What earthing arrangement is this?

The supply is from a private transformer in a four core cable 3ph + n. The cable armour is earthed and connected to the MET. However there is also a green and yellow cable connected to the neutral terminal at the main isolator going back to a the transformer casing. The transformer is only 5 or 6 metres away. I think this must have been intended to make it a tncs supply but seems to me to just create parallel neutral conductors. Or is it tn-s-c-s? I have only been able to go off visual inspection because I could not disconnect the supply..
oh yes, thats the biggest aspect of choosing contractors here, I show people around and can usually tell if they are going to fit in. Plenty look petrified and I just know that they will be in the office every 30 seconds wanting a box moving, or complaining about something.
I tend to show electricians one of our old red spot or 100a BS3036 boards to see the reaction. It's not even an age thing, its just attitude
the other thing I like is when people have a positive reaction to permits
I have some great contractors that I can show the job, tell them what I want the end result to be, and leave them to it, next thing, its all done. That's what I want in an industrial environment. I don't want to babysit
