What are the definitions/formulas for the electrical quantities (Power, Current, Voltage, etc...) in the CM3000 (CM3), CM4000 (CM4), and PM800 (PM8)?

The PowerLogic meters use the definitions from IEC 61557-12 which are derived from IEEE 1459.
Annex A from IEC61557-12 has the definitions/formulas for all electrical parameters and Annex B from IEC61557-12 explains demand calculations.
