Error 2343

Morning Duncan, so we are having a problem with opening other Hevacomp files on different PCs in the office so I am reinstalling the program using the files 1-5 shown in the picture. Once we get to 4, it fails with this error, any ideas? I read on another thread how to solve the files not opening and showing errors, hence my re-installing to make sure the PC's were all up to date with each other.

Large loss of PSCC across first leg of circuit from Transformer to Main switchboard

Afternoon all

I hope someone can shed some light on what i think is a problem with hevacomp connect, i am currently working on a large project and at the transformer, we have a fault current of 24kA but 10m upstream we have a fault current of 7.9kA so losing 17kA through 3 no. 185mm2 SWA cables.

I thought this may have simply been an error on this project due to entering something incorrectly but a colleague checked a calc they produced and the same happens, it seems the board downstream will let nothing more than 3kA through.

I have tried changing the protective device and this changes nothing on the fault current which remains at 7.9kA.

Any ideas / help would be greatly appreciated.
