Construction of Maxwell-Wien Bridge at SASO-NMCC

An inductance calibration system for standard inductors based on a Maxwell-Wien bridge has been constructed at Saudi Standards Metrology and Quality Organization, National Measurement and Calibration Center (SASO NMCC). Expanded measurement uncertainty has been estimated to be less than $\pmb{20\ \mu \text{H}/\text{H}}$ for 100 mH inductance at 1 kHz. A bilateral comparison between SASO NMCC and TUBITAK UME has been performed in order to evaluate the performance of the calibration system.
