The paper describes the recent development of a system for calibration of electrical instruments with harmonics measurement capability, such as revenue meters and power analyzers, under nonsinusoidal test conditions at National Research Council (NRC) Canada. The improvements implemented with respect to an earlier NRC calibration system are aimed at increasing the calibration accuracy in a wider frequency range.

NRC Canada 在非正弦条件下校准电子仪器

该论文描述了加拿大国家研究委员会 (NRC) 在非正弦测试条件下对具有谐波测量能力的电气仪器（例如计价器和功率分析仪）进行校准的系统的最新发展。相对于较早的 NRC 校准系统实施的改进旨在提高更宽频率范围内的校准精度。
