Polyphase power distribution and monitoring apparatus
DCFirst Claim
1. A polyphase alternating current power distribution apparatus connectable to one or more electrical loads in an electrical equipment rack comprising, in combination:
- a vertical rack-mountable housing;
a polyphase power input disposed in the vertical rack-mountable housing;
a plurality of power outputs disposed on a face of the vertical rack-mountable housing, with at least one power output being in power supply communication with a first power phase provided by the polyphase power input and at least a second power output being in power supply communication with a second power phase provided by the polyphase power input; and
a display system disposed on the face of the vertical rack-mountable housing comprising;
a first display segment in power information determining communication with the first power phase; and
a second display segment in power information determining communication with the second power phase;
whereby the first display segment can report visible first power phase information while the second display segment reports visible second power phase information.

Abstract
A polyphase power distribution and monitoring apparatus having sets of outputs for each phase of power and monitors for each phase of power disposed in the housing. Each monitor provides a visible display of current for an associated phase of power and an audible alarm for each phase of power if the current exceeds a predetermined value or falls below a predetermined value. In three-phase wye power systems, the apparatus preferably includes a neutral line monitor, including a neutral line current display and audio alarm, for the neutral line of the wye power circuit. The apparatus preferably is lightweight, elongated, portable, and mountable to the side of an electronic equipment rack. It may also include additional power monitoring systems such as network power monitoring tools for remotely monitoring the apparatus.
