Abstract
Present work can be used to calibrate inductance standards by utilizing the error evaluated at the same nominal value of reactance of a capacitance standard. Inductance can be determined in terms of capacitance standard by direct measurement of capacitive reactance on the LCR meter. The conventional Maxwell–Wien bridge is currently used at CSIR-NPL to determine traceability to the inductance standard through capacitance and two resistance standards. However, proposed technique defines inductance in terms of one capacitance only. Measurement results of 100 mH inductors at 1 kHz are evaluated and validated with the inductor's previously assigned values with Maxwell–Wien bridge. Preliminary results obtained from both techniques were found within 50 ppm; hence this technique can be used as an alternative to Maxwell–Wien bridge.
