The result of 5N from Besoeker blender appears to be too small to be correct.Besoeker; said:You are no doubt conversant with the definition of the Amp?re as the constant current that willproduce an attractive force of 2 ? 10^ -7 newton per metre of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one metre apart in a vacuum.
That gives us a starting point. Let’s assume that the fault current is 10kA. We have something under that from the supply in our test bay so maybe not an unreasonable assumption. How far apart are the MOVs? Say 20mm (about ? of an inch). Chuck those numbers into the Besoeker blender and you come up with a force of 5N.
