It is zeroat the center , where (by symmetry) one can see that the threecharges individually produce fields that cancel out.In addition to the center of the triangle, the electric field lines in thesecond figure to the right indicate three other points near themiddle of each leg of the triangle where E=0 , but they are moredifficult to find mathematically.
