Electrical Drive An electric drive is a system that converts electrical energy into mechanical energy. It also provides electrical control of the whole process through several devices and technologies (Figure 1). The objective is to create a smooth and versatile control to achieve a specifi c speed-torque characteristic. It is a key component of the power conversion chain between power sources ...

An electrical plan drawing–sometimes called a wiring diagram or drawing–consists of lines and symbols. Electrical drawings are prepared on 2D architectural floor plans using Computer-Aided Design and/or Drafting (CAD) programs. The placement/drawing power symbols–such as sockets, lights, switches–is the first step an drawing. For this purpose, smart system has been developed in study to automat...

In this paper two dimensional wave propagation is used for power combining in drain nodes of a distributed amplifier (DA). The proposed two dimensional DA uses an electrical funnel to add the currents of drain nodes. The proposed structure is modified due to gate lines considerations. Total gain improvement is achieved by engineering the characteristic impedance of gate lines and also make appr...

This study presents analysis of pico-hydro electrical power plant in North Sulawesi, Indonesia. The objective of this study is to get a design of axial turbine pico-hydro electrical power plant. The method used the study of literature, survey the construction site of the power plant and the characteristics of the location being a place of study, analysis of hydropower ability and analyzing cost...

Although electrical energy is one of the best and cleanest energy sources, the proper protection and utilization of it, always and everywhere is problematic. One of the most important problems is electric shock and the dangers that can sometimes be lost in the lives of people. When a body or part of it is completely located in a strong power supply field or a contact with a device that is conne...

In order to evaluate social benefits in electrical power inspection scientifically and assess social responsibility performance of power supply enterprises roundly and rationally, social benefits evaluation system of electrical power inspection based on FAHP was constructed in this study. Firstly, social benefits evaluation index system of electrical power inspection was established based on it...
