Abstract
The disclosure relates to a meter for monitoring usage of power provided by a power transmission system to a site and a related method. The meter comprises: a meter module connected to a power feed associated with the transmission system to provide readings relating to the power; a connection to a household AC power supply providing power to the meter; a rectifier circuit connected to the AC power to generate a DC power signal; a voltage detection circuit to detect a low voltage condition where an output from the rectifier circuit drops below an operational threshold for the meter and to generate a low voltage signal upon detection of same; and a message generation module for receiving the low voltage signal and for generating a power loss message for transmission carried on a message carrier having on a carrier having frequency between approximately 2 MHz and 30 MHz.
