R S T,L1 L2 L3, U V W
« on: March 28, 2014, 01:24:14 pm »
Hello!

I want to know, what RST in three phase system means?
Is it short for some words or something?

Thanks!

R-S-T is an old German naming convention for L1-L2-L3. It's not any abbreviation, just three consecutive letters. On some 3-phase motors you might also find U-V-W and X-Y-Z for the coils.

yup, just arbitrary consecutive letters, just like naming them A-B-C

Did you even bother doing a Google search before asking here?

Sometimes a human response is better.
