The device (100) has a conversion circuit (101) for receiving an input signal representative of the state of equipment, and converting the input signal into a synchronous digital modulated signal whose average value over time is proportional to the amplitude of the input signal input. A comparison circuit (103) is intended to compare the average value of the modulated signal with a reference value, and to produce a status indicator signal if the comparison result matches a predetermined criterion. Independent claims are also included for the following: (1) a protection and control system for energy generation, transmission and distribution (2) a state acquisition method for monitoring the state of equipment in a protection and control system for energy generation, transmission and distribution. |
