电容器的损耗因数关系到电容器的质量，也是新型介电材料、绝缘材料的生产和特性研究的重要技术指标。并且是绝对相位、电功率和电能测量的溯源依据。中国计量科学研究院电容器损耗因数基准从1980年开始研制，于1985年通过国家鉴定，1988年2月经原国家计量局批准为国家基准。电 Capacitance loss factor related to the quality of capacitors, but also the new dielectric materials, insulation materials, production and characteristics of the important technical indicators. And is the absolute phase, electric power and energy measurement traceable basis. China Institute of Metrology capacitor loss factor benchmark developed from 1980, in 1985 through the national identification, in February 1988 by the former National Bureau of Metrology approved as the national benchmark.
