Short-Circuit Verification
The challenge
During a short circuit, large electrodynamic forces act on busbars, clamps and support insulators. Underestimation leads to deformation or failure; overdimensioning to unnecessary costs.
Our approach
Nexums independently verifies the short-circuit withstand of your connection. We advise on which load cases are relevant and review the force and stress calculations in accordance with IEC 60865, including support spacing and insulator loads.
Standards framework
IEC 60865
Result
A substantiated assessment of whether the connection safely withstands the specified short-circuit current, with recommendations where margins are insufficient.
FAQ
What is short-circuit verification?
An independent verification of whether a connection — busbars, clamps — safely withstands the specified short-circuit current, in accordance with IEC 60865.
Why is this important?
A short circuit generates large electrodynamic forces. Underestimating these forces leads to deformation or failure of the connection; over-dimensioning leads to unnecessary cost.
What do I need to have the verification carried out?
The available design drawings, material specifications and the specified short-circuit current and duration. Missing data is supplemented in consultation.
