The design and measurements results of power generator for ultrasonic compressor has been presented. The power regulator and the frequency adjustment unit was implemented in this project.
The study summarises the results of experimental examination of velocity sensing capability in a prototype of a magnetorheological damper with power generation (MRD). The device has two main components: an electromagnetic power generator and an MR damper. The study outlines the structure of the device with the main focus on the generator part, and provides results of tests performed under the idle run. The discussion of demonstrates the potentials of MRD action as a velocity-sign sensor and presents key issues which need to be addressed to enable its real life applications.
Catering trailers are small gastronomic points that sell food in unusual, remote locations where access to the power grid is difficult or impossible. Therefore, owners are forced to use a separate energy source to ensure continuity of operation of specialized equipment. The article presents the concept of a photovoltaic installation with an energy storage system in batteries, which is an alternative to traditional combustion generators. On the basis of the adopted assumptions, the daily demand for electricity in the trailer was determined, the elements of the installation were selected and a simple payback time was determined based on investment costs. The environmental aspects were indicated, as well.
Omówiono historię i dzień dzisiejszy firmy, która początkowo w ramach Energopomiaru, a obecnie jako samodzielna, wchodząca w skład Grupy Energopomiar wyspecjalizowała się nie tylko w pracach pomiarowych układów zabezpieczeń bloków i generatorów, ale której pracownicy czynnie uczestniczyli w konstruowaniu, budowie i montażu najbardziej nowoczesnych zabezpieczeń.
