ABSTRACT:
An anti-energy diversion system for mounting underneath the cover of a standard electric utility meter in order to sense common meter tampering events and indicate the occurrence of such events. A non-battery energy storage circuit extracts energy from the AC power line available in the meter to power the system even during power outages. A flashbulb associated with a heat sensitive indelible indicator is coupled to the energy storage circuit when any one of several tamper event sensor switches are closed. When a tamper event is sensed, a brilliant flash of light is discharged and the appearance of the indelible indicator is transformed.
