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.

使用商用LCR表通过电容确定电感

通过利用在电容标准的电抗的相同标称值下评估的误差,当前的工作可用于校准电感标准。可以根据电容标准,通过在LCR表上直接测量电容电抗来确定电感。CSIR-NPL当前使用常规的麦克斯韦-威恩电桥来确定通过电容和两个电阻标准可追溯到电感标准的情况。然而,提出的技术仅根据一个电容来定义电感。使用麦克斯韦-维恩电桥的电感器先前分配的值评估并验证了100 mH电感器在1 kHz下的测量结果。从这两种技术获得的初步结果均在50 ppm以内。因此,该技术可以用作麦克斯韦-维恩桥的替代方案。
