High Voltage Conductor Effect Estimation on The Nearby Buried Piping System

Nowadays, space between utility and industrial infrastructure has become closer and closer due to the shortening of land availability. In those circumstances, the possibility of a new HV line will be installed near another facility like the mining area, industrial area, and business area will increase. This issue needs to be considered carefully since HV lines could affect the metal structure near them. HV lines can induce voltage to the metal structure nearby, causing AC stray current flow that leads to corrosion acceleration in the structure and also leave a potential shocking hazard to human and animal around the metal structure. Hence, a calculation of the affected effect by the HV line needs to be conducted to plan proper mitigation. This paper introduces a simple method to calculate induced voltage to the structure nearby. It is developed to estimate induced voltage in a piping system near the upcoming plan to energize a newly installed HV line in Jakarta.
