Abstract: A power monitoring and loss prevention system includes actuators installed in lower level components of a primary power system, such as tap boxes of a power busway for an aisle of a data center. The power monitoring and loss prevention system redirects high frequency sampled power flow data to one or more computing devices that determine if power flows in the primary power system are at threshold levels that are likely to cause higher-level circuit breakers of the primary power system to be tripped. If so, the power monitoring and loss prevention causes one or more of the actuators to divert discrete lower level loads that are receiving power from the primary power system to instead receive power from a reserve power system such that power flows in the primary power system that may cause the higher level breakers of the primary power system to trip are avoided.
