motor diversity
(OP)
I've entered a group of synchronous motors in SKM and tries to compare the fault currents at the buses when load (around 22kW) is at 60% compared to 100%.
The results I obtained is the same, is that normal. I believe not!!

The motor contributions to fault current may be a very small percentage of the total fault current on a stiff system.

Each load is about 22kW but the total load in each bus is less than 100kW.
Just to confirm wht davidbeach is saying about the motor contribution to the fault current, if the load is running at 100% and its x/r ratio is 3, and if now if the load is running at 60% is the x/r ratio different?

True?

That said, as was previously pointed out, for a stiff source, the motor contributions might not be very much.
