Questions
Introduction (1): Who is the SNCF/EMC team ?
• Electro-Magnetic Compatibility (EMC) expertise and studies service part of the telecommunication department within the SNCF engine ering
• 30 years of experience and improvement to guarantee the EMC compatibility of the
railway system within its environment in all kind o f railway projects: High Speed Line
(TGV), urban networks, power supply systems, tramwa ys, international activities…
08/11/201108/11/2011 4
• Engineering and research activities performed by a team of 8 engineers & PhD,
and thesis (first completed in 2010, second since 2011)
(TGV), urban networks, power supply systems, tramwa ys, international activities…
• Self-developed modelisation and calculation software s
Introduction (2): EMC problematic within the railwa y system

• Vicinity of high voltage networks perturbating low current installations
• Constraints in terms of operation reliability and p eople safety
• Need to anticipate the interferences in order to op timise the costs of the infrastructure

• Large distance network (dozens,hundred of kms)
• Multiple itineraries and ramifications
• Parallelism and electrical discontinuities dependin g of the installation’s configuration
Advantage of GIS tool (1): geographical problematic
08/11/201108/11/2011 8
Need to take into account the relative position of the different circuits, with the right scaling, and to simplify t hem for calculation

Projected point not part of the circuit => no influence d>dmax => no influence
Relative position between the different networks : without GIS
• Use of a digitalizing table with optical pen
• Paper map support (IGN)
• Hand-made paper-based drawing
Advantage of GIS tool (2)

• Drawing without geographical informations
• Long and difficult task
• then use of calculation routines running on UNIX-ba sed computer
• Use of a GeoReferenced database of the SNCF network
• Numerical mapping support (IGN)
• Various possibilities of drawing and manipulation o ffered by GIS softwares like ArcGIS
Relative position between the different network: with GIS
Advantage of GIS tool (3)
08/11/201108/11/2011 11
• Accurate/geolocalised/exhaustive mapping with real geographical informations
• Faster, easier and safer work, re-usable and more f lexible
• Use of a calculation customized plug-in tool based on the UNIX kernel

Necessary input data
• Input data are Multi-Frequency : calculation by CAR YN possible for several frequencies in the case of induction on Telecom Networks (audible range o f perturbation is max. from 800 Hz to 3300 Hz)
• Input data provided by the electrical network opera tor or determined by our other calculation tools and then interpreted by CARYN and associated to each polyline

Advantages of GIS+CARYN utilisation
• Ergonomic, accurate and exhaustive treatment with t he GIS functionalities
• Ability to use the GIS entity classes to perform cu stomized treatments ( like « surface » shapes to weight results by areas with parameters such as ear th resistivity, tunnels, urbanism… )
• Multi -frequency treatment, results validated by measureme nts on various circuits by the public
08/11/201108/11/2011 26
CARYN’s evolution
• Taking into account more and more complexified netw orks, at increasing frequencies (XDSL, … )
• Statistical studies such as biological effects: usi ng 3D ?
• CARYN’s outputs approved by french rail manager, hi gh voltage lines operator and public telecoms operator through conventions as reliable mean of ex pertise for projects expertise ans costs
• Multi -frequency treatment, results validated by measureme nts on various circuits by the public telephone operator
