CPC G01R 31/088 (2013.01) [G01R 31/085 (2013.01); G01R 31/086 (2013.01); H04B 3/542 (2013.01)] | 12 Claims |
1. A method for ensuring integrity of transmission-line voltage measurements in a digital-electricity power system comprising one or more transmitters, the method comprising:
with each transmitter, monitoring and controlling voltage of digital-electricity power transmission on a respective transmission line, wherein the digital-electricity power comprises energy packets; and
ensuring integrity of transmission-line voltage measurements in the presence of line-voltage disturbances during a sample period by using a bias circuit distinct from transmission-line capacitance to apply a negative or positive bias to the transmission line during the sample period; acquiring voltage measurements with the bias applied; determining a rate of voltage change with the bias applied; and interrupting the transmission of digital-electricity power over the transmission line when the rate of voltage change is outside of predetermined minimum and maximum values, including interrupting the transmission of digital-electricity power over the transmission line when the rate of voltage change is below the predetermined minimum due to excessive line capacitance.
