Abstract :
This Analysis was conducted to improve the resistance value of the earth system at the foot of the tower 150 KV high Voltage network along the tower installation lane in the Puoomas-Gambir area of 32 towers. Low foot resistance is useful as a shortcut to reduce the lightning current, transmission foot resistance is set to less than 10 Ohm. Prisioners that exceed this value don?t guarantee the safety of the air duck protection, back flashover is very likely to occur in this situation. Puoomas-Gambir 150 KV Transmission tower foot resistance experience change in ground resistance due to changes in in these parameters some transmission towers have foot resistance more than 10 ohm. Offorts made by PT.PLN to reduce prisoners are conducting surveillance and routine ground maintenance. SUTT 150 KV tower measurement in pulomas-Gambir
