Narda Simulation Software EFC-400

Simulation Software EFC-400 Overview

EFC-400 calculates electromagnetic fields using a practically unlimited number of network elements such as conductors, line segments, buildings, and antennas. The software features fast computing speed, ease of use, and efficiency. Users can create all the needed network elements themselves or import them. The software puts all the elements together with the simulation result in an easily interpreted graphic display.

EFC-400 has been the quasi standard for the industry since 1995, with references from clients worldwide. Users include energy network operators and their planning departments, consulting engineers, railroad companies, regulatory authorities and the environmental departments of local government agencies.

EFC-400 was originally developed for determining field exposure levels caused by power supply equipment (overhead lines, transformer and switching stations) - including noise emissions and RF interference levels due to corona discharge.

The EFC-400 Telecommunication is a separate module for computing the radiation exposure due to transmitters and telecommunications equipment emitting high frequency radiation.
