ABSTRACT:
A device for detecting and locating anomalies in the electromagnetic protection of a system including electrical bodies and protective members includes a transmitter of electromagnetic waves. Sensors protected by the protective members pick up an electromagnetic wave transmitted by the transmitter and measure a representative parameter of the wave. A central unit compares the measured values to a value corresponding to a reference state of the protection and on the basis of such comparison detects anomalies in the protection and locates an anomaly according to the suspect sensor.
