ABSTRACT:
A system and method for transmitting data from a utility meter, such as a power meter, is disclosed. A microprocessor housed inside the power meter obtains readings of various power indicia, stores the readings in memory, and determines an efficient means of formatting the data for transmission to a remote host computer for further processing and use. The data is selectively compressed to minimize the amount and size of data that needs to be transmitted. The microprocessor is mounted on a circuit board assembly within the power meter housing and interfaces between the meter board of the power meter and a transmitter. The transmitter communicates the formatted and potentially compressed data from the power meter to the remote host computer wirelessly or via hard-wired communication lines. The various power indicia include power usage or power quality information.
