In this paper are proposed two ways of communication in the Off-Grid system, PowerLine communication (PLC) and wireless. Four concepts are created by combining ordinary or smart appliance and PLC or Wireless communication. Reliable communication is necessary for proper operation of the Off-Grid control system based on demand response. It is important for control system to know what appliances are connected and running and for an appliance is important to know whether it is allowed to start operation. At first, the Off-Grid and its control system is described, then several parameters of the communication network created by PLC in the Off-Grid system are tested and analysed. During testing, different appliances are connected to the Off-Grid to identify their impact on these parameters.

In this study features and factors important for thermal fields of several high-voltage electrical apparatus elements, such as high-voltage transformer input, polymer surge arrestor, bus contact and high-voltage power cable, have been considered. Stationary thermal field disturbances, caused by defects, have been studied, and possibility of their detection via monitoring data from infrared, contact and optical temperature sensors have been assumed. The features of non-stationary thermal field disturbances, taking place under pulse currents in bus connections and surge arrestors, have been analyzed, thus allowing to get information about device defects.

This article deals with electromagnetic field simulation of earthing switch for conditions met during short-circuit tests – withstand as well as making. The key issue to be solved is behavior of current path - mainly contact system from the electrodynamic forces point of view. Several configurations of current path geometry including current inlet were assessed. The second part of the paper deals with verification of simulations by real tests. During testing, special system for arc light intensity reduction has to be used together with high-speed camera so that the mechanical system behavior is clearly visible prior to moving and fixed parts touch (switching-on arc) and during current flow.

The present paper deals with applying of surge protective devices (SPD) for protection of air-insulated substation's low voltage networks. Key point in application of SPD in substation low-voltage networks is the estimation of lightning current distribution between the different communications of the object of interest. The measurement and calculation results of pulse current distribution between grounding and cable line at limitation of lightning strike in searchlight tower, combined with lightning rod, had been presented. Real-life field measurements have been conducted on training range of “Lenenergo” JSC. Value estimation of lightning current, flowing through SPD, installed on a light control switchboard, is given. The requirements for pulse current amplitude of SPDs have been defined. The general approaches to organizing substation light network protection from pulse overvoltage had been described.

In an era of the widespread introduction of information technology, the broadest possibilities are opening up for the implementation of additional services for prosumers in the electricity market. The traditional electric power system of Russia allows customers to receive electricity only from large power plants, which leads to centralization and monopoly. Currently, the concept of distributed generation is gaining popularity. The idea is that small electric power generators are distributed throughout the local power network. The introduction of such an electrical network will improve the reliability of the system. However, such a network needs effective management and an electricity metering system. This paper proposes the use of distributed network blockchain technology as a solution to these problems. The proposed double-chain blockchain model will provide for the electric energy trading within the local electricity market, without third-party intermediaries, with a sufficient level of security and automation for all participants.

The breakdown behavior of oil-barrier insulation is of special interest for design, manufacturing and quality testing for relevant insulations in electrical apparatus. Besides the commonly used mineral oil with different chemical structure (inhibitors) also other insulating fluids as natural and synthetic esters become more and more applied as an alternative ecofriendly fluid. The application in electrical power apparatus needs, at least, the same withstand ability against electrical breakdown as given by the well-known mineral oil properties. In practical design e.g. of power transformers very often interfaces of pressboard material are used mainly in form of insulating barriers. Therefore, the knowledge of breakdown properties of such type of insulation and, in particular, the interaction between the pressboard barrier and the insulating fluid seems to be obligatory for an optimal design of relevant apparatus. The paper deals with some results of breakdown behavior of oil-barrier insulation at inhomogeneous field under lightning impulse voltage stress conditions. The investigation was performed with various types of mineral oil as well as natural and synthetic esters. To provide inhomogeneous field conditions a test arrangement tip-to-semi-sphere was used. For having some reference values also the same test set without barrier (pure oil) was investigated. Additionally, some tests were carried out at standardized conditions (homogeneous field). For generalizing of measured voltage values the electrical breakdown field strength was evaluated. At pure oil test set (reference values) the known polarity effect was measured, what means, that at positive polarity (tip) the breakdown values are significantly lower than at negative one. That was valid for all tested oil types excluding the synthetic ester (FR 3), at which an opposite result was obtained. With pressboard insulation the charging effect of the barrier leads to significant higher electrical breakdown field strength, dependent on used fluid. When the barrier insulation was tested with mineral oil NYTRO BIO, the highest breakdown field strength of ∼ 300 kV/mm was obtained (negative polarity). The measured polarity effect for the tested fluids was not so unambiguously as for reference values e.g. so for NYNAS TAURUS, LYRA and FR 3 lower breakdown values have been measured at negative polarity. Also the impact of surface charge on the barrier to the breakdown process was studied by simulation and measurement. Generally, the surface charge on barrier increase the resulting electrical field strength and leads in the insulating gap between barrier and semi- sphere to a (quasi) homogeneous field. If the value of that field strength is high enough, the final breakdown will be initiated. Because of various discharge conditions for “uploading” the barrier under different polarities the mentioned polarity effect might be understandable. That effect should be further investigated. Nevertheless, any evid

This article deals with specific situations where lighting system meets standards, but there is a problem to see an object or whole scene visibility is low. We define specific problems that lead to these unsuitable optical conditions for the camera system. We meet environmental standards like energy efficiency and obtrusive light. This article gives some advices how to improve the design project. Several measurements have been made in no rain, snow or foggy conditions. Model with snow on surface is made, to find out if we need to measure it with snow on ground or not. Individual camera parameters have been analysed. Illuminance and luminance behaviour analysis was made.
