EMC Seminar Schiphol (part 4)
Description
EMC Seminar Schiphol (part 4)
Ensuring Continuity of Business Processes in and around the Terminal Complex by EM zoning and performing EMC measurements (part I).
A large number of technical installations and systems are located within the Terminal Complex at Schiphol Airport. These installations and systems comprise sensitive electronic equipment for information processing, telecommunications (data and voice) and detection of persons and baggage, as well as potentially disruptive transport systems and high-frequency transmitters. The undisturbed operation of the assembly of these devices and systems within the limited space of the Terminal complex requires careful planning of emission and immunity, or Electromagnetic Compatibility (EMC).
Based on the design basis EMC (2004 and updated in 2008), an EMC management plan has been implemented for the Terminal complex, EM zones have been established for all 13,000 spaces and EMC measurements are being taken on an ongoing basis. The measurement results confirm that minimum EMC requirements should be imposed on electrical and electronic equipment and systems to minimise the EMC risk to operations. A distinction is made here between residential- light industrial- and heavy industrial environments. The choice of ICT network cabling and installation technology also appears to play a major role in the eventual immunity of equipment and systems to interference.
During this EMC seminar, various examples and specific installation requirements for equipment and systems will be discussed and the EMC effect on the physical layer of industrial fieldbuses will be explained (a common problem in lifts, for example)
- Long cables cause resonances, resulting in voltage spikes, which are fatal for the insulation of the motor windings and considerably shorten the lifespan.
and that measuring in a 600V CAT III DC bus with a scope is not without danger.
In addition, wireless systems require careful planning of transmission and reception frequencies and transmission powers, and consideration should be given to unwanted signals that might be generated by neighbouring equipment as by-products.
In short, controlling EMC in the various areas and spaces is possible, provided the EMC specifications are met during the construction of installations and systems and the installation regulations are followed during implementation.
Controlling EMC is a permanent necessity, because it partly determines the reliability of equipment and systems.
In fact, controlling EMC is essential to guarantee the continuity of critical business processes.
During this seminar, various measurement results and the effect of applying installation regulations for EMC are presented on the basis of various practical set-ups.
