reactive current during a fault
reactive current during a fault
(OP)
when there's a fault and reactive current is being injected into the power system, wouldn't this reactive current contribute to the fault current?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Source impedance plays a larger role in determining power factor angle of current flowing toward the fault (when compared to a voltage phase reference upstream of that source impedance). Typically inductive (Cables, transformers).

The injected fault current will provide support of the voltage and of course will be only a small portion if compared to the fault current coming from the network side.
The injected fault current will increase the total fault current of course but that is one negative aspect of having a "stronger network". on the plus side this will aid in supporting the voltage!
