The metering techniques used were the Russ Track and handheld Fluke meters. In all, the model tested provided adequate buck voltage regulation. You can't always spot a well-designed voltage regulator from the outside. But our engineers did find real value when they looked inside this one. However, the packaging and construction of the device was not yet in a production mode and could not be evaluated.
More development is required.
The device will need to be efficiently designed, reduce the size and leave enough space between the meter and socket of no more than 8 inches otherwise the application of meter socket installation might be impracticable. We didn't test any prototype socket installation feature. Recommendations Voltage regulators for whole house use are new and have not been tested thoroughly. The regulator appears to have great potential to offer distribution engineering flexibility to lower the cost of voltage regulation. We tested only under limited conditions and more testing is needed to finalize any recommendation.
