摘要： A system for detecting an object approaching and/or impacting electrical equipment is disclosed. The system includes a housing for the electrical equipment and acoustic sensor(s) for measuring a sound pressure of the object approaching the housing, the acoustic sensor(s) disposed at a location at which the acoustic sensor(s) is not in contact with the housing. The system further includes vibration sensor(s) for measuring an acceleration of a surface of the housing caused by the object striking the housing, the vibration sensor(s) disposed at a location at which the vibration sensor(s) is in contact with the housing, and a computer readable storage medium having thereon machine-readable instructions that when executed determine the approach of the object for impact on the housing and/or the impact of the object to the housing.
