Power Calculations – Supply Fan

Objective/Method/Outcome

Objective: Calculates the power demand of supply fan.

Method: The Actual Runtime demand is calculated by using the equipment Amps, the Voltage Rating, the Voltage Phase Conversion, and the Power Factor. This is used to determine the hourly consumption.

Outcome: This rule runs Power calculation but triggers no insight.

Description

Calculates power demand and consumption from amperage trends and voltage rating. This rule is part of the CopperTree Standard rule-set.
