High Voltage AC (HVAC) Risk Management

High Voltage AC Infrastructure risk

North America, there are over three million high voltage alternating current (HVAC) towers and twenty thousand power lines over 220kV. These external elements present a safety risk to pipeline integrity. Research has shown increases in voltage induced on the pipeline resulting in an increased probability of failure due to external corrosion growth and difficulty managing cathodic protection systems : North American High Voltage AC Infrastructure The risk comes in the form of capacitive, inductive, and resistive coupling from the HVAC assets. Each coupling method suggests a unique geospatial susceptibility analysis and mitigation recommendation. This susceptibility analysis considers inductive and resistive coupling only.
