This part of IEC 61000-4 relates to the immunity requirements and test methods for electrical
and electronic equipment, under operational conditions, with regard to:
a) repetitive damped oscillatory waves occurring mainly in power, control and signal cables
installed in high voltage and medium voltage (HV/MV) substations;
b) repetitive damped oscillatory waves occurring mainly in power, control and signal cables
installed in gas insulated substations (GIS) and in some cases also air insulated
substations (AIS) or in any installation due to HEMP phenomena.
The object of this basic standard is to establish the immunity requirements and a common
reference for evaluating in a laboratory the performance of electrical and electronic equipment
intended for residential, commercial and industrial applications, as well as of equipment
intended for power stations and substations, as applicable.
NOTE As described in IEC guide 107, this is a basic EMC publication for use by product committees of the IEC.
As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity
test standard should be applied or not, and if applied, they are responsible for determining the appropriate test
levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees
in the evaluation of the value of particular immunity tests for their products.
The purpose of this standard is to define:
– test voltage and current waveforms;
– ranges of test levels;
– test equipment;
– test setup;
– test procedure.
The object of this standard is to establish a common reference for evaluating the immunity of
electrical and electronic equipment when subjected to damped oscillatory waves. The test
method documented in this part of IEC 61000 describes a consistent method to assess the
immunity of an equipment or system against a defined phenomenon.t_agzhtt
