Calibration system for a power meter
First Claim
1. A method for calibrating a power meter comprising:
- (a) mechanically detachably engaging a first power meter with a second power meter in a manner such that said second power meter is completely mechanically detachable from said first power meter, and detachably electrically engaging said first power meter with said second power meter in a manner such that said second power meter is completely electrically detachable from said first power meter, a first housing substantially enclosing said first power meter, a second housing substantially enclosing said second power meter, wherein said first housing is completely mechanically and electrically separate from said second housing when said first power meter is said completely mechanically detached and said completely electrically detached from said second power meter, said mechanically detachably engaging includes said first housing being in direct mechanical contact with said second housing such that a portion of said first housing comes into direct contact with said second housing, said detachably electrically engaging includes an electrical connection between said first power meter and said second power meter where said electrical connection is configured in a manner that is not capable of being electrically interconnected to another power meter mechanically detachably engaged with said first housing;
(b) receiving by said first power meter a first current input signal representative of a current level in a first conductor to a load;
(c) receiving by said first power meter a first voltage input signal representative of a voltage level in said first conductor;
(d) determining by said first power meter a first power level based upon said first current input signal and said first voltage input signal;
(e) receiving by said second power meter a second current input signal representative of said current level in said first conductor to said load from said first power meter;
(f) receiving by said second power meter a second voltage input signal representative of said voltage level in said first conductor to said load from said first power meter;
(g) determining by said second power meter a second power level based upon said second current input signal and said second voltage input signal.

Abstract
A system for calibrating a power meter may include mechanically detachably electrically engaging a first power meter with a second power meter. The first power meter may receive a first current input signal representative of a current level in a first conductor to a load and receive a first voltage input signal representative of a voltage level in the first conductor, and determine a first power level based upon the first current input signal and the first voltage input signal. A second power meter may receive a second current input signal representative of the current level in the first conductor to the load from the first power meter, receive a second voltage input signal representative of the voltage level in the first conductor to the load from the first power meter, and determine a second power level based upon the second current input signal and the second voltage input signal.
