Abstract: The integrity of transmission-line voltage measurements in a digital-electricity power system in the presence of line-voltage disturbances during a sample period is ensured via detection or prevention by (a) acquiring at least three measurements of transmission-line voltage, performing numerical analysis on the measurements to produce a polynomial function, and estimating accuracy of the polynomial function based on magnitude of variance of the individual measurements; (b) applying a negative or positive bias to the transmission line during the sample period and acquiring voltage measurements to determine a rate of voltage change with the bias applied; (c) shifting a start time of a first sample period on a first transmission line in reference to a second sample period on a second transmission line to reduce overlap of sample periods across both transmission lines; and/or (d) synchronizing start times of respective sample periods on first and second transmission lines.

Abstract: A digital power distribution system includes a source sensor configured to provide feedback that includes a signal indicative of voltage across the source terminals; a source controller configured to receive the feedback from the source sensor and to generate a control signal that opens a source disconnect switch between the power source and the source terminals; a non-linear load configured such that the electrical current it draws from the load terminals drops by at least an order of magnitude below a non-zero voltage threshold; reduced capacitance for storing charge and discharging that charge during the sample period, wherein the reduced capacitance is at a level for providing this low level of electrical current drawn by the non-linear load. The system can be configured without a disconnect switch between the load terminals and the non-linear load to thereby maintain the non-linear load in electrical contact with the load terminals.

Abstract: A digital power distribution system includes a source sensor configured to provide feedback that includes a signal indicative of voltage across the source terminals; a source controller configured to receive the feedback from the source sensor and to generate a control signal that substantially increases or decreases impedance between the power source and the source terminals; a non-linear load configured such that the electrical current it draws from the load terminals drops by at least an order of magnitude below a non-zero voltage threshold; reduced capacitance on the load side for storing charge and discharging that charge during the sample period, wherein the reduced capacitance is reduced to a level for providing the at-least-an-order-of-magnitude-lower electrical current drawn by the non-linear load below the voltage threshold; and a source disconnect device responsive to the control signal from the source controller.
