ECN Forum Forums Technical Discussion Electrical Theory and Applications 2 phase neutral current?

Sparkee;

The inbalanced current of the 1Ø 3 Wire system will be 1.6667 Amps on the Center Tapped Neutral.
The "Common Load" of 1500 VA - or 12.5 Amps @ 120 VAC, will flow between the "Ends" of the Secondary Winding.

(oops, already answered! Sorry!)

Here is a crude schematic of a 4 wire Wye:



I thought for sure this schematic was re-drawn and replaced on the server, but I guess not!
Place this task on my "To-Do List" at entry # 37,525,089

Anyhow, this thread is kind of going everywhere, yet gaining absolutely nothing! (like walking to the store, then walking back using the same route, yeilds no gain in distance!).

Here's a few simple questions to ponder:

If I take ØA, ØC and the tapped Conductor from the Star Point (the common grounded conductor in most cases, AKA "The Neutral"),

* Could this be viewed as a Polyphase Setup?

* Could this be thought of as a 3Ø setup?

* Can I connect this to the Primary of a 3Ø Transformer, and achieve a 3Ø 3 or 4 wire output? (depending on the secondary configuration)

* If I connect a 50,000 Watt Pure Resistive Load (P.F. = 1.0) between Phase A and Phase B of a 480Y/277V 3Ø 4 Wire system, will the load current be:
<OL TYPE=A>

[*] 104.167 Amps,

[*] 180.51 Amps, or

[*] 60.169 Amps.
</OL>

* If a Spaceship lands in your back yard, how many cubic yards of Sand will it take to fill your Dog's House? - True or False?

I joke a bit about Electro-Techno stuff, mainly because where else can someone add up 1 + 1 + 1 and get 1.732!!!
(or 3 + 4 = 5!!!).

I think for the sake of others reading this thread - who are not as advanced in these areas of theory as others, that we stay on track with the data being discussed - and whenever possible, show references!

If you cannot upload a drawing or text, then contact me via e-mail, to make arrangements and such, and I will do the honors of uploading and embedding images to these threads.

With drawings and schematics, please complie them into .GIFs or even .JPGs first. I don't have as much "Free Home Time" as before, so converting images by me is a rare event!

Please do not take this message as any level of dicketry!
I just wanted to make a point of reminding everyone about the vast audience viewing this forum area - and that many viewers are trying to better themselves in the theory area.
Help these people by making things a little easier to follow and understand whenever possible.
