Abstract :
This paper covers backgrounds of current zero measurement in investigations on interruption of high short circuit currents. After analyzing the complex network formed by the outer tube, resistance tube and potential lead of a coaxial shunt, typical LF and HF performance is described. Also attention is paid to construction details in connection with electromagnetic forces, accuracy, acceptable temperature rise and precautions against double grounding.
