The generated electricity is then channeled through the transmission line. In the distribution of electric power, there will be a channeling power losses which are proportional to the length of the channel. The use of a higher voltage level is the solution to these problems, but if the voltage is increased continuously there will be a corona and to reduce the environmental impact of the corona can use a file conductor. Increasing the amount of conductive wire in a beam reduces the corona effect and reduces reactance, reducing reactance due to an increase in GMR from the conductor. Elevation of the voltage on the electric power transmission line can reduce power losses, but the transmission voltage increase can cause corona in the transmission wire. This corona causes power losses and interference with radio communications. One way to reduce the corona effect is to use a condenser file on the transmission line. Besides reducing the corona effect, the beam conductor can also reduce the channel's inductive reactance. From the results of the study, the results show that the distance between the file sub conductors affects the size of the GMR of the file conductor, where the distance between the file sub conductors is greater, the GMR of the conductor will increase. With the increasing size of GMR conductor, the inductive reactance on the transmission line will be even greater. With the increasing conductivity of the beam conductor reactance, the reactive power losses on the transmission line will be even greater. Listrik adalah sumber energi yang sangat dibutuhkan oleh masyarakat dan listrik merupakan salah satu kebutuhan yang paling penting untuk menunjang kehidupan manusia saat ini dalam memenuhi kebutuhan sehari-hari, baik dalam rumah tangga maupun dalam bisnis. Untuk memenuhi kebutuhan tenaga listrik tersebut, maka pemerintah membangun pusat-pusat pembangkit tenaga listrik.

Penggunaan tingkat tegangan yang lebih tinggi merupakan solusi dari permasalahan tersebut, tetapi jika tegangan ditingkatkan terus menerus akan terjadi korona dan untuk mengurangi dampak lingkungan dari korona tersebut dapat menggunakan konduktor berkas. Peningkatan jumlah kawat penghantar dalam suatu berkas mengurangi efek korona dan mengurangi reaktansi, pengurangan reaktansi disebabkan oleh kenaikan GMR dari konduktor. Peninggian tegangan pada saluran transmisi daya listrik dapat mengurangi rugi-rugi daya, tetapi peninggian tegangan transmisi dapat menimbulkan korona pada kawat transmisi.

Power losses in the distribution network are caused by the presence of prisoners in the carrier. The lost power can be in the form of heat energy generated on the channel, and unused heat energy is called active power losses. Power losses in each channel are very important to take into account because power losses in the network can cause a reduction in electrical energy after arriving at the load. Power requirements that must be supplied by the source to the load depend on the absorption of power by the load and power losses on the network. Large capacity of power requirements is influenced by the amount of power losses, so it can be said that the capacity of power needs is the amount of absorption of power by the load and power losses on the network. One of the substations in the city of Palembang is the Bungaran Substation which has the function of delivering electrical energy to consumers through a medium voltage distribution system. To serve consumers electrical energy needs, currently the Bungaran Palembang Substation has a Transformer 1, 30 MVA 70/20 kV which has a load of four feeders, namely: Akasia Feeder, Sungkai Feeder, Tembesu Feeder, and Cendana Feeder. The results showed that Transformer 1 had an installed power capacity of 30 MVA or 255,000,000 Watts. While the capacity of the total power requirements of the four feeders is 18,786,167.4264 W. So the availability of transformer 1 power is still sufficient to serve the load of four feeders, because only 7.3671% of the installed power capacity is absorbed by the load. Rugi-rugi daya adalah kehilangan daya listrik di jaringan dan beban dimana daya yang hilang tersebut tidak terpakai oleh beban, sehingga daya yang tersedia di jaringan akan berkurang. Rugi-rugi daya pada jaringan distribusi disebabkan oleh adanya tahanan pada penghantar. Daya yang hilang dapat berupa energi panas yang ditimbulkan pada saluran, dan energi panas yang tidak terpakai disebut sebagai rugi-rugi daya aktif. Rugi-rugi daya disetiap saluran sangatlah penting untuk diperhitungkan karena rugi-rugi daya di jaringan dapat menyebabkan berkurangnya energi listrik setelah sampai di beban. Kebutuhan daya yang harus disuplai oleh sumber ke beban tergantung pada penyerapan daya oleh beban dan rugi-rugi daya di jaringan. Besar kapasitas kebutuhan daya dipengaruhi oleh besarnya rugi-rugi daya, sehingga dapat dikatakan bahwa kapasitas kebutuhan daya merupakan jumlah penyerapan daya oleh beban dan rugi-rugi daya di jaringan.

In this observation, we obtained that the bottle will defend or unexpand if it is filled with water in a temperature of ±65°c. This temperature will be used as reference in a water temperature control by using thermocouple sensor. The control system works by monitoring the heater activites in order not to heat the water more than the deterimined setpoint temperature, which is 60°c. In the control process, a thermocouple sensor is supported by PLC Schneider Modicon TM221M16R. The communication process between the thermocouple sensor and PLC utilizes analog input in PLC device. Generated voltage by a thermocouple in the effect of temperature difference between hot junction and cold junction is read by PLC. Generated voltage in the effect of these two points difference is very small, about 40μV/°c. Therefore, IC op amp LM 358 is used as a voltage amplifier.
