Method for Validating Voltage Measurements in a Digital-Electricity Transmission System

A digital-electricity power system, comprising:

• at least a pair of transmission lines;
• at least one transmitter in electrical communication with a transmission end of the transmission lines, wherein the transmitter is configured to transmit digital-electricity power over the transmission lines and is further configured to monitor and control voltage on respective transmission lines;
• and
• at least one receiver in electrical communication with a receiving end of the transmission lines, wherein the transmitter is configured to interact with the receiver;
• a controller in the transmitter or in the receiver, wherein the controller includes a processor and a computer-readable medium in communication with the process and non-transitorially storing software code including instructions for:
• a) using the at least one transmitter to acquire a series of transmission-line voltage measurements during a sample period when a transmitter-disconnect device is in a non-conducting state;
• b) using the receiver to acquire a series of receiver voltage measurements during the same sample period;
• c) transferring the receiver voltage measurements to the transmitter;
• d) calculating when AC components of the transmission-line voltage measurements and AC components of the receiver voltage measurements have diminished to a point at which the primary change in the transmission-line voltage measurements is due to DC decay and storing a first voltage measurement acquired at that point;
• e) determining the voltage values at the transmitter and receiver at a point after the AC components have diminished to the point at which the primary change in the voltage measurements is due to DC decay in both the transmission-line and receiver voltage measurements;
• and
• f) placing the transmitter-disconnect device in a non-conducting state if the difference between the values is greater than a predetermined maximum value, wherein the transmission-line voltage measurements cannot be validated.
