          Superseded by IEEE Std C57.13-2008. 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. Interpretations are available at http://standards.ieee.org/reading/ieee/interp/C57.13-1993.html<br />\n

          Revision Standard - Superseded.<br />\n
          Superseded by IEEE Std C57.13-2008. 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. Interpretations are available at http://standards.ieee.org/reading/ieee/interp/C57.13-1993.html<br />\n
