DEVICE FOR SIGNAL PROCESSING IN AN ELECTRICAL INSTALLATION

摘要

The invention relates to a device for signal processing comprising first input means (37) intended to be connected via a measurement sensor (19) to a high-voltage signal of an electrical installation, and processing means (33) intended to analyze the signal measured by said sensor, the device furthermore comprising: - toggling means (41) configured to cause the operation of the device to toggle 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 operative 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 (39) connected to said processing means (33), said processing means being configured so as to actuate said toggling means (41) in such a way that the device operates in test mode or in operative mode according to whether the second input means are activated or deactivated respectively.
