QUESTIONS ON OPTIMUM CONSTRUCTION OF DISTRIBUTED SYSTEM FOR MEASUREMENT OF ATMOSPHERIC ELECTRICITY

Atmospheric electricity as a matter is a difference of potentials between the Earth and ionosphere reaching up to 300 Kv. The actuality of research of atmospheric electricity, partially using ground distributed measuring network is noted. Studying this phenomenon, such events as thunderstorms, atmospheric aerosol pollution, radioactive pollution of air can be investigated and seismic activity before the earthquakes can be predicted. All above features prove importance and relevance of developing distributed networks for measuring atmospheric electricity and also methods for optimization of such networks and systems. The questions on optimum construction of distributed systems for measuring atmospheric electricity are analyzed. The major element of distributed network is an operational amplifier with resistive-capacity elements in the feedback contour. The task on information optimization of ground network of atmospheric electric field is formulated and solved. It is noted that research of atmospheric electricity using ground distributed measuring network is a vital and relevant task. The task on variation optimization is composed for solution of which additional limitation condition is applied which characterized general limitation condition imposed on total inertia caused by resistive- capacity contour. Taking this limitation condition into consideration, the task of non-conditional optimization task is composed, the solution of which makes it possible to formulate recommendations to achieve high informativity of measurements. The solution of variation task of optimization shows that this solution provides for a minimum of target functional. On this basis, the heuristic recommendation is developed in line with the real optimum solution should maximally differ from derived solution. As a practical recommendation it is suggested to use function which is inversion of derived optimum function.
