1. A method of automatically configuring a power monitoring system for alarm aggregation, comprising: storing a representation of a hierarchy in a memory, said hierarchy being indicative of how a plurality of monitoring devices are logically linked to one another in said power monitoring system; receiving, from at least two of said monitoring devices, respective alarm data indicative of an electrical characteristic being exceeded, said electrical characteristic being monitored by respective ones of said at least two monitoring devices; determining whether said alarm data from each of said at least two monitoring devices were triggered within the same time period and whether said at least two monitoring devices are linked together in said hierarchy; responsive to said alarm data from each of said at least two monitoring devices being triggered within a predetermined time period and responsive to said at least two monitoring devices being linked together in said hierarchy, automatically aggregating said alarm data from said at least two monitoring devices to form an aggregated alarm; storing aggregated alarm data indicative of said aggregated alarm; and communicating a representation of said aggregated alarm.
