【英文标准名称】: Requirements for instrument transformers 【原文标准名称】: 仪表用变压器的要求 【标准号】: IEEE C 57.13-1993 【标准状态】: 作废 【国别】: 美国 【发布日期】: 1993 【实施或试行日期】: 【发布单位】: 美国电气电子工程师学会(IEEE)【起草单位】: IEEE【标准类型】: ()【标准水平】: ()【中文主题词】: 规范(批准);电气工程;仪表用变压器;变压器;电流互感器;交流电流【英文主题词】: Alternating current;Current transformers;Electrical engineering;Instrument transformers;Specification (approval);Transformers【摘要】: Electrical, dimensional, and mechanical characteristics are covered, taking into consideration certain safety features, for current and inductively coupled voltage transformers of types generally used in the measurement of electricity and the control of equipment associated with the generation, transmission, and distribution of alternating current. The aim is to provide a basis for performance, interchangeability, and safety of equipment covered, and to assist in the proper selection of such equipment. Accuracy classes for metering service are provided. The test code covers measurement and calculation of ratio and phase angle, demagnetization, impedance and excitation measurements, polarity determination, resistance measurements, short-time characteristics, temperature-rise tests, dielectric tests, and measurement of open-circuit voltage of current transformers.【中国标准分类号】: L17【国际标准分类号】: 17_220_20【页数】: 85P;A4【正文语种】: 英语
