EMC Technologies receives further NATA accreditation

Testing house EMC Technologies has advised that it can now provide NATA accredited testing to IEC 61000-4-18 or EN 61000-4-18: Electromagnetic compatibility (EMC) – Part 4-18 : Testing and measurement techniques – Oscillatory wave immunity test.

IEC 61000-4-18 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, with regard to:

• repetitive damped oscillatory waves occurring mainly in power, control and signal cables installed in high-voltage and medium-voltage (HV/MV) substations;
• repetitive damped oscillatory waves occurring mainly in power, control and signal cables installed in gas insulated substations (GIS) and in some cases air-insulated substations (AIS), or in any installation due to high-altitude electromagnetic pulse (HEMP) phenomena.
   

Compliance with this standard will establish the immunity requirements, using a common reference for evaluating in the laboratory, of electrical and electronic equipment intended for residential, commercial and industrial applications, as well as of equipment intended for power stations and substations, when subjected to damped oscillatory waves.

Test voltage, current waveforms test equipment and test procedures are defined in the standard. Test levels are given for slow damped oscillatory waves (100 kHz or 1 MHz) and for fast damped oscillatory waves (3, 10 or 30 MHz).

This testing service is claimed to be unique in Australia, and is now available to manufacturers and suppliers of equipment to be used in MV/HV power stations. The service complements EMC Technologies’ NATA testing to related standards IEC/EN 61000-4-8, IEC/EN 61000-4-9, EN 61000-4-10, IEC/EN 61000-4-12 and IEC 61000-4-16, all of which are provided under the one roof.
