SVPWM: space vector generation star point shifting - effects?
I keep seeing that the space vector generation (as a part of a FOC) is generated around DC Link / 2. What effects would be expected if the (in this case isolated) star point were permanently shifted?

MCP39F521, a Triac (T610), Load on Neutral & Measuring V and I
I'm trying to build a AC “power bar” with metering per “outlet”. The 2 most interesting chips I found are the Microchip MCP39F521 and the Allegro ACS37800. Due to costs, I've chosen the former. The ...

Measuring Line to ground voltage of an ungrounded, isolated output (secondary) in an single phase 400/24v transformer
So we have this electrical control panel in which we have a 24v dc and a 24v ac circuit both. The 24v ac is coming out of a 400/24v transformer. The transformer primary is being fed from a 3-phase ...

Running long underground line without neutral or safety ground using transformer, is it to code?
My prior question asked about a single wire earth return [SWER] system. Both questions are aimed at meeting the same end requirement but this is a sufficiently different method that many of the issues ...

Effect of the neutral current to a system when a 3-phase facility is used as unbalanced
Normally 3 phase-systems are used for balanced loads like in 3-phase AC induction motors. I know that in a balanced star configuration the total current across the neutral is zero.
But what if each ...

What is maximum possible current in neutral wire in three phase connector?
What is the maximum possible current in neutral wire in eg. 3x16A three phase connector? Is it possible that current leads or lags more than 90 degrees?
Edit:
Could the maximum be
16A∠0° + 16A∠(120°-...

Do 2 conductors (1 grounded via resistor) reach equipotential, before surplus electrons drain to earth?
Case I: a negative conductor makes contact with a neutral conductor. Negative donates some electrons to neutral, until there is 0 potential difference. Then they both are slightly negative.
This ...
