VERFAHREN ZUM ERKENNEN EINER ELEKTRISCHEN STÖRUNG, VORRICHTUNG ZUR UMSETZUNG DIESES VERFAHRENS UND ELEKTRISCHES GEHÄUSE, DAS MIT EINER SOLCHEN VORRICHTUNG AUSGESTATTET IST

摘要

A method for detecting a fault with electrical hardware installed in an enclosure. The method includes a step of measuring the concentration of volatile organic compounds, of microparticles and of gases. The measurements are corrected on the basis of climate data and then calculations of drift and change of concentration are performed. An alarm is emitted when a set of drift or change of concentration thresholds are crossed. A device implementing the method and to an electrical enclosure equipped with such a device.
