I've had quite a few private questions about my article
Re-wiring a three phase generator

Most of these have been along the line of
"My meter shows acceptable voltages in three-phase if I just
hook up L1, L2, and Neutral - and don't use L3"

That's a 3-phase, 4-wire connection with one of the "line" connections unused:

The voltages will indeed APPEAR to be in an acceptable range,
because the individual is not using proper equipment to test the system.

In UNDERSTANDING AC POWER we will explore why.

In UNDERSTANDING RESIDENTIAL AC PHASES we will look at phase-shifts.

In UNDERSTANDING HOW GENERATORS WORK we will learn how generators
are wired and hopefully learn how to identify our own.

In GUIDE TO POWER SYSTEMS we will get way too detailed and put you to sleep!
