Inductance measurements is important for all branches of technology related to the application of electricity: energy and electronics, radio and television, transport and communication, and scientific research. Electromechanical devices and electronic components can be characterized using impedance measurements to identify the parameters of their equivalent electrical model. New inductance measurement methods are being developed in specific fields of activity. Manufacturers of standards and measuring instruments of inductance develop special handbooks outlining various methods of inductance measurement. The State Primary Standard of Ukraine for inductance and loss angle tangent reproduces and transmits a unit of inductance in the range from 1∙10-6 H to 10 H at a frequency of 1 kHz. It is keeping in the SE “Ukrmetrteststandard” and participated in several comparisons of national standards within the framework of the activities of regional metrological organizations. The calibration and measurement capabilities of inductance measurement of national laboratories of different countries were studied to analyze and compare the capabilities of the national standard with the standards of other countries. Long-term instability studies of inductance measures of 1 mH, 10 mH and 100 mH, which are part of the national standard unit of inductance, have been conducted. The research period covered from 2009 to 2022. It was established that the drift lines of the specified inductance measures can be described using linear approximations. The rationale for choosing inductance measures of 10 mH and 100 mH for their use as transmission standards in the calibration of standards, which were organized and conducted by SE “Ukrmetrteststandard” as their pilot laboratory, is given.

Inductance measurements are important in many fields, especially in electronics, electrical engineering, radio engineering, and other areas. The inductance is often an important parameter in a wide range of applications such as radio transmitters, power circuits, magnetic resonance pulsed sources, etc. The accuracy of the inductance affects the quality of products, especially in devices where inductors are used, such as filters, transformers, inverters, etc. High-precision inductance measurements are used for the product quality control to ensure that manufactured devices meet established specifications and standards. Drift is an undesirable property of all measuring instruments and measurement standards during their life cycle. The analysis of the instrumental drift of measurement standards is of great importance in metrology. Reliable drift accounting plays an important role in maintaining measurement accuracy. For electrical measurement standards, the long-term drift is predictable. The drift types and main methods of its estimation for measurement standards between their calibrations were analysed. The drift uncertainty can be evaluated from the history of successive calibrations, and in the absence of such history, the order of magnitude of the calibration uncertainty can be estimated. The results of the estimation of the long-term drift of the inductance measurement standards for high-precision calibration of measuring instruments and measurement standards by two methods, polynomial regression curves and Exponentially Weighted Moving Average (EWMA) schemes, are given. The EWMA schemes reduce the lag inherent in traditional moving averages by giving more weight to recent observations. It is shown that the use of the EWMA schemes compared to the regression analysis shows greater sensitivity to the drift changes in the last years of observations. This allows the laboratory to take this factor into account when calibrating measuring instruments and measurement standards.
