Provisional Patent Application Filed

Description:

Electric transformers generally increase and decrease the voltage of the transmitted electricity appropriately to optimally transmit electricity with minimal power losses. They are used numerously by the utility industry for the transmission of electricity. However, in their present state, the regular transformers perform only the job of voltage escalation or reduction. They do not allow for the collection of electric data at the respective transformer’s location in the grid, nor do they communicate with the grid in any way. With the arrival of the smart grid and smart electric devices, a more elegant solution to the regular transformer is required.

The subject technology involves the design of a Solid State Smart Transformer that deftly combines a Solid State Transformer (SST) with a Phasor Measurement Unit (PMU). The technology upgrades the regular, bulky transformer into a more elegant and smaller (thereby cost-effective) smart device that provides both data input and control input regarding the electric power system.
