Abstract

IN ORDER TO DETECT TAMPERING IN A UTILITY METERING ARRANGEMENT EMPLOYING A SENSOR EGO A CURRENT TRANSFORMER (10) REMOTE FROM A MEASUREMENT DEVICE (15), THE SENSOR IS PROVIDED WITH A SIGNAL GENERATOR (20) FOR INJECTING A MONITOR SIGNAL INTO THE CONDUCTOR (17, 18) CONNECTING THE SENSOR TO THE MEASUREMENT DEVICE. THE MEASUREMENT DEVICE (15) IS PROVIDED WITH A SIGNAL DETECTOR (21) FOR MONITORING THE INPUT TO THE DEVICE FOR THE PRESENCE OF THE MONITOR SIGNAL. PREFERABLY, THE MONITOR SIGNAL IS AN AC SIGNAL AT A FREQUENCY CLOSE TO MAINS FREQUENCY.
