| Summary | This standard applies to electrical equipment, components and systems at a frequency of 400 H: and below the AC voltage or DC voltage test trials generated when partial discharge measurements. This standard: Defining the terms of partial discharges, define the most relevant test parameters, specifies the use of the test circuit and measuring circuit, provides universal analog and digital side volume method, given calibration methods and the calibration of the instrument requirements, given test procedures, gives distinction partial discharge and external interference criteria. This standard terms can be used to power equipment woo drafting special technical conditions for partial discharge measurements �� This standard mainly involves impulse type (short duration) electrical partial discharge measurements, but also gives a partial discharge location is mainly used for non-electrical measuring method (see Appendix F). Specific characteristics of electrical equipment by partial discharge diagnosis of digital signal processing (see Appendix E) and is mainly used for partial discharge location of non-electrical measuring method (see Appendix F) is completed. This standard describes the AC voltage test electrical partial discharge measurement methods, but also referred to the DC voltage test when special problems (see Chapter 11). This standard terminology, definitions, and procedures for the basic test circuit are also generally applicable to other frequency tests conducted, but may seek a special test playing methods and measuring system characteristics, these requirements are not considered in this standard. Appendix A gives a standard for calibration of the performance test requirements. |
