June 2011 2391 exam

[Richard]

Did any of you sit it? I didn't think it was TOO bad, couple of questions I was a little unsure of but overall ok. How did you guys find it? I can never think of the bloddy questions afterwards!

 

[kennydeeee]

That's the way I read the question put down no effect for the first part put down 500v dc for the second part then went back and change it to 250v dc and record as a limitation if the lamp cannot be removed think I lost a mark for this 1

State the effect on measured values of insulation resisLance of a230 V circuit if an​

insulation resistance test is carried out

i) between live conductors to earth with a tungsten lamp in circuit

ii)between live conductors with a switched fused connection unit, having a
neon indicator. left in the off position.

Any answers?




Is that exactly how the question was written in i?

'Between live conductors to earth' could mean between L+N joined together to earth in which case the lamp would have no effect.

Not that I'm in any way suggesting ambiguity in a City & Guilds question!

Yes, I nearly got caught out on that one and only noticed it when I was checking my answers over and managed to change it thence. It should have no affect as the test is to earth.

It just says state the effect....So if the neon is out of circuit, then no effect.....surely!!

 

[abingdonjon]

Totally screwed up on that question then. It's so obvious when answers are in front of you, and you draw a complete blank at the time! I stated it would record an inaccurate reading for first answer, 2nd answer stated the entire length of the circuit will not be tested.....duurgh! live and learn I guess!

 

[kennydeeee]

Just marked mine up think I got in around 85%

 

[72-van]

85% wow

 

[kennydeeee]

Just hope it's enough with the floating pass mark

 

[72-van]

Well if your just hoping for a pass with more than 85% i aint got no chance at all

I was feeling quite content with myself when i got a few questions i knew the answer to .Shame i had so many bad guesses..maybe next time

Chin up mate I'm sure you will do fine

 

[sparks_114]

The anxiety of the wait has hit me the first day after the exam, and still with me. The clock will tell but it's a case of have I got it or have not for the next month or two. We're all in it together fellas. Hope we get through and be back to tell our story.

 

[kennydeeee]

Can any1 recommend a good case that would hold an mft A clamp meter couple of sets of test leads and possibly a netbook

I know exactly what you mean!!

Perfect example of me not reading the question properly. Funny how sometimes your brain only sees what it wants to see.. Of course the lamp would have no effect when testing to earth.
RTFQ!!!!!

 

[kennydeeee]

I messed the second part of this question up said 250v dc incase the lamp would be damaged I'm a --- lol

Abingdonjon;

Could you send me a copy of the paper please. My email address is [email protected]

Thanks

 

[abingdonjon]

done....enjoy!
