An integrated fault monitoring apparatus for electrical devices has an internal fault detector for detecting transient pressure surges within the electrical device, a pressure relief valve for allowing release of pressure during normal operating conditions of the electrical device, a temperature indicator for indicating that an operating temperature of the electrical device has gone above a predetermined threshold, and/or a sudden pressure relief device for allowing air to escape from the electrical device in the event of a sudden and significant increase in pressure within the electrical device. Methods of using the apparatus are provided.
