Abstract

The present invention refers to a combined device for electrical protection against transient overvoltages and monitoring of an electrical installation, of those used in installations with alternating single-phase or multi-phase current, or direct current, of those formed by cartridges plugged in to a fixed base or formed by a monoblock, both types of devices comprising one or more components for overvoltage protection in each plug-in cartridge or in the monoblock, characterised in that it comprises monitoring means configured so that they continuously measure and process one or several parameters related to the state of the electrical installation and the protective device itself, and connected to said monitoring means a series of indication means configured to indicate one or a combination of output parameters are comprised.

Abstract

The invention relates to a combined device for electrical protection against transient surges, and for the monitoring of an electrical system, of the type used in single-phase or polyphase alternating current systems, or direct current systems, and of the type formed by cartridges that can be plugged into a fixed base, or those formed by a single piece, both types of device comprising one or more components for protection against transient surges in each plug-in cartridge or in the single piece, said combined device being characterised by comprising monitoring means formed such that they continuously measure and process one or a number of parameters relating to the status of the electrical system and to the protective device itself, and said combined device also comprising indication means connected to the monitoring means and configured such that they indicate one or a combination of output parameters.

• H02H 7/00 - Emergency protective circuit arrangements specially adapted for specific types of electric machines or apparatus or for sectionalised protection of cable or line systems, and effecting automatic switching in the event of an undesired change from normal working conditions
• H01H 83/10 - Protective switches, e.g. circuit-breaking switches, or protective relays operated by abnormal electrical conditions otherwise than solely by excess current operated by excess voltage, e.g. for lightning protection
