damped oscillatory wave Based on common installation practices, which foresee the use of shielded cables with the screen earthed at both ends on the earth network, the recommended selections of test levels for damped oscillatory waves for the equipment ports are the following: Level 1: Ports connected to cables running in a limited area of the control building Level 2: Ports connected to cables of equipment in the control building and relay house (kiosks) The equipment concerned is installed in the control building and relay house Level 3: Ports connected to cables of equipment installed in the relay house The equipment concerned are those installed in the relay house For these equipment, level assumes the value of 2,5 kV Level 4: Slow damped oscillatory waves are not applicable to equipment for use in electrical plants, particularly HV substations, while fast damped oscillatory waves are applicable Whenever this level seems to be necessary, proper mitigation methods should be adopted Level x: Special situations to be analyzed The test levels should be selected in accordance with the most realistic installation and environmental conditions For HEMP applications, the HEMP generic standard IEC 61000-6-6 describes the specific conditions for applying levels to as well as level x – 35 – BS EN 61000-4-18:2007+A1:2010 EN 61000-4-18:2007+A1:2010 (E) Bibliography [1]
