Abstract
The disclosed technology comprises a device and a method for accurately determining the amount of electrical energy utilized in a circuit with a quarter-cycle transformer and transducers operating off quarter-cycle power. The method allows for a primary power meter associated with an entity which provides a power source to remain in operation, without modification, and for a second power meter to be utilized which accurately measures consumption of quarter-cycle power usage. An adjustment to an invoice can then be made, based on the difference.
