Abstract

The measurement of small direct currents in presence of high AC currents on high voltage potential is a challenging task. Inductive current transducers (CT) are not able to measure DC and other non-conventional CTs are also not designed for DC. Therefore, DC measurements are done in transformer neutral points on ground potential. In this work, the state of the art on DC measurements in the high-voltage transmission grid is given, including the measurement in the transformer neutral point, the indirect measurement with the differential magnetometer method, and the indirect method of measuring a compensating current. In addition an optical current measurement system under development is presented.
