Abstract
A system and method for ventilating a utility structure enclosed by a vented cover is provided. The system includes at least one air movement device coupled to the cover. A first induction loop is electrically coupled to the at least one air movement device, the first induction loop being coupled to the cover. A second induction loop is disposed in the utility structure, the second induction loop being inductively coupled to the first induction loop. A gas sensor is operably coupled to the second induction loop to direct electrical power to the second induction loop in response to a gas level being equal to or exceeding a predetermined threshold.
