r1+r2 readings

[Benjamiin]

Im sure this has been covered before, but Im after peoples views, I am 100 percent confused by the reg that states zs may be calculated using ze plus r1 r2, but r1 r2 cannot be calculated using zs minus ze, naturally I test my r1 r2 and zs. But once I've tested my zs on a periodic for example I have already proved there is an earth or continuity of it at the end of line, so why the big dramas over not being allowed to do it?

this is because R1+R2 should be a dead test, done before the circuit is energised. and what the hell r1 and r2 have to do with it i don't know as they are end/end resistances of a RFC.

Zs = Ze +(R1+R2) because you're measuring all those things in isolation.
Zs is measured including parallel paths

I forgot a +, so automatically threw myself into the lions den haha, cheers for the replies lads

 

[telectrix]

that was my point. there is no such animal as r1 or r2 on a radial.

 

[trev]

(R1+R2) on an RFC is not the same as r1+r2

 

[telectrix]

it's about a quarter.

No, sometimes I forget to press it either because I'm a dumbass or because I've been on the lash all day

This forum is genius, I asked about testing, and now I know about a wedding up north, superb haha!

If you'd of asked the question right, you may have got better answers!!!

What else would you like to know about? We can take any thread off topic as far as you want to be taken.

EG

Greggs pasties are crap, discuss.

Jay sparks, my reply was in good humour, not meant to be sarcastic etc, sorry if it got your back up mate
