Abstract: A signal processor device comprising: first input means intended to be connected, via a measurement sensor, to a high-voltage signal of an electrical installation; and processor means for analyzing the signal measured by said sensor; the device further comprising: changeover means that are configured to cause the operation of the device to change between a test mode in which the device is disconnected from said high-voltage signal so as to be connected to a test signal, and an operating mode in which the device is disconnected from said test signal so as to be reconnected to said high-voltage signal; and second input means that are connected to said processor means, said processor means being configured to actuate said changeover means so that the device operates in test mode or in operating mode depending on whether the second input means are activated or de-activated respectively.

Abstract: The invention relates to a device for measuring temperature in a high-voltage portion of a switchgear station, characterised in that it comprises: at least one temperature sensor (21, 22, 23, 24) located at a point on the high-voltage portion of which the temperature is to be monitored, at least one antenna (25) connected to the at least one temperature sensor, a control module (26) located in a low-voltage portion of the switchgear station, and at least one antenna (27) connected to the control module. The at least one temperature sensor (21, 22, 23, 24) is suitable for transmitting a signal representative of a temperature measurement and the control module (26) is suitable for receiving the representative signal, via the antennas, and for processing said signal in order to produce a message.
