Abstract


Abstract—  To be able to secure and safety the equipment and the workers who work in the power plant area PLTP Lahendong with power capasity 2 x 20 MW, of course, required the earthing system design quality, reliable and efficient whereby the grounding grid resistance, voltage step and touch voltage according to the calculations contained in IEEE Std 80 -2000. This research will discuss the evaluation of system design with respect to the value of earthing resistance grounding grid, mesh voltage and step voltage. Evaluation parameters - parameters according to calculations published in IEEE Std 80-2000. Results from this study system grounding of PLTP Lahendong unit 5 and 6 well the categorized and meet the standart.

Keywords: Resistance grounding, step voltage, spacing between parallel conductors, touch voltage,.

Abstrak­— Sistem pentanahan yang berkualitas, handal dan efisien adalah merupakan persyaratan utama dalam merancang suatu sistem pentahanan untuk dapat mengamankan peralatan dan para pekerja di area pembangkit. Penelitian ini bertujuan untuk menganalisis desain Grid Pentanahan PLTP Lahendong Unit 5 dan 6 dengan kapasitas daya 2x20 MW berdasarkan metode  IEEE  Std 80-2000. Analisis dilakukan terhadap beberapa parameter berupa luas penampang konduktor, nilai tahanan grid pentanahan tegangan sentuh dan tegangan langkah. Hasil dari penelitian menunjukkan bahwa sistem pentanahan pada PLTP Lahendong Unit 5 dan 6 dikategorikan baik dan memenuhi standar.

Kata Kunci : Jarak paralel antara konduktor, Tahanan tanah, Tegangan langkah, Tegangan sentuh.
