EN IEC 61000-4-18 Electromagnetic Compatibility (EMC) - Part 4-18: Test and Measurement Techniques - Damped Oscillating Wave Immunity Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN IEC 61000-4-18 testing. This part of IEC 61000 focuses on immunity requirements and test methods for electrical and electronic equipment under operating conditions with respect to:

EN IEC 61000-4-18 Electromagnetic Compatibility (EMC) - Part 4-18: Test and Measurement Techniques - Damped Oscillating Wave Immunity Test

  • Repetitive slow damped oscillating waves (HG/MV) substations occurring mainly in high voltage and medium voltage installed power, control and signal cables;
  • Repetitive fast damped oscillating waves that occur in power, control and signal cables installed in gas-insulated substations (GIS) and in some cases also in air-insulated substations (AIS), or in any installation due to the phenomenon of high-altitude electromagnetic pulse (HEMP).

The purpose of this standard is to establish a common and repeatable reference for assessing the immunity of electrical and electronic equipment when subjected to damped oscillating waves at the supply, signal, control and ground connection points. The test method documented in this section of IEC 61000 describes a consistent method for assessing the immunity of an equipment or system to a defined phenomenon.

This standard defines:

  • Test voltage and current waveforms;
  • Test levels ranges;
  • Test equipment;
  • Calibration and verification procedures of test equipment;
  • Test setups;
  • Test procedure.
