Brief Overview of Phenomena Rptitive damped oscillatory waves are phenomena associated with the opening and closing of high voltage (HV) busbars in high voltage (HV) and medium voltage (MV) power transmission stations. The physical environment influences the fundamental oscil驭lation frequency and repetition of the impulses. The most common type of switch used in power distribution is an air insulated type which has been measured as generating damped oscillatory impulses up to 1MHz with a repetition rate up to 400Hz. Damped oscillatory impulses up to 1MHz are termed "Slow Waves". The modern trend...

iccessories and Options External Three Phase Couplers Damped oscillatory wave testers can be extended with automatic or manual three-phase coupling networks. The CDN2000-06-25 and CDN3000A-06-25 can also be used for EFT, CWG surge and ring wave. Coupling path selection is either from the MIG firmware, from GENECS and TEMA software or manually on the CDN front panel (manual version only). The coupling networks fulfill the requirements laid down in the IEC 61000-4-4, IEC 61000-4-5, IEC 61000-4-12 (ring wave), IEC61000-4-18, ANSI C37.90 and ANSI C62.41 standards.
