AI Thread Summary
The discussion centers on the comparison between 460VAC/230VAC and 440VAC/220VAC transformers, highlighting that both can output the same voltage based on the actual input voltage. The nominal voltage standards vary by region, with many European countries transitioning to the 460/230 standard, while the US typically uses 480/240/120. Although the transformers may differ in kVa ratings, their voltage ratios are essentially equivalent. Therefore, the two transformer types can be considered functionally similar for most applications. Understanding regional voltage standards is crucial for ensuring compatibility and performance.

I'm using a 460VAC/230VAC single phase transformer. My customer insists wanting to have 440VAC/220VAC one instead. The ratio between the two transformers are the same. How different are the two? Are they essentially the same ?

Thank you,

Both will output the same voltage, which will be determined by the actual voltage input. I'm guessing you are in Europe? The nomial voltage can be either depending on the country (apparently, most are switching to the 460/230 standard). In the US, nominal is 480/240/120.

The two transformers may have different kVa ratings due to the voltage difference... but if you ratio them to the voltage, I bet you'll find they are exactly the same.
 

Thread 'What happens if shielded cable has short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Underwater piezoelectric sensor array receive sensitivity'

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...

Thread 'Question about bonding ground and neutral'

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...
