Electromagnetic compatibility test and measurement technology

Damping oscillatory wave immunity test

1 Scope

This part of GB/T 17626 relates to the immunity requirements and test methods of electrical and electronic equipment under operating conditions, which includes.

a) Repeated resistance in power cables, control cables and signal cables installed primarily in high voltage and medium voltage (HV/MV) substations

Nepalese oscillations.

b) Mainly in air-insulated substations (GIS) and in some cases air-insulated substations (AIS) or due to high-altitude electromagnetic pulses

(HEMP) under any of the facilities of the power cable, control cables and signal cables appear in the repeated damping oscillations.

The purpose of this section is to establish immunity requirements in the laboratory for evaluating the performance of residential, commercial and industrial electrical and electronic equipment

And common reference, when applicable, can also be used for power plants and substation equipment.

Note. This part is the basic standard for electromagnetic compatibility for use by the product committee, as specified in IEC Guide 107. IEC Guide 107 also states that the Product Committee is negative

To determine whether to apply this immunity test standard, if used, should also be responsible for determining the appropriate test level and performance criteria. National Electromagnetic Compatibility Standard

The Technical Committee and its subcommittee are willing to cooperate with the Product Committee to assess the specific immunity requirements of their products.

The purpose of this section is to provide that.

--- test voltage and current waveform;

--- test level range;

--- test equipment;

--- test arrangement;

--- test procedure.

The purpose of this section is to establish a common criterion for evaluating the immunity of electrical and electronic equipment when subjected to damped oscillations. This part

The specified test method describes a method of determining the consistency of the device or system for the defined electromagnetic interference.
