  2. Generalinformation The xSpideris a graphically oriented design software for dimensioning low-voltage networks fitted with protective devices of Eaton brands.

  3. General information • The xSpider is intended primarily for designers, computational and checking engineers • Design of networks TN/TT/IT of various voltage systems up to 1000 V • Design of radial or meshed networks • Design of networks supplied from one or more different power sources • All calcualtions are based on IEC standards (voltage drops, load distribution, short-circuits, impedances)

  4. User-friendly interface allowing easy and fast design • User operation similar to standard CAD systems (eg. AutoCAD) • Independent software requiring only the operating systemof Windows95/98/NT/2000/XP or Vista • Available free of charge after registration via internet Generalinformation

  5. General information • xSpider software provides needed calculations: • voltage drops (DU) • load distribution (nominal load In / overload) • short-circuit currents (Ik“, Ikm , ….) • carries out check of suitability of cables (In, I, …) • carries out check of suitability ofprotectiondevices • calculation of impedances (Zv, …) • etc.

  6. General information • Tree structured database for all needed components • Graphical comparison of tripping characteristics • Evaluation of selectivity betweem devices in the network • Evaluation of selectivity between incoming and outgoing devices according to tables from catalogue
