Abstract

Generally, the configuration of the substation grounding system is in the form of a grid or mesh, where several conductor rods are installed vertically and horizontally or combined with conductor rods planted deep in the ground from each point or not. The substation configuration is very complex because of the many variables used in accordance with IEEE Standard 80-2013. This variable also influences the allowable and actual magnitude of the step voltage and touch voltage. The substation grounding system configuration can be designed in several shapes including rectangular, square, L-shaped and T-shaped. The parameters used are an area of 70 m x 70 m, a conductor rod depth of 0.5 meters with a total conductor length for a rectangle of 1540 meters without rods, an L-Shaped shape of 1755 meters and a T-Shaped shape of 3857 meters. The results obtained by the resistance of the grounding system without rods in the T-Shaped configuration were 2.39 Ω. For the resistance results, the grounding system uses a rod with the same area and a conductor length of 3917 meters with a resistance value of 2.39 Ω in the T-shape configuration. The results of the resistance values obtained with various forms of grounding system configurations and varying conductor lengths are still safe and below the threshold or standard of the grid grounding system.

Abstract

This study analyzes the impact of lightning strikes on the NDB JTM-30C equipment at the Jakarta Air Traffic Services Center (JATSC). NDB equipment is used in flight navigation, but lightning strikes can disrupt operations and flight safety. Data on lightning strikes and disturbances to the NDB were collected and analyzed. The results show a relationship between the frequency of lightning strikes and disturbances to the NDB. These disturbances can affect signal quality, cause temporary outages, or result in permanent damage to the equipment. The potential impact poses risks to flight safety and operational performance. Mitigation measures, regular maintenance, and early warning systems should be implemented to reduce the risks of disturbances caused by lightning strikes. This research provides a better understanding and a foundation for effective mitigation strategies to enhance flight safety.

Abstract

In knowing how efficient the use of the Star Delta circuit is, the need for a circuit on a 3 Phase motor and how to apply the circuit to a 3 Phase water pump motor. The research was conducted at Gorontalo Djalaluddin Airport which is located in Isimu Sel, Tolotio, Tibawa District, Gorontalo Regency, Gorontalo, Indonesia. The research was carried out using data collection methods. An example of the application of a star delta circuit to a water pump motor. An electric motor is included in the category of dynamic electric machines and is an electromagnetic device that converts electrical energy into mechanical energy. Electric motors in the industrial world are often referred to as the industrial "work horse" because it is estimated that in an industry the average electricity consumption for electric motors is around 65-70% of the total electrical load in the industry. Three-phase electric motors have initial current characteristics that are 5 to 7 times the nominal current of the electric motor itself, but can be overcome by a star (Y) - triangle (Δ) starting system. The aim of this study was to examine how the triangular (Δ) star (Y) starting system works for 3 phase induction motors. The methods used include literature studies, collection of tools and materials, design, tool testing and data collection. From the results of testing the triangular (Y) star starting system (Δ) effectively suppresses the high starting current of the electric motor operation with the value of the measurement results of electric current using a star connection (Y) in the R phase of 0.6 A, the S phase of 0.8 A and the T phase of 0.6 A. And using a triangular relationship (Δ) in the R phase of 7.5 A, the S phase of 8.5 A and the T phase of 8.3 A.

Abstract

This research aims to analyze the condition of parking lights that use renewable energy, namely solar cells. Basically, the condition of the parking lights is not working optimally or not in accordance with the predetermined light on time settings due to the lack of power supplying the parking lights, resulting in a lack of live time for the solar cell parking lights. Data on the equipment module used in the solar cell parking lights is collected and real data in the field or manual measurement data will then be analyzed. The results will be a comparison between the data in the tool module and the measurement data in the field. The impact is the lack of lighting in the parking area of Sumbawa's Sultan Muhammad Kaharuddin Airport. Equipment checking and routine maintenance must be carried out to resolve problems that occur with parking lights. This research provides a better understanding of renewable energy, namely solar cells.
