POWER DISTRIBUTION, MANAGEMENT, AND MONITORING SYSTEMS AND METHODS
First Claim
1. A power distribution unit comprising:
- a power distribution unit housing disposable in an electrical equipment rack of the type in which a plurality of electrical components are removably mountable;
at least one power input penetrating the housing;
a plurality of power outputs disposed in the housing, each in electrical communication with said at least one power input, and each connectable to an electrical load;
a sensor system, comprising;
at least one voltage sensor disposed in said housing; and
a plurality of current sensors disposed in said housing, each in electrical communication with an associated one of said plurality of power outputs to sense current therethrough; and
a power monitoring section in electrical communication with said sensor system and responsive to signals provided by said sensor system to calculate an amount of energy consumed by each connected load.

Abstract
Managing electrical power usage in a power distribution system. Power usage data indicative of electrical current flow through electrical outlets in the system are collected and displayed for a user. The user may select an outlet and issue a command to control current flow through that outlet. Environmental data may also be collected and displayed. Outlets in different Cabinet Power Distribution Units (CDUs) in different locations may be clustered for reporting and control. A database structure provides a “system” table for data descriptive of the system, a “tower” table for data descriptive of outlets and other elements in the system, an “infeed” table for data descriptive of input electrical power, and an “outlet” table for data descriptive of electrical power flowing through the outlets.
