Ans. to #1

Active stall turbines regulate power by increasing pitch to stall conditions once rated power is achieved. The power is maintained at a constant level by moving the blades in and out of stall conditions.

Ans. to #2

Line voltage is measured between lines; phase voltage is measured with respect to the components within the three-phase wye or delta connection. Line voltage and phase voltage are the same in the delta connection.
