GB/T 17626.3-2023

Electromagnetic   compatibility—Testing and measurement techniques—Part 3：Radiated,   radio-frequency, electromagnetic   field immunity test

It is applicable to the   immunity requirements of electrical and electronic equipment to radiated   electromagnetic energy. It establishes test levels and the required test   procedures.
  The object of this document is to establish a common reference for evaluating   the immunity of electrical and electronic equipment when subjected to   radiated, radio-frequency electromagnetic fields. The test method documented   in this part of EMC standard describes a consistent method to assess the   immunity of an equipment or system against RF electromagnetic fields from RF   sources not in close proximity to the EUT.
  Particular considerations are devoted to the protection against   radio-frequency emissions from digital radiotelephones and other RF emitting   devices.
  This standard is an independent test method. It is not possible to use other   test methods as substitutes for claiming compliance with this document.

Electromagnetic   compatibility—Testing and measurement techniques—Part 30: Power quality   measurement methods

This standarddefines   the methods for measurement and interpretation of results for power quality   parameters in a.c. power supply systems with a declared fundamental frequency   of 50 Hz or 60 Hz.
  Measurement methods are described for each relevant parameter in terms that   give reliable and repeatable results, regardless of the method’s   implementation. This standard addresses measurement methods for in-situ   measurements.
  Measurement of parameters covered by this standard is limited to conducted   phenomena in power systems. The power quality parameters considered in this   standard are power frequency, magnitude of the supply voltage, flicker,   supply voltage dips and swells, voltage interruptions, transient voltages,   supply voltage unbalance, voltage harmonics and interharmonics, mains   signalling on the supply voltage, rapid voltage changes, and current   measurements. Emissions in the 2 kHz to 150 kHz range are considered in Annex   C (informative), and over- and underdeviations are considered in Annex D   (informative). Depending on the purpose of the measurement, all or a subset   of the phenomena on this list may be measured.

GB/T 17626.39-2023

Electromagnetic   compatibility—Testing and measurement techniques—Part 39：Radiated fields in close   proximity immunity test

This standard specifies   immunity requirements for electrical and electronic equipment when it is   exposed to radiated electromagnetic energy from RF transmitters used in close   proximity. It establishes test levels and the required test procedures. The   applicable frequency range is 9 kHz to 6 GHz. Fixed-installation equipment   being exposed to portable transmitting devices, mobile equipment exposed to   fixed transmitting devices and mobile equipment exposed to other mobile   transmitting devices are considered.
  The object of this standard is to establish a common reference for evaluating   the immunity requirements of electrical and electronic equipment that is   exposed to radiated, RF electromagnetic fields from sources at close   distances. It is understood that this part of GB/T 17626 does not replace   general immunity requirements of electrical and electronic equipment to   radiated electromagnetic energy as given in GB/T 17626.3 and other parts of   GB/T 17626 and that it is only applicable if an equipment or system is   exposed to disturbance sources in close proximity.

Electromagnetic   compatibility—General—Part 7: Power factor in single-phase systems under   non-sinusoidal conditions

This standard  provides definitions of various electrical   power quantities and the relationship between them under non-sinusoidal   conditions, in order to give clear information on both components in the   power factor: the fundamental power factor, which is due to the phase   difference between the voltage and current at the fundamental frequency, and   the non-fundamental power factor, which is related to the distortion of the   voltage and/or current. This Technical Report is applicable only to single   phase systems.
  It provides definitions for the three following cases:
  • the general case where the voltage and current are both distorted (Clause   5),
  • the case where the voltage is assumed to be sinusoidal and the current is   only distorted with harmonic components (Clause 6),
  • the particular case where the voltage and current are both sinusoidal   (Annex A).
  Annex B gives information on the fundamental active factor, which is used to   describe the behavior of a piece of equipment as a load or a generator.
