Switching transient study and snubbers

Switching transients are some of the most harmful types of power anomalies. Often initiated by a sudden change of circuit conditions, the resulting overvoltage can damage even the most rugged system components.  Eaton has the solution to safeguard your systems.

Switching transients can result from:

  • Capacitor switching
  • Transformer energising
  • Fault current interruption
  • Electrical distribution system loads switching on and off

Eaton’s switching transient study, combined with our customised snubber design/build/implementation services, offers optimal mitigation against even the most severe switching transients. We can help protect your valuable equipment investment against these damaging anomalies.

A turnkey approach to mitigating switching transients

Eaton’s comprehensive analysis evaluates pertinent system components to drive an optimal approach to mitigating switching transients. From building a system model and simulating switching-induced transients to calculating voltage and current transient magnitudes, our expert engineers will quantify the problem, predict exposure and risk, recommend the optimal and most cost-efficient corrective solution — then verify results.

A customised snubber solution to match your needs

Eaton custom-designs and builds snubbers to meet your specific requirements and physical space restrictions. Basic snubber components can be enhanced with protective features including voltage indication (glow tubes), continuity verification (current sensors) and fusing with blown fuse indicators. Eaton’s field service engineers are experienced in snubber installation and conduct testing to verify operation.
