Abstract :
Centro Español de Metrología (CEM) has developed a new ac-dc current standard to improve our measurement capabilities and extend the measurement range to 100 A and 100 kHz. The new standard is based on a step-up procedure using the combination of specially designed shunts and planar multijunction thermal converters. The new CEM ac-dc standard, the validation method, the uncertainty estimation, and the results are described.
