A circuit monitor monitors one or more metered values in an electrical circuit, and includes a system for selecting alarm setpoints based upon learned characteristics of normal operation of metered values. The circuit monitor includes a controller and a memory. The memory includes a test register of alarms selected to be part of a learning process. The controller includes summaries and characterizes the one or more metered values as histogram formatted data corresponding to metered values identified by a test register of alarms selected to be part of a learning process. The controller stores the histogram formatted data in the memory and organizes the stored data into a plurality of memory locations, each covering a fixed range of time duration. The controller selects setpoints which produce a minimum product of metered value multiplied by time duration for Over Alarms or a maximum product of metered value multiplied by time duration for Under Alarms.
A circuit monitor for monitoring one or more metered values in an electrical circuit, said circuit monitor including a system for selecting alarm setpoints based upon learned characteristics of normal operation of metered values, said circuit monitor comprising:
A method of automated alarm setpoint learning in an electrical meter, said method comprising:
A system for setting alarm points for metered values, said system comprising:
