Arrows for Earth Fault Current Path

I always thought the current flowed toward the fault. maybe things have changed.

That's funny. So did I. Perhaps things have changed since 1942?

Of anybody Crabtree you should know the EU will change the rules contrary to the laws of physics and common sense.

That's all well and good IF the circuit is simple, it does get more complex with multiple paths, varying impedances and when multiple sources are involved.

<cringe> Complex software is only as good as the person entering and analysing the data. I once had to explain to a consultancy why their design and complex design software-generated drawings for a wind farm were wrong because they didn't take in to account that the wind turbines were generators and if the line fault occurred right next to them (and the wind was blowing) the generators would be providing the majority of the fault current.

In the end I drew pretty pictures with arrows showing the current flow in the event of a fault because a simple explanation was not enough to get this point across.

The moral of the story (and the answer to the original poster's question) is that education and experience are required for more complex systems, so best to hit those books and search the internet for general literature on the subject of complex circuit analysis.
