• Rack PDU: Rack Power Distribution Unit - This represents the input power and multiple outputs to load

segments.

• Load Segment: This represents each of the outputs of the PDU that can be monitored. HP PDU

Management Module discovers up to the Load Segment level of the power topology.

• Outlet Bar: This represents the division of the load segment into multiple outlets.

• Outlet: A circuit with one input and one output that can be monitored.

• Load: The power consumer connected to the outlet. The load can be a system, enclosure, or

undiscoverable system.

Power Calculation

Assumptions

Insight Control power management assumes the following for calculating power:

• 1-phase is treated as 1-phase NA/JPN (line-to-line). You cannot change this to INT 1-phase.

• The load factor is 1. So, VA and Watts units are the same.

• All loads are balanced.

Power calculation

The power calculation in general can be categorized as:

• Power delivery device voltage discovery

• Power delivery device total capacity calculations

• Converting watts to amperes

• Converting amperes to watts

Power delivery device voltage discovery

If you know the power hierarchy of a power delivery device, the missing voltages can be found during

discovery phase. Insight Control power management finds the missing voltages for 1-phase, 3-phase Delta,

and 3-phase Wye PDUs made up of 1-phase sub-circuits assuming the usage of the device is balanced.

If you know the input (line) voltage of the device, the output (phase) voltage of each sub-circuit is defined

as:

1-phase - The input (line) voltage

3-phase Delta - The input (line) voltage

3-phase Wye - The input (line) voltage / sqrt(3)

If you know the output (phase) voltage for the sub-circuits, the input (line) voltage of the device is defined

as:

1-phase - The output (phase) voltage

3-phase Delta - The output (phase) voltage

3-phase Wye - The output (phase) voltage * sqrt(3)

Power delivery device total capacity calculations

If you know the line current (lineCurrent), line voltage (lineVoltage), and type of phase for the device, the

total capacity of a power delivery device can be calculated using the following formulas:

For 3-phase Wye:

phaseVoltage = lineVoltage / sqrt(3)

phaseAmps = lineCurrent

phaseWatts = phaseVoltage * phaseAmps

TotalCapacity = 3 * phaseWatts

For 3-phase Delta:

phaseVoltage = lineVoltage

phaseAmps = lineCurrent / sqrt(3)
