Abstract

Lightning is a natural phenomenon that can cause damage to transmission lines and cause disturbances in the distribution of electrical energy. Indonesia is a country with a high density of lightning strike in tropical areas such as in Java Island (Indonesia). The 500 kV Depok-Tasik transmission tower is part of the West Java interconnection. This transmission is 142 kms away and is supported by a tower of 340 units (tower 326-666), this transmission uses dual channels. This study aims to analyze and determine the method of lightning protection and to determine the magnitude of the voltage arising from a lightning strike in the 500kV transmission tower Depok-Tasik in order to be able to see the transmission parameters of the lightning density map, the trend of the time of the strike and the peak current frequency of the overvoltage caused by the lightning strike by analyzed using software falls. Software falls is a lightning analysis software used to study the relationship between lightning events and geographically referenced assets. Anomaly data on the 500kV Depok-Tasik conductor in 2021-2022 occurred 12 times, disturbances occurred 6 times in 2021 and 6 disturbances occurred in 2022, this can be a reference for asset inventory in the future.

Abstract

Solar photovoltaic is a renewable energy that has great potential and is quite cheap. However, solar cells are sensitive to temperature through the parameters of their semiconductor materials. The optimal solar photovoltaic temperature range is 25◦C- 40◦C. Based on the study, the optimal temperature of the solar photovoltaic system is 41◦C. The problem is that solar photovoltaics do not produce power optimally when the surface temperature reaches 41◦C so the power produced decreases. The cooling system is one solution to overcome temperature problems in solar photovoltaics. The purpose is to design an automatic cooling system based on water and air spray using Arduino Uno which operates only at solar photovoltaic surface temperatures above 41◦C and compare the working effectiveness of the cooling system using water spray and air when the surface of the solar photovoltaic reaches maximum heat and does not work optimally. Methods. Design and develop a water and air-spray-based cooling system using an experimental process. Results. The automatic cooling system has been designed using a water spray cooling method and a DC fan-based air cooling method. The water spray cooling method can reduce the temperature optimally with an average temperature of 38.67◦C and the air cooling method can reduce the temperature optimally with an average temperature of 39.5◦C. The water spray cooling method had an efficiency value of 36% and the DC fan-based water cooling method had an efficiency value of 16%.
