Gary102 Posted February 18, 2020 Share Posted February 18, 2020 Hi Guys, I’ve got my vetassess exam soon in London. Could anyone please help with classroom theory side. What to revise for? Thanks. Quote Link to comment Share on other sites More sharing options...
mrsmac Posted February 18, 2020 Share Posted February 18, 2020 Have a look on the VETASSESS website - Guides and Fact Sheets, here: https://www.vetassess.com.au/skills-assessment-for-migration/trade-occupations/guides-and-fact-sheets Quote Link to comment Share on other sites More sharing options...
Gary102 Posted February 18, 2020 Author Share Posted February 18, 2020 I have gone through the vetassess information and it seems a bit vague. Was hopefully looking for someone who has done the exam recently, who could points out the key points. Quote Link to comment Share on other sites More sharing options...
mrsmac Posted February 18, 2020 Share Posted February 18, 2020 Sorry, i did not realise. If you are using an agent, could they perhaps give you some advice about what to expect? They are likely to have had feedback from other clients. Quote Link to comment Share on other sites More sharing options...
wrussell Posted February 20, 2020 Share Posted February 20, 2020 Do you know which end of a megger the bullets come out of? Quote Link to comment Share on other sites More sharing options...

wrussell Posted February 20, 2020 Share Posted February 20, 2020 And if you know how to switch on a dmm, you will be ok. Quote Link to comment Share on other sites More sharing options...

Get on top of motors and control wiring to latch in a motor i.e stop start e-stop etc. I was asked to draw this and then wire it. Not hard hard at all. Abit about distribution and transmission voltages. Star delta and you will be asked which is which and why and when they are used. Quote Link to comment Share on other sites More sharing options...
Gary102 Posted February 20, 2020 Author Share Posted February 20, 2020 Thanks Liam13. could you help out with the star/delta questions please. Quote Link to comment Share on other sites More sharing options...
Joe/Rose Posted February 20, 2020 Share Posted February 20, 2020 I wouldn’t take this assessment to for granted, plenty of people have not made it through the day.... two guys failed the theory part on my day. Definitely brush up on AC motor theory & general electrical principles. Quote Link to comment Share on other sites More sharing options...
Joe/Rose Posted February 20, 2020 Share Posted February 20, 2020 As regards stat delta etc. Just look online if you don’t know already, you will be expected to know which is which & how to wire a DOL control circuit in practice. Don’t mess this bit up. Quote Link to comment Share on other sites More sharing options...

Just recognising star and delta connections etc. He may ask you how is this motor connected. I had questions on starters aswell. Just get your head around the basics of starters. DOL etc.. You will be ok. As joe mentioned get your head around the DOLas you will be wiring one with a start, stop and e stop. There is plenty of drawing on google for this.. I wouldnt worry but as joe said people do fail but put the time in and you will be ok. Any questions just yell Quote Link to comment Share on other sites More sharing options...
Gary102 Posted February 21, 2020 Author Share Posted February 21, 2020 I get the circuit side of the dol starter. When they ask about star/delta is just as simple as star requires a neutral and delta doesn’t? thanks Quote Link to comment Share on other sites More sharing options...
Joe/Rose Posted March 15, 2020 Share Posted March 15, 2020 Hi Gary, with all due respect; if your asking whether a star/delta configuration has a neutral connection, you need to do some serious revision. It’s abit tricky & very lengthy to start teaching AC/DC motor theory & starter connections via this thread. Watch some YouTube video & buy a decent electrical principle book.

Joe/Rose Posted March 15, 2020 Share Posted March 15, 2020 A decent electrical principle’s book (although expensive) is; Electrical trade principles A practical Approach by Jeffery Hampton & Steven Hanssen. this is actually what Future skill suggest you buy for all related studies in electrical theory. It’s helped me a lot to be honest. For the assessment day; they just want you to be able to explain that you understand what the discrepancy is between different AC/DC motors & starters, remember that VSD drives are another type of control for a motors, aside star/delta & DOL etc. You might want to brush up on Power factor correction, how this is used & where. Flourescent starters, batteries also. Regarding the fault find exercise, don’t over complicate it, just stay relaxed & think as you normally would logically, it’s wasn’t hard to be fair. Good luck.
