The static UPS and its electronic components influence the performance of the electrical plant and it may be affected by it.

Even if the static bypass constitutes, for the purposes of simplicity, a cable that passes through the UPS, it is in reality a semiconductor with all the limits that these components have, such as their capacity to withstand short circuit currents.

Download this white paper to understand what happens to an SCR used as static bypass in a UPS during a downstream short-circuit and review the protection strategies that the designer can adopt considering both I2t and peak current values.
