Since producing our first steam turbine in 1959, Fuji Electric has manufactured more than 464 steam turbines having a total combined output capacity that exceeds 23,619 MW, and has delivered these turbines to various countries throughout the world. In the industrial sector, Fuji Electric shipped Japan's first supercritical, pure transformation plant in 1973, achieving higher operating efficienc...

This paper presents the development of a force control loop in a teleoperation system with master and slave robotic devices. The force control based on current control loop has been applied to a teleoperation open platform consisting on electric master device, hydraulic slave robot and equipment for data acquisition and control programming. This force control loop is applied in each master join...

In order to protect wiring, facilities, human bodies and the like from electric accidents such as overcurrent to the load, a short circuit, ground fault or earth leakage of an electrical line, low-voltage circuit breakers, as typifi ed by molded case circuit breakers (MCCB) and earth leakage circuit breakers (ELCB), are installed in every type of machine, equipment, facility and building that u...

Some aspects are illustrated of energy conversion processes during the operation of electric railway vehicles with traction induction motors, in order to support transport systems’ sustainability. Increasing efforts are being expended to enhance the sustainability of transportation technologies and systems. Since electric drive systems are used with variable voltage variable frequency (VVVF) in...

This is a collection of reports that consists of three parts. The author is a Professor of Power Electrical Engineering, so he focuses on the Tu-154M power electric system and all aspects of the air crash that relate to electrical equipment and wiring. Part I discusses the electric power system of the Tu-154M. After brief introduction to aircraft electric power systems, the results of reverse d...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

The aim of this work was to determine the composition of the fish assemblage of Passa Cinco stream and verify changes in their structure on the altitudinal gradient. Six samples were performed at five different sites in Passa Cinco stream (from the headwater, at order two, to its mouth, at order six), using an electric fishery equipment and gill nets in May, July, September and November of 2005...

For protection against electric shock in electrical equipment, particularly control or instrument installations substation a quality earthing system is required. The also affected by soil resistivity with different types. In the equipment grounding system, knowledge of types electrodes and type At Prabumulih substation, Podzolic required to evaluate stress distribution that happens order reduce...
