Answer to Question 1

Tower shading can cause the blades to flex slightly as they pass the tower, creating stress in the blades. In addition to potential damage, flexing can produce an oscillation.

Answer to Question 2

Line current is measured on a given line; phase current is measured on a component within the three-phase wye or delta connection. Line current and phase current are the same in the wye connection.
