When a three-phase short circuit occurs upstream, ES is decoupled from the system-side circuit, and the SCC flowing through the system side is unrelated to whether any ES is connected. When a two-phase short circuit occurs upstream, the grid-connected-point voltage satisfies (dot{U}^{(1)} = dot{E}_{s} /2) without ES connected, …
Zener diodes are one of the most commonly used circuit protective device, thanks to their ability to clamp voltage. If used in forward-biased mode, they will clamp voltages to around 0.6 V like any other silicon diode; however, unlike silicon diodes, when used in reverse bias mode they will clamp a voltage a specific value.
