xSpider
Software tool for semi-automatic dimensioning and calculation of low-voltage networks
Graphically oriented design system for
dimensioning of low-voltage networks fitted with
Eaton circuit protection equipment.
• Design of TN/TT/IT networks of various voltage
systems up to 1000 V.
• Design of radial as well as meshed networks.
• Design of networks supplied from one or more
different power supplies.
• Possibility to simulate various operating states of the
network by disconnecting power sources and loads.
• Database of components with transparent tree
structure allowing user-defined additions.
• All calculations (voltage drops, load distribution,
impedance, short circuits) are based on IEC
standards.
• Export of graphics into DXF data format.
• User-friendly interface. User operation similar to
standard CAD systems (AutoCAD).
• Stand alone software based on Windows platform.

Voltage drops, load distribution:
• Check whether voltage drop does not exceed the
user-defined maximum value set locally for every
network component.
• Check of correct dimensioning of the circuit
protection equipment and conductors.
Component with error
(current in the line is higher than
nominal current of c.b.)
Switch off c.b.

Three-phase short circuit :
• Maximal short circuit.
• Check of correct dimensioning of the circuit
protection equipment and conductors (check of
breaking capacity).
• Check of whole network or fault in one node.
