Good afternoon, as far I know phasers always rotate ccw. However I find in specialized literature both cw and ccw scenarios - see attached example. Do applicable standards require a specific 3Ph rotation sense? Is it different for generators than for motors?
My other concerns referes to transformations, Regarding the Clarke transformation, β component can either lead or lag α component depending on rotation sense. Which is the correct option i.e β leading or lagging? Are they both acceptable and solely depending on the rotation sense of generator/motor?
Would you kindly recommend a paper for further information?
Thanks in advance and best wishes!
