Opis:
This work presents the design and analysis of percolation models for branches and nodes in networks created using electric circuits. Electric circuits were built using square networks consisting of appropriate resistance and impedance elements, as well as of power supply sources. The created percolation models were described mathematically, according to the Maxwell matrix method of cyclic current in the classical form and in the complex number form. Analytical descriptions of electric circuits include random methods of "short-circuiting" branches and creation of “filled” nodes, respectively, in the networks using appropriate calculation procedures in Mathcad. Simulation calculations of surface leakage current for a polymer sample were made using a model of its surface (percolation for a branch in the network) and a numerical program developed on the basis of calculation procedures contained in Mathcad. On the other hand, simulation calculations of power emitted on the surface of a cylindrical insulator performed using its surface model (percolation for nodes in the network) and a numerical program written in the Mathcad environment.

Opis:
This work presents simulation of calculations related to the value of leakage current amperage on a porcelain surface of a rod insulator performed using the percolation theory. Surface of a rod insulator has been presented in the percolation model for grid nodes. This model is an electric circuit which includes a resistance grid and a power (voltage) source. This model includes a randomised method of “filled” node creation within the grid. The procedure of simulation calculations of the leakage current amperage using the percolation model included creation of its equivalent circuit and declaration of appropriate current analysis in the PSpice program. Thus obtained values of leakage current on amperage the surface of a rod insulator were compared with values measured on insulators studied at the testing station. Similar values of leakage current amperage on surfaces of insulators were obtained in simulation calculations (for the percolation theory), and in actual measurements at the testing station.

electrical percolation models for branches and nodes of networks
Opis:
The paper presents the concept of creating and analysing electrical percolation models for branches and nodes of networks. These models have been formed with electrical circuits constituting regular networks (square, hybrid, hexagonal, and triangular), which consist of resistors (branches) and forcing voltage sources. These models include random manners of closing (destruction) of network structures of individual resistors as well as those properly grouped into nodes ‘filled’ on a square network. The random closing (destruction) of proper resistors in the enumerated percolation models was performed via shunting the resistors with contacts of respective contactors. The procedure of simulation calculation of currents (percolation) by means of developed electrical percolation models for branches and nodes relied on creating their replacement schemes and declaring adequate current analyses in the PSpice software.
