Abstract: Electrical protection systems and methods, of which an exemplary method comprises: measuring a voltage and an electric current in an electric link; calculating, repeatedly, from the measured values of current, a first moving average and a second moving average, the second moving average being calculated over a duration longer than the first moving average; comparing the measured voltage value with a predefined voltage threshold value; comparing the current value of the first moving average with the current value of the second moving average; and identifying a condition of trigger of the protection device when the measured voltage value is lower than the predefined voltage threshold value for a duration longer than a predefined duration threshold and when the current value of the first moving average is higher than the current value of the second moving average.

Abstract: 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.

Abstract: A method for monitoring an electric power source changeover switch, including a step of identifying all of the combinations of operating modes and availability states of the power sources, a step of associating a configuration of a state of switches with each combination, a step of watching for a change in configuration. Upon a change in configuration, a step of controlling the switches is executed in order to place the switches in a state complying with the configuration. In the absence of a change in configuration, a step monitors the compliance of the configuration with the actual state of the switches. A method further including monitoring a source changeover switch implemented in a test device, and to a source changeover switch implementing such a method.
