Problem with PSSC on three phase supply

[sparksburnout]

I have a domestic premises (it was once a shop) that has a three phase supply, although only one is being used now. I am using a di-log 9083P tester, and when doing a Ze test am getting 23KA as the reading for PSC, with 0.01 ohms as the loop resistance. I am getting a Ze of 0.35 ohms and a PFC of 565A. The values for PSC and L-N loop impedance seem unbelievably low to me? I am not sure where the local transformer is but it is not next door, I think it is about 400yds away. System is TNS. I have looked at the thread in the I&T forum, and used the method of inserting an impedance in the earth lead of the tester, but I am still getting the same readings, which as far as I can see you would, as it is for low Ze not low PSC. I have used the tester on about 3 other installations, and it is giving expected results. Could it be possible that these values are correct? In which case the main switch and breakers are well underrated!!

Errr, Who know's if you even had your own Distribution TX??

actually we dont, but quite close to a transformer.

We have a big grey thing at the top of our street surrounded by a green steel fence.

I'm thinking about sending a picture of it to Tony - he likes things like that.

I agree.

I like Industrial Archaeology (think Fred Dibnah) and all that sort of stuff, Rockabilly, Rock n Roll, Southern Boogie, Fleetwood Mac, Dire Straits, photography, Toyota MR2s, Duck Dysentery on TV and a very funny Pikey woman.

i also collect spades and have a decent colletion, my best been a 1930's cast steel digging spade double braced on ash shaft with a box "D" handle.

Yes .... he was a grand bloke.

I must say I admire blokes who can call a spade a spade.

Tidyboiler tells me her Dad ( a tough little Pikey bloke) always called a spade a spade and often to his face.

I have a collection of woodworking tools that were made and used by my Grandfather in a very impressive tool chest that he made himself.

I think to a collector they will be worth some money.

I used to get around a lot but haven't been able to for the past couple of years cos I've not been well.

I always wanted a good camera outfit and after about 30 years finally got it - all packed in a big fluck off rucksack that I can't carry .......

Thank you.

I appreciate that, the past months since October have not been much fun, but could be worse. I think I'm picking up a bit now since Friday when Tidyboiler almost literally dragged the GP by his balls from his full surgery direct to my bedside!

I had his full attention from then on.

 

[pepparz]

well done tidyboiler!
