A.

Increases

B.

No change

C.

Zero

D.

Decreases

Answer ( Option A)

Increases

Solution

By increasing cross arm, Cwill decrease and hence K decreases then string efficiency increases. 

As the value of K approaches to zero. The string efficiency approaches to 100%.

Now string efficiency for 3 suspension type insulator is given by
