i've ordered this transformer; will test with this and post results. Thanks for your helpPNGMK wrote:Mmm. I bet that's an auto transformer but can't be sure without a meter. I'd recommend something like this https://www.amazon.com/ACUPWR-AUD-1500- ... ransformer
Thanks you so much for your help. I had this transformer delivered over the weekend and it fixed the problem. As it turns out, it was a grounding issue.PNGMK wrote:Mmm.

Well between myself and StrongEagle and the others you have a few decades of electrical engineering experience contributing. Glad to see the issue resolved.watours wrote:Thanks you so much for your help. I had this transformer delivered over the weekend and it fixed the problem.

You are a genius; and thank you so much once again for recommending a great product.
Unfortunately "portable appliance" is not defined and:PNGMK wrote: No person shall use an auto-transformer to supply electricity to —
(a) a socket-outlet;
(b) a portable appliance, unless the auto-transformer is contained therein;
(c) an electric toy; or
(d) any extra-low voltage circuit.

This specifically bans stand-alone autotransformers (as they are not contained in the appliance they are plugged into and of course they are fitted with a socket-outlet). This is a good thing. Unfortunately the tards at Sim Lim don't think so.
It's a typical Singapore consumer screw job. Business uber all. Selling a dangerous or completely worthless product? No problem. No recourse for consumer. Consumer complains? Seller sues under libel laws, now consumer is screwed two times.PNGMK wrote:Yeah well appliance when I last read the Aussie regs was any none permanent electrical device. Sounds like they left a gap there.
Honestly if I had an auto transformer blow something up I'd take it to the SCT. The act is clear in intention if not in literal language. However the most irritating thing about this shitboxes is that they trip out the ELCB's. Everytime someone complains to me that their ELCB is tripping it comes down to the one of these devil black boxes plugged in somewhere.Strong Eagle wrote:It's a typical Singapore consumer screw job.

It is a flawed design that is used because it is cheaper to make. In a standard transformer, there is a primary coil or winding and a secondary coil, both wound onto a common core. When alternating current flows in the primary coil, it generates a magnetic field in the core, which in turn generates a current flow in the secondary coil.bgd wrote:And the problem is a flawed design or just poor implementation?
How do you tell an auto transformer from an ordinary one?
