In modern electric power industry, there are problems of increasing the capacity of transmission lines, flexible control of their modes and redistribution of power flux between parallel sections. One of the possible solutions is the replacement of a double-circuit AC transmission to DC and the use of substations based on voltage transducers. Parameters and functional properties of such direct current transmission are considered.

The expediency of the secondary use of spent batteries of electric car as stationary storage of energy. The proposed structural scheme of interaction between storage energy and power. The obtained expressions to calculate the savings on your energy bill for the year and over the life of the battery.

The article provides a theoretical justification of the maximum possible values of currents in the transformer windings of the balanced device, depending on the size, nature and mode of the three-phase load at its output. Three cases are considered: symmetrical load, asymmetric load with the same power factor in phases, asymmetric load with different power factor in phases and asymmetric load with different power factor and character in phases.

On the basis of experimental studies developed recommendations on the magnitude of the preliminary magnetic magnetization of turbine generators, carried out in the experiments of DC attenuation in the stator winding of stationary electrical machines, provided by the current industry standard in the CIS countries on the methods of experimental determination of electromagnetic parameters of synchronous generators.

The article presents an experimental model of the device for monitoring the state of the support insulators and determining the place of a single-phase earth fault (OZZ) in distribution networks with isolated neutral 6–35 kV. OZZ occurring up to 90% of all types of closures. After damage to the insulators should break the wire air line, which in turn may be a step voltage. Also Ozzie has a negative impact on the electrical system, which could lead to a decline in economic indicators. Therefore, it is necessary to accurately determine and quickly eliminate the earth fault. The purpose of the work is to develop a device capable of remotely determining the location of the OZZ by means of GSM.

In this article the method to solving the problem of estimating the influence on the accuracy of identification both of the metrological characteristics of the measuring instruments and of the measured values of the parameters of the regime is proposed. The method consists researching the marginal errors in the parameters of the model of the lines and transformators. The application of this method makes possible to determine the areas of regimes that are optimal for carrying out measurements, and also to formulate requirements for measuring instruments.

In article the method of control and repair insulation winding wires of electrical products. To monitor damaged areas of wire insulation are used measuring the defects as the primary Converter of defects used a discharge sensor. The basis for the repair is put we have developed electrophoretic composition and its electrodeposition on the defective sections of wire.

In case of reactive power range of the generating equipment reduction (hereinafter referred to as the Range), SO UPS registers a Range reduction factor, leading to financial impacts (fees) that stimulate to restore the original Range. At present, the reduction of the Range is estimated only for the characteristics of the equipment at its installed power. This approach provides opportunities to manipulate the generating equipment Range characteristics by, leading to Range reduction without fees. This situation require a new algorithm for determining a reduction Range developing exclude the possibility of Range reduction for all values of active power generation without fees for equipment owner

Enterprises and equipment owners around the world are facing tougher requirements for reliable power supply. At the same time, their equipment is aging and requires more maintenance and capital costs to maintain, not to mention improving the existing levels of service. Thus, Assets are the key to the commercial success of any company/enterprise. The purpose of the existence of assets is to perform the function of providing services and to bring benefits to the owners. Therefore, asset management has acquired critical importance in the range of organizational tasks, and many enterprises have created an asset management group that deals with their solution.
