Electrical substation

and Operations of 220/132KV Grid Substation Chronology: 2008 to 2012 Geographical Location: Karachi, Pakistan Organization: Hamdard University Karachi, Islamabad Campus, Pakistan Title of Position: Electrical Engineering Student CE 1.2 Project Background CE 1.2.1 Background of the Study Grid substation is particularly identified as the station for generation of power through the incoming transmission line. The substation is responsible for delivering electrical power via the feeders and the station

Advantages and Limitations of HVDC and HVAC Transmission System in the Environment. 1. Effect of Electric Fields The electric field generated by the HVDC transmission line is a mixture of electrostatic field created by the line voltage and the field of space charge because the charge generated by corona line. Study of environmental influence of the electric field around the HVDC transmission line is occur in Canada and Russia have shown that discomfort to people who usually felt under the HVAC transmission

determine customer’s voltage range. Some standards assume a variation of +10% or -10%. However, it is determined by the utility based on their circumstances. 　　 　　III. VOLTAGE REGULATION METHODS 　　 　　The concept of voltage regulation associated with the electrical distribution system is caused by the radial

INTRODUCTION Grounding or earthing explain the concept of connecting frame of electrical equipment (non-current carrying part) or some electrical part of the system (e.g. neutral point in a star of the system, one conductor of the secondary of a transformer) with the respect to the earth. In electrical engineering, ground or earth is the reference point in an electric circuit from which voltage is measured, a common path for electric current, or direct physical connection to the earth. Bear in mind

technical recruiter focusing on the recruitment of Electrical engineers for various core engineering companies on behalf of B3. CE 3.2 Background CE 3.2.1 B3 is located in Kolkata , West Bengal is a growing manpower consultancy which provides recruitment solution to various industries in India and overseas. The company provides various kinds of recruitment solutions to the industries such as, construction and infra-structure, cement steel, electrical and electronics, manufacturing

Model-Based Approach The model-based fault detection approach employs a mathematical model of the system under observation, by assuming that a fault in the system will lead to deterministic changes in the model parameters. The model-based approach relies on comparing the model outputs with the actual system outputs to generate a residual signal, and based upon the properties of the generated residual signal, potential fault conditions are identified and useful information is extracted (Ding 2008)

The Distributed is electrical power generation in small scale (usually 1MW to 50MW) near the load centre using either conventional techniques such as Diesel generators and micro turbines or using non-conventional techniques such as Photo-Voltaic, wind turbines and small hydro power. This modern concept of power system is very advantageous as it reduces the load on the grid, consumers get a reliable power of better quality, and consumers can supply surplus power to the grid and earn a considerable

“. . . high-intensity electromagnetic radiation generated by a nuclear blast high above the earth 's surface and held to disrupt electronic and electrical systems.” According to this definition, an EMP attack will disrupt and possibly destroy all electrical systems. Just take a second to think of all the structures Americans rely on that are electrical. Essentially everything. This is why an attack of this kind is so terrifying. The United States is a very advanced country in terms of technology
