Power check meter

Year	Description
1997	Invention patented by Tom Durston on March 3rd, 1997. Abstract: A power measurement system calculates the power flow within a wire to a customer and transmits an indication of the power flow to a remotely located operator. The measurement system includes both a current transformer that senses current within the wire and generates a first output signal and a voltage input that senses voltage within the wire and generates a second output signal. A measurement device receives both the first and second output signals and in response generates a third signal representative of the power flow within the wire. The measurement device includes both a speech encoding circuit that receives the third signal and in response generates a voice signal, and a transmitter that receives the voice signal and transmits the voice signal to the remotely located operator.
