Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
The quality of electrical power in a network is a major concern which has to be examined with caution in order to achieve a reliable electrical power system network. Reactive power compensation is a means for realising the goal of a qualitative and reliable electrical power system. This paper made a comparative review of reactive power compensation technologies; the devices reviewed include Synchronous...
Paper deals with evaluation of chosen properties of newly developed modification of insulation material, composite based on glass-mica-epoxy material. The main reason for this analysis was to optimize the specific design of material. For improving some of mechanical and electrical properties the currently used material was modified by incorporation of nonvowen nanolayers into its structure before...
Presently the industry in Poland is more energy consuming than that of the most developed European countries (EU-15). According to the last available data from the European Commission (2010), the intensity ratio for Poland is almost twice as much as average in Europe. Thus, it is inevitable to set up an efficient strategy that will solve that complex problem and will be directly referenced to the...
The study compares power losses in the construction parts of the cold crucible (inductor, load and segments). The aim of the study is to determine optimum ratio between rectangle segment sides of the cold crucible considering power losses in the segments and load. For the numerical simulation the multi-physic software ANSYS was used.
This paper describes a software for creating models of energy flow and calculation the heating plan with use of the air/water heat pump. This model is used for specific buildings related to exact outdoor temperature calculated from previous years in specific locality. The software can be also used for exact heat pump design for the specific building. With appropriate plan, which the article deals...
The paper describes the results obtained from experimental operation of the arc heater with intensively blasted electric arc. The device has been designed for investigation of decomposition of stable harmful substances and later its construction has been modified to achieve steady operation with low gas flow rates. The modification consists in reduction the anode channel diameter with a solid cylinder...
This paper deals with a description and partial analysis of energy production units and their implementation in the laboratories of ENET technological centre in Ostrava - Vitkovice. The paper refers to individual types of conventional and non-traditional sources of electric power that are connected to the technological centre distribution grid, together with analysis of their topological configuration,...
Maintenance factor of lighting system is hot topic in the lighting engineering. At the present is still not solved the question about used luminaires and degradation of materials in time from which consist the body of luminaire. Maintenance factor as parameter for practical maintenance of lighting system is very important aspect for design of lighting system from the level of the project to real installation...
Article describes the design of lighting in growth chamber with low energy consumption. For this purpose we created a special luminaire that allows during different phases of plant life, regulate the spectrum of emitted energy and thereby effectively utilize light without wasting electricity. It is also important light intensity for proper growth of plants, respectively incident radiation. The paper...
Measurements of the instantaneous amplitude and phase angle of the fundamental current or voltage components and frequency that may be needed in three-phase power grid instrumentations/meters and relays may be affected by several encountering disturbances. These disturbances may be due to an abrupt heavy load changes and post-faults resulting in frequency deviation, DC offsets decaying, and harmonics...
