Four-terminal shunts are used as standards for current measurements up to 10 A, primarily to tie alternating-current measurements to direct-current measurements. The shunt is of the bifilar flat strip configuration, where self-inductance, skin effect, capacitance, dissipation factor, and eddy-current losses are considered. This allows the shunt to have calculable and predictable electrical properties, which is useful in a variety of electrical metrology applications. The authors provide assembly details of the shunt based on the mechanical drawings made available in the appendix. Practical issues of measuring 4-terminal shunts, with emphasis on dealing with common-mode potentials, are discussed. The thermal properties of the current shunt are presented, together with suggestions on reducing the power coefficient of resistance. This book will be of interest to electrical engineers, metrologists, and anyone interested in the design and construction of precision electrical measuring instruments.
