Abstract:
1. A branch circuit monitor including a current transformer, said branch circuit monitor comprising: (a) a memory storing a manufacturer's identity for each of a plurality of transformers and a plurality of correction factors, each correction factor useful for adjusting an output of at least one current transformer for a transformer induced error, said plurality of correction factors enabling adjustment of a respective output of each of said plurality of current transformers having an identity stored in said memory; and (b) a data processing unit executing an instruction enabling selection of one of said plurality of current transformers having an identity stored in said memory by specifying one of said manufacturer's identities stored in said memory and executing a second instruction applying at least one stored correction factor appropriate for said selected current transformer to an output of said current transformer included in said branch circuit monitor; (c) said data processing unit receiving an additional identity and storing said additional identity in said memory for an additional current transformer not included within any of said plurality of current transformers, and said data processing unit executing said instruction enabling selection of said additional identity for said additional current transformer stored in said memory by specifying one of said manufacturer's identities stored in said memory and executing another instruction applying at least one stored correction factor appropriate for said additional transformer to an output of said additional transformer included in said branch circuit monitor.
