The method includes the steps of deploying a sensor assembly at the power transmission asset; using the sensor assembly to receive and process data at the power transmission asset; using an algorithm to compare the processed data to known data and determine if a ballistic impact has occurred on the power transmission asset; and triggering an alarm if a ballistic impact has occurred and dispatching personnel to the power transmission asset.

Abstract: An apparatus and method for identifying physical security risks to power transmission structures and other associated assets of a power transmission system is disclosed. The apparatus includes a sensor having a sensor assembly; and a floating electrode electrically connected to the sensor and positioned adjacent to the asset being monitored.
