Design for EMC - Systems and Installations

This course is available as an in-house training course, please contact us for details.

Learn how to avoid electromagnetic interactions that cause delays and increase costs

This course describes practical EMC engineering techniques for achieving reliable operation of custom-designed equipment, systems and installations. The techniques are described using the example of industrial equipment, systems and sites, but they can be used equally effectively for everything that involves connecting electrical or electronic units together with cables to construct systems or installations of any kind, whether fixed or mobile including military applications.

The practical techniques will help reduce project and financial risks for systems and installations that involve electronics.

COURSE CONTENT:

Day 1 – EM Phenomena

The three parts to every electromagnetic interference (EMI) event and four types of EM coupling, EM phenomena in; long cables, conductors, electrical power supplies, EM phenomena caused by electrical power use, EM fields from intentional and unintentional radiators, electric and magnetic fields from electrostatic discharges, EM weapons (intentional EMI), Comparing immunity test standards with real life EMI, intermodulation and demodulation, interference with; analogue devices/circuits, digital devices/circuits, software, electro-mechanical devices.

CE + CE does not = CE!

Meaning of CE Marking, integrating CE Marked equipment together, why this does not result in a CE compliant system neither technically nor legally, what to do instead.

Good EMC practices, introduction

EMC Directive (2014/30/EU) fixed installation requirements, lightning protection for electronics (BS EN 62305), IET Wiring Regulations (BS7671), overview of the overall EMC control procedure.

Good EMC practices in general use

Buying electronic equipment, power distribution systems and power quality for EMC, galvanic isolation for EMC, reducing the accidental RF-antenna efficiency of cables, segregation (zoning) of sites, equipment, and cables, using a bonding ring conductor (BRC), cable routing, and correct shield termination at both ends, galvanic isolators and PECs, creating an RF reference, RF-bonding techniques for metalwork and cable shields.

Day 2 – EM Mitigation Techniques

EM zoning, safety earthing/grounding for safety and EMC, mesh-bonding of common bonding networks (MESH-CBNs), and of insulated bonding networks (MESH-IBNs), damping the common mode loop, what to do if you can’t use mesh-bonding, filtering power and signals for cabinets and EM zones, shielding for cabinets and EM zones, surge and lightning protection.

Preventing Corrosion

Electro-galvanic corrosion, electrochemical metal groups.

Maintaining Good EMC Performance over the Operational Lifecycle

Through life EMC maintenance for screening, cables, filters, relevance of upgrades and enhancements.

Useful References

Usefull books and publications.

KEITH ARMSTRONG

Cherry Clough Consultants Ltd

Keith Armstrong, C.Eng, FIEE/IET, EurIng, ACGI of Cherry Clough Consultants Ltd, UK, on behalf of TÜV SÜD: Keith’s early experience was in solving real-life interference problems in high-technology products, systems, and installations. This led to the formation of his own company providing a wide range of EMC services and the publication of papers and books including “EMC for Systems and Installations”, co-authored with Tim Williams, which is the foundation for this course. Keith’s professional activities include chairing IET and IEEE committees on EMC and functional safety and he is UK representative on the maintenance team for standard IEC 61000-1-2 (EMC and functional safety).
