1." the shunt connection in four point stater is provided separately form the line where as in three point stater it is connected with line which is the drawback in three point
starter
2.In three point starter NVR (no voltage relay)is series with shunt if voltage falls certain value NVR De energized due to insufficient magnetic field and motor turned off. But in four point starter NVR energized directly from DC supply
thus the draw back of 3 point starter rectified
What else can I help you with?

Why 3 point starter is called 3 point starter?
Because it has three terminals L , F and A L - Line (connected to Supply) F - Field (connected to field of dc motor) A - Armature (connected to armature of DC motor) that's y it is called 3 point starter :)

How do you find the other endpoint of the line segment with the given endpoint and midpoint?
Add the same amount again by finding the difference of the midpoint and end point. Example: If the end point is 3 and the mid point is 9. The difference between 3 and 9 is 6 so add 6 to 9 and get 15.
