Abstract
Telah dilakukan penelitian analisis distribusi medan magnet di daerah sekitar Gardu Induk (GI) PT PLN (Persero) P3B Sumatra, Teluk Betung Selatan, Bandar Lampung. Gardu Induk (GI) berfungsi untuk menyalurkan tenaga listrik dari sistem transmisi listrik ke distribusi konsumen. Hal tersebut menyebabkan timbulnya medan magnet di sekitar peralatan instalasi listrik dan sekitar kawat berarus yang ada di GI. World Health Organization (WHO) dan SPLN menetapkan baku mutu medan magnet, yaitu 1000 μT, sementara Kemenkes dan SPLN menetapkan baku mutu medan magnet, yaitu 5000 μT. Berdasarkan hasil penelitian pengukuran medan magnet dengan Milli Gauss Meter GU-3001 pada waktu pagi, siang, dan malam hari (beban puncak) menunjukkan bahwa waktu penyaluran daya listrik berpengaruh terhadap besarnya medan magnet dan nilai yang ditimbulkan masih dalam ambang batas baku mutu medan magnet. Nilai medan magnet tertinggi, yaitu 10,71 μT (arus searah DC) dan 3,42 μT (arus bolak-balik AC). Nilai tersebut adalah hasil pengukuran medan magnet pada waktu malam hari (beban puncak) yang masih di bawah baku mutu medan magnet. It has been conducted research about analysis of magnetic field distribution in the area of the substation of PT PLN (Persero) P3B Sumatra, South TelukBetung, Bandar Lampung. The substation serves the distribute of electric power from electricity transmission system to consumer distribution. It caused the magnetic field around the electrical installation equipment and the current carrying wires that are on the substation. World Health Organization (WHO) set a quality standard for magnetic field was 1000 μT, while the Ministry of Health and SPLN set a quality standard magnetic field is 5000 μT. Based on the results of measurement with Milli Gauss Meter GU-3001 in the morning, afternoon, and evening (peak load) shown that the timing of the distribution of electric power affected the magnitude of the magnetic field. The maximum value of the magnetic field was 10,71μT (direct current DC) and 3,42 μT (alternating current AC). This value was the result of measurement of magnetic field at night time (peak load) that still below of quality standard the magnetic field. Keywords : Electric current, magnetic field, substation, WHO.
