A method and device for detecting when a clipping component within a transient voltage surge suppressor (TVSS) or TVSS with high frequency electrical noise attenuation (both called surge suppression device or SPD) has failed open. The method comprises the steps of: collecting airborne debris and gases generated when the SPD fails open in a space; subjecting the space to a particle detector; diagnosing the detection of particles by the particle detector and communicating the diagnosis to an appropriate signal generator. The device comprises a container within which at least the clipping components of the SPD reside; an open air space within the container; particle detector associated with the space within the container; and an electronic control unit electronically associated with the particle detector to receive a message that airborne debris or gas particles are within the air space inside the container and then to communicate and, as required, act on such.
