In article the method, allowing to use possibility of a neural(neuronic) network for forecasting of tax base of region is offered. The given method is suitable for working out of the positive shortterm forecast.

The article discusses the issues of identifying the asymmetry of currents in a three-phase alternating current system. The design of a current converter designed to detect the unevenness of the current load in parallel branches of the current lines of various power equipment is proposed. It is shown that a positive effect is achieved by making the magnetic circuit four-rod and the introduction of rectangular cutouts with modulating and output windings on two central rods of the magnetic circuit and it is possible to determine the unevenness of the current load of three parallel branches before (in three-phase AC circuits) or after rectifier-converter installations (in DC circuits), therefore, the functionality of the device for detecting current asymmetry is expanded.
