Additionally, at some other points, lighting is already installed, but it still relies on the PLN (State Electricity Company) as the power source.The planning of solar-powered public street lighting (PJUTS) requires 158 lighting points with 24 Watt LED lamp loads. With a pole height of 7 meters and a distance of 25 meters between poles, the lighting intensity is calculated to be 6.72 lux manually. According to applicable standards, the value of illumination intensity is 3-7 lux. The solar modules used have a capacity of 75 Wp. PJUTS operates for 12 hours a day and can continue operating for 3 days without solar energy source. The total cost for this solar-powered public street lighting is Rp 1,224,500,000.

Abstract

The hybrid power generation system (solar cells and diesel generator) is one of the alternative solutions to the negative impacts of conventional energy systems on ships in Indonesia. The use of this hybrid power generation system can support the development of environmentally friendly ship technology as global warming issues become more widespread. The advantages of implementing a hybrid power generation system include a reduction in fuel consumption by the generator and a simultaneous decrease in emissions from the ship. Choosing a hybrid system with solar power is particularly advantageous in Indonesia due to its abundant sunlight. This study employs technical and economic analytical methods to design a hybrid power generation system (solar cells and diesel generator). Technical and economic analyses are conducted using a tanker ship as the research object, comparing the hybrid power generation system with the conventional system widely used on ships in Indonesia. The research results indicate that the implementation of a hybrid power generation system on tanker ships results in a 15.5% annual fuel consumption saving compared to the use of conventional power generation systems. Therefore, due to the increased investment costs and reduced operational costs in the hybrid power generation system compared to the conventional system, the break-even point can be achieved in 3.69 years or equivalent to a total nominal cost of Rp 23,980,000,000.00 or $1,803,007.52.

Abstract

Optimal power flow analysis is a calculation to minimize an objective function, namely generation costs or transmission losses by regulating the active power and reactive power generation of each interconnected power system generator by taking into account certain limits. The growth of industrial loads which are dominated by inductive loads requires a fairly large reactive power supply. This reactive power requirement will of course reduce the available power that can be transmitted to the load. Reactive power flow in transmission lines will reduce the active power distribution capacity required by the load. Reactive power flow that is too large can also cause losses. However, this reactive power is also an important component in the stability of the electric power system. For this reason, the flow of active and reactive power in transmission lines needs to be regulated so that the capacity and stability of the electric power transmission system is maintained.

Abstract

The reliability of power transformers heavily depends on the performance of insulating oil, which serves as both an electrical insulation medium and a cooling agent. One of the key factors in maintaining the quality of insulating oil is its breakdown voltage, which determines the oil's ability to withstand electrical stress before insulation failure occurs. The rise in temperature during transformer operation can lead to a decrease in the oil's breakdown voltage, thus affecting the overall reliability of the transformer. This study aims to analyze the effect of temperature rise on the breakdown voltage of power transformer oil. Testing was conducted through simulations and laboratory measurements at various temperatures to identify the relationship between temperature and the oil's breakdown voltage. The results of the study indicate that an increase in temperature significantly reduces the breakdown voltage of insulating oil, thereby increasing the risk of insulation failure and reducing transformer reliability. The conclusions of this study provide essential recommendations for managing transformer operating temperatures to maintain optimal reliability and service life while avoiding potential failures caused by insulating oil degradation.
