Electricity losses are very dependent on electric current and loss of the corona phenomenon. It is very clear that losses depend on network parameters, load behaviors and climatic factors. South Sulawesi is a tropical climate. This sector must be resistant to exposure to various factors of high tropical climate such as temperatures of 23.4⁰C - 33.3⁰C, sun irradiation that occurs more than 12 hours per day, relative humidity close to 100%, and average rainfall between 440-1322 mm . This climate factors will simultaneously transmit the transmission. This text aims to connect climate factors to achieve power losses on 275 kV transmission line in South Sulawesi. The results of this study found that temperature and duration of sun irradiation affected corona power losses on 275 kV transmission line in South Sulawesi.

Straty elektryczne są bardzo zależne od prądu elektrycznego i zjawiska korony. Oczywiste jest, że straty zależą od parametrów sieci, obciążenia i czynników klimatycznych. South Sulawesi to tropikalny klimat. Sektor ten musi być odporny na działanie różnych czynników tropikalnych, takich jak temperatura 23C - 33C, promieniowanie słoneczne, które występuje więcej niż 12 godzin dziennie, wilgotność względna bliska 100%, a średnie opady wynoszą 440-1322 mm. Niniejszy artykułma na celu analizę czynników klimatycznych w celu uzyskania strat mocy na liniach przesyłowych 275 kV w Południowym Sulawesi. Wyniki adania pokazały, że temperatura i czas trwania promieniowania słonecznego wpłynęły na straty energii z wyładowań koronowych.

The power system consists of generating units, transmission lines and distribution networks. The transmission network is considered as the backbone of the electric power system that connecting the power plant center with the load center. In general, the transmission line carries an electric current that reach hundreds of kilometers. The entire transmission system is interrelated due to economic reasons, security and reliability which is a transmission line requirement based on system planning . Every time the generating unit is added to the system, there is a need for a transmission line to transfer power from the generating station to the load center. But the longer the transmission line is used, the greater the electrical power losses in the transmission line so that the electrical power that reaches the destination has been reduced which causes the transmission line efficiency to be low and the transmission line voltage regulation becomes high. To avoid this, the option is to increase the voltage on the transmission line from high voltage level to extra high voltage. Therefore, one of the efforts to reduce electric power losses and improve the quality of stress in the province of South Sulawesi, one of the provinces in the country of Indonesia, or often called the South Sulawesi system, is insertion of 275 kV transmission network. In addition to these reasons, the application of the 275 kV transmission line is to connect power plants in the area of renewable electricity to the load center in South Sulawesi, namely the City of Makassar (the capital of South Sulawesi province). South Sulawesi has many primary energy sources, especially in the form of hydropower which can be developed into hydroelectric power plant. Hydropower potential that can be developed into around 1996 MW . Indonesian, especially South Sulawesi, is on the equator line having a tropical climate, precisely the wet tropical climate. This is also [...]
