Fuse Dimensioning (DN) Siemens PSS SINCAL Protection Modules

Fuse Dimensioning (DN)

Requirements and Use Cases

When dimensioning fuses in low-voltage networks, the load current, short-circuit current, conductor cross-section, thermal destruction etc. criteria must be checked. Some of these criteria can be tested without simulation, while others, such as the k-factor test, require extensive simulation. The goal is the automated simulative verification of all these criteria, which leads to a considerable reduction of the workload.

Solution

The Fuse Dimensioning module (DN) in PSS®SINCAL checks the dimensioning of fuses in meshed and radial low-voltage networks.

Checking the correct dimensioning of fuses regarding:

• Load current
• Safety factor (k factor)
• Maximum switch off time (VDE 0100-410)
• Conductor cross section (VDE 0636)
• Thermal destruction
• Thermal load (VDE 0636)
