ABSTRACT:
An electrical metering system includes an electrical meter which is free of current sensors and an external current sensor for producing an output signal related to electrical current conducted by a transmission line to an electrical load associated with the electrical meter such that the power consumption of the electrical load can be computed by the electrical meter. The current sensor generally can include an unbalanced bridge circuit for producing a scaled output signal related, according to a predetermined ratio to the electrical current conducted by the transmission line. The electrical meter generally includes a register, responsive to the output signal produced by the external current sensor, to tabulate load data related to the power consumption of the associated electrical load. By employing an external current sensor capable of providing relatively large current transformation ratios, the electrical meter need not include a current sensor and the design of the electrical metering system can be greatly simplified.
