Abstract

Disclosed is a Power Distribution Units (PDUs) that assists the customer/user in determining the most efficient method for PDU outlet utilization. The PDU measures the current per outlet and voltage drops at various points along the distribution path and then, based on this data, reports to the user an alternate load install order and the anticipated power and/or operating cost savings realized after the change.

PDU Efficiency Based Outlet Recommendations

When plugging loads into Power Distribution Units (PDUs), customers often follow a predetermined outlet install order. This install order is typically based on the number of phases and the circuit breaker/outlet connection only. For example, outlets on a single phase PDU may be installed in numerical order. Outlets on a multi-phase PDU may be both sequentially installed on the phases and numerically installed. Internal power losses to the PDU are not considered. A solution is needed to assist the customer in determining a more efficient PDU outlet utilization to reduce the PDU's internal power losses and overall operating costs.

One current patent to be aware of is US8212395, Systems and Methods for Optimizing Power Loads in a Power Distribution Unit. This patent discusses determining the preferential install order for future loads based on balancing three-phase power and circuit breaker utilization. It does not use internal PDU power losses as a factor and does not recommend optimization of loads currently plugged into the PDU.

The proposed solution involves a PDU with the capability of measuring the current per outlet and voltage drops at various points along the distribution path. The PDU takes this data and calculates the power loss associated with each outlet. Based on this data, the PDU reports to the user an alternate load install order and the anticipated power and/or operating cost savings realized after the c...
