1. A sensor system for use in a high voltage direct current network, the sensor system comprising
a plurality of sensor devices, each sensor device configured to obtain a respective sensor measurement, wherein the plurality of sensor devices are configured to generate a serial data unit for transmission to a recipient system, the serial data unit comprising a serial sequence of bits configured to include a plurality of sensor measurements, the serial sequence of bits further configured to include a plurality of validity indicators, each validity indicator being in between two respective sensor measurements of the plurality of sensor measurements in the serial sequence of bits and configured to provide an individual validity status of a respective one of the two respective sensor measurements;
a sensor management unit configured to evaluate said each validity indicator from the serial data unit to detect that the serial sequence of bits comprises a first validity indicator labeling a valid sensor measurement for a first sensor measurement adjacent to the first validity indicator in the serial sequence of bits and a second validity indicator labeling an invalid sensor measurement for a second sensor measurement adjacent to the second validity indicator in the serial sequence of bits
the sensor management unit further configured to generate a modified serial data unit based on the serial data unit subsequent to the sensor management unit evaluating said each validity indicator, and to determine, based on the second validity indicator, that the second sensor measurement is invalid, wherein the modified serial data unit is configured to include the valid sensor measurement from the serial data unit and an error indicator that identifies the second sensor measurement from the serial data unit as invalid and to include the error indicator that identifies the second sensor measurement from the serial data unit as invalid; and
the sensor management unit further configured to transmit the modified serial data unit to the recipient system; and
wherein the sensor management unit is further configured to transmit the serial data unit to the recipient system in response to the sensor management unit determining that none of the plurality of sensor measurements are invalid.
