Abstract
A standard inductance box, relating to the fields of measurement or calibration, and relating in particular to a standard gauge for transferring an inductance parameter. The standard inductance box uses unary, binary and quinary, and comprises a physical inductance box section and a simulated inductance box section, said sections being respectively arranged in a metal box. Electrodes of the physical inductance box section and the simulated inductance box section are led out. The inductance range of the standard inductance box is 1 μH-500 H. The described means achieve an inductance range of 1 μH-500 H, expanding the inductance range in the prior art, and the application of a simulated inductance box. Using unary, binary and quinary standards reduces the size and weight of the physical inductance box section, facilitating transportation and use in the field.
