Abstract: A method of identifying a ballistic impact on a power transmission asset is disclosed. 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.
