Modeling of electrostatic fields at the environments with different characters leads to necessity of solution of the jump boundary value problems for the Laplacian in R3. The normal derivative jump problem at the Hilbert space the normal derivative elements of which have the jump through boundary surface was considered in (Nedelec, 1973). Solution of this problem was searched as simple layer potential. At the Hilbert space elements of which as their normal derivatives have the jump through boundary surface only normal derivative jump condition is not sufficient for obtaining of searched function. We have to add to this condition additional internal or external Neumann condition and suggest to look for the solution of this problem the sum of simple and double layer potentials (Polishchuk, 2003).
