AI Thread Summary
Using a transformer to step down voltage from 240V to 24V and then back up to 240V does not reduce electricity consumption, as billing is based on kilowatt-hours, not voltage. The proposed setup would actually increase energy loss due to inefficiencies in the transformers, resulting in higher electricity bills. For every amp drawn at 240V, significantly more current would be required at 24V, leading to increased power consumption. Additionally, the transformers may generate heat, further impacting efficiency. Overall, this approach is not practical for reducing energy costs.

I was thinking that the possibility may exist that I could install a fused disconnect for my line in from the power company and hook it to a 240v-to- 24v step down transformer, use a whip to connect to another fused disconnect with a 24v-to-240v before entering the panel. my theory is that my draw from the power company would only be 24 volts and I would be stepping up the voltage myself with my own transformer thereby reducing my consumption and my bill. So am I insane?

Assuming it is like the US, you are billed by power consumption (KwH) - not voltage.
At the end, you're taking the long way back to getting where you started (240). Since nothing is 100% efficient, you would have some losses along the way. Therefore, your bill would actually be higher.
 
Thank you.

Your draw of 24 volts would be from the step down transformer, which would be transforming that to a draw of 240 volts. BTW, for every amp you would be pulling at 240 volts from the step up transformer, it would be pulling 10.4 amps from the step down transformer, which would in turn be pulling 1.08 amps from the power company. Expect your bill to be a bit higher. Expect some warming in the room where they are located. Be sure to invest in some really thick copper for the 24 volt wiring.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
