IEC 61000-4-18 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, concerning:
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 IEC 61000-4-18 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. 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 IEC 61000-4-18 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. It has the status of a basic EMC publication in accordance with IEC Guide 107.
