EFC-400 - Simulation Software Computation of low frequency electric and magnetic fields Industry standard for low frequency simulation since 1995 Maximum strength performance from calculation speed, ease of use, and the practically unlimited number of network elements Maximum cost-effectiveness in use, as users can create and import the necessary network elements themselves Principal users: Energy suppliers and their planning departments, consulting engineers, railroad companies and network regulation authorities Import and interpolation of measurement data All network elements are visible: 3D display “What you see is what you get” Worldwide user references available from the Narda homepage Product description The EFC-400 software has been specially developed for computing the electric and magnetic fields around energy supply installations. The EFC-400ST version is the least expensive alternative for computing the magnetic fields of transformer stations or switching substations. The EFC-400LF version is capable of computing the electric field strength of overhead cables with up to 1000 sections as well as the magnetic flux density. EFC-400PS additionally allows computation of noise emissions and RF interference levels due to corona discharges. ® The Name and Logo are registered trademarks of Narda Safety Test Solutions GmbH and L3 Communications Holdings, Inc. – Trade names are the trademarks of their respective owners.

General technical description Compatibility between the different EFC-400 LF versions is 100% guaranteed at all times because the user interfaces of EFC-400 and "EFC-400 Station" use the same source text. 1. Secure investment Users benefit from the fact that the application has been tried and tested over many years in practical use, so there is no risk in choosing "EFC-400". The wide distribution of the software ensures long-term development and technical support. Many power utility companies attest to the stability and effectiveness of the product, particularly since the two-year warranty...

Description of Version EFC-400LF 1. Simulation of high-tension routes To simulate high-tension routes, users simply have to select masts and system configurations from a library. If the route is changed, e.g. by moving mast positions, the conductor path is automatically corrected. 2. Provision for phase and frequency Field sources of different frequencies (0 - 30 kHz), such as the overhead wires for long-distance or urban railroads, can be processed with correct phase. Comparison with measured data is possible, with optional interpolation. Magnetic field of a switching substation 3. Dynamic...

2. Representation of noise level at any location The method used can handle any arrangement of conductors, taking the slack span into account. The procedure is able to cope with the orientation, spacing and surface field strength of each individual segment. The results are shown as contour lines, just like the electric field strength. The noise level can be read off for every point beneath an overhead cable or within a transformer substation. The results converge towards a limit value as the number of segments increases in the same way as the computation of electric field strength. The...
