Patent ID: 8004271

Claim:
A self contained kilowatt-hour meter, comprising: a) a meter housing having at least two openings for the passage of at least one electrical connection; b) a middle assembly comprising: at least one printed circuit board, at least two toroidal transformers, at least two openings for the passage of at least one electrical connection, such that each of said toroidal transformers is adjacent each opening for the passage of at least one electrical connection, such that said toroidal transformers are placed adjacent a load center main for generating a current signal proportional to that of said load center main, and at least one resistive divider for generating voltage signals which is directly proportional to said main voltage; and at least one integrated circuit capable of measuring energy in communication with the toroidal transformer and the at least one resistive divider to receive said current signals and voltage signals such that said signals are scaled, filtered, and sent to, and said resulting measured energy is sent to at least one display device; c) a meter cover having at least two openings for the passage of at least one electrical connection; and d) at least one securing means to secure said meter cover to said meter housing such that said middle assembly is contained inside said meter cover and said meter housing, and wherein each of said at least two openings for the passage of at least one electrical connection are substantially aligned each with other, and thereby forming said self contained kilowatt-hour meter.
