电容器行业需要快速准确地表征元件等效串联电阻（ESR）和电容(C)。在制造环境中，测量必须非常快速，可重复和高质量，用于过程控制，数据收集和监控，以及在组件SKU标签上打印。最快的表征测试是使用脉冲技术进行的，这些技术必须提供对真实参数值的准确评估。在这项工作中，开发了一种量热计方法来证实ORNL最近开发的电子ESR表征方法获得的ESR值。量热计测量是非常缓慢的，繁琐的，并且容易出错，如果室入口空气没有适当调节。研究发现，用于安装功率环大电流电容器的临时共面母线板在ESR结果中引入了电子测量技术所没有的频率依赖性。量热计方法可以很好地在额定电流、频率和波形的实际应用条件下进行参数表征。
The capacitor industry requires fast and accurate characterization of component equivalent series resistance (ESR) and capacitance (C). In a manufacturing setting the measurements must be very fast, repeatable and high quality for use in process control, data collection and monitoring, plus for printing on the component SKU label. The fastest characterization testing is done electronically using pulse techniques and these must provide accurate assessment of the true parameter values. In this work a calorimeter method was developed to corroborate ESR values obtained using a recently developed electronic ESR characterization method at ORNL. Calorimeter measurements are very slow, tedious and subject to error if chamber inlet air is not properly conditioned. It was found that the provisional coplanar bus plate used for mounting a power ring high current capacitor introduced frequency dependence in ESR results that electronic measurement techniques did not incur. The calorimeter method lends itself well to parameter characterization under real world application conditions at rated current, frequency and wave shape.
