EVALUATION OF THE LONG TERM STABILITY OF INDUCTORS USING STANDARD ERROR OF ESTIMATE

• Abstract:

  The aim of this paper is to present a new method used to calculate the long term stability and drift of a group of standard inductors of the Laboratory of Capacitance and Inductance (Lacin), of the National Institute of Metrology, Normalization and Industrial Quality (Inmetro).
  Using the concepts of time series and standard error of estimate, we developed an automated system with the objective of determining the drift (tendency), the long term stability and to forecast future values, what constitutes a powerful tool in the control and in the conservation of measurement standards.
