LEVEL 3 -Assignment Help for 3 faults - FIRST FAULT RING CONTINUITY

[Foxhound]

Hello there,

I'm currently taking my Level 3 and have been given an assignment to do which I have all most finished but I was wondering if anyone could use their infinite electrical knowledge and help me out with 3 faults that I need to identify and rectify? I will lay out below what I have so far written out and if anyone can point me in the right direction ill be well chuffed. Thanks

Ring 4 - On testing the ring where all the conductors are the same size they test (Note that this all the information available)

E1 and E2 = 2 Ohms

N1 and N2 = 2000 Ohms

L1 and L2 = 2 Ohms

The Fault

Now my first inclination is to say Open circuit on the Neutral because as we know from the question that all the conductors are the same size. An Open circuit situation would mean there is a break in the continuity of the circuit producing a an increased risk of an overload else were in the subset of the ring but could it also point out just a high resistance at one of the terminals? Or indeed more than one break in the neutral?

To Rectify the Fault.

Now I have idea how I would go about this but its is just trying to articulate it in away that doesnt take up the

Guys I had the answer written out for you lot to check but some reason the website only saved the top portion of my thread as it signed me out

Any ideas id appreciate it thanks

Thanks for the reply,

Right I've banged my head against wall. I think you could be right. A break would get a reading because...the conductor is broke in half!!!. Because I'am getting a reading could suggest exposed conductor is in direct contact with something giving me the high reading.

I'm i right or still stupid?

Sorry i meant to say you WOULDN'T get a reading from a break in the conductor hence infinity reading

Right...you're measuring the resistance of a single conductor from one end to the other.
In this case...
If you used an IR meter, it would almost certainly read zero.
If you used a LoOhm meter, it would probably read out of range and be mistaken as open circuit.
If you used a regular DMM, it would 2000ohm.

All depends on the range of the instrument you're using.
The question doesn't specify which test instrument was used (it's irrelevant), just the value measured.

Thanks mate,

right ok that makes sense. so ill just go with the 2000 ohms value and treat it as a high res like the first reply said. So this Isn't an open circuit but a loose connection poor join etc?.

Sorry for being a bit slow

As I said earlier.. Treat the neutral as a SINGLE lenght of wire with some joints in it. FORGET IR here .... Its NOT complex at all.
