Question 9)
As in Figure 2.14, 500 Kv voltage is applied to a planar electrode system with four insulating layers in
between;
a) Calculate the stresses and electric field strengths in the layers.
b) Calculate the quality of the system. (S = 400 cm?, E0 = 8,854.10-12 F/ m)
c) Show whether the whole system can be punctured. Find the highest stress that can be
applied in any layer of the system without puncture and the highest stress that the system will
withstand even if there is a break in any layer.
