P1122 - Standard for Digital Recorders for Measurements in High-Voltage and High-Current Impulse Tests

Project Details

This standard is applicable to digital recorders and digital oscilloscopes used for measurements during tests with high-impulse voltages and high-impulse currents, as defined in IEEE Std 4-2013, IEEE Standard for High-Voltage Testing Techniques. It covers the measuring characteristics and calibrations required to meet the measuring accuracy specified in IEEE Std 4-2013 and IEEE Std C57.98-2011. The characteristics of general-purpose digital recorders are covered in IEEE Std 1057-2007. This standard a) Defines the terms specifically related to the digital recorders used for making high-voltage and high-current impulse measurements; b) Specifies the necessary performance characteristics for such digital recorders to ensure their compliance with the requirements for high-voltage and high-current impulse tests; c) Describes the tests and procedures that are necessary to show that these performance characteristics are within the specified limits.

Existing Standards	Superseded IEEE 4-1995 - IEEE Standard Techniques for High-Voltage Testing This standard establishes standard methods to measure high-voltage and basic testing techniques, so far as they are generally applicable, to all types of apparatus for alternating voltages, direct voltages, lightning impulse voltags, switching impulse voltages, and impulse currents. This revision implements many new procedures to improve accuracy, provide greater flexibility, and address practical problems associated with high-voltage measurements.
	Superseded IEEE 4a-2001 - Amendment to IEEE Standard Techniques for High-Voltage Testing This amendment sets forth a number of clarifications and corrections to IEEE Standard Techniques for High-Voltage Testing.
	Active IEEE 1122-1998 - IEEE Standard for Digital Recorders for Measurements in High-Voltage Impulse Tests 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.
	Active IEEE 4-2013 - IEEE Standard for High-Voltage Testing Techniques Standard methods and basic techniques for high-voltage testing applicable to all types of apparatus for alternating voltages, direct voltages, lightning impulse voltages, switching impulse voltages, and impulse currents are established in this standard. Sections that deal with alternating voltage, direct voltage, and impulse testing are combined in this revision to organize the technical content for ease of use. In addition, the concept of measurement uncertainty in evaluation of high-voltage and high-current tests is introduced in this version.
