This part of GB/T 17626 involves the immunity requirements and test methods for electrical and electronic equipment under operating conditions, including: a) Power cables and control cables mainly installed in high-voltage and medium-voltage (HV/MV) substations and repetitive damped oscillatory waves appearing in the signal cable. b) repetitively damped oscillations mainly in gas-insulated substations (GIS) and in some cases air-insulated substations (AIS) or in power cables, control cables and signal cables of any installation due to the phenomenon of high-altitude electromagnetic pulse (HEMP) Wave. The purpose of this standard is to establish immunity requirements and a common reference for evaluating the performance of residential, commercial and industrial electrical and electronic equipment in the laboratory and, where applicable, for power plant and substation equipment. The purpose of this standard is to specify: - test voltage and current waveforms; - test level range; - test equipment; - test arrangement; - test procedures. The purpose of this standard is to establish a common criterion for evaluating the immunity of electrical and electronic equipment to damped oscillatory waves. The test methods specified in this standard describe the consistent method of assessing the immunity of equipment or systems to defined electromagnetic phenomena.
