IEEE 1122-1998

This standard is applicable to digital recorders and digital oscilloscopes used for measurements during tests with high-impulse voltages and high-impulse currents. It covers the measuring characteristics and calibrations required to meet the measuring accuracy specified in IEEE Std 4-1995 and IEEE Std C57.98-1993 To simplify the existing standard and to bring it into alignment with the new proposals in the revision of ANSI/IEEE Std. 4 Revision Standard - Inactive-Reserved. Reaffirmed September 2007. Instructions are given for conducting and reporting the more generally applicable and acceptable tests to determine the performance characteristics of polyphase induction motors and generators. Electrical measurements, performance testing, temperature tests, and miscellaneous tests are covered.
