A practical field study has been carried out with the intention to analyze and compare the performance of various types of commercially available solar panels under Malaysia's weather. Four different types of solar panels, such as mono-crystalline silicon, multi-crystalline silicon, amorphous...

An empirical expression developed to estimate global solar radiation in clear days, on inclined surfaces located at any geographical position, is presented. This expression allows determining the global solar radiation in a specific day of the year, considering the attenuation of radiation in...

In the growing electricity supply industry and open access market for electricity worldwide, renewable sources are getting added into the grid system. This affects the grid power quality. To assess the impact on grid due to wind energy integration, the knowledge of electrical characteristic of...

This Discussion Paper analyzes the implementation of underground networks and their impacts on the energy and telecommunications sectors, through the main benefits, lessons learned regarding international benchmarking and an economic-financial analysis. The implementation of underground...

The recent ban on conventional incandescent lamps for residential use led Brazilian consumers to choose from three main lighting technologies: incandescent halogen, CFL (Compact Fluorescent Lamp), and LED (Light Emitting Diode). Despite the fact that their electrical performances are well known,...

This paper proposes a reduced 2nd, 3rd, 5th and 7th harmonic current of all power supply units and ac drives which effects of heating neutral cables and transformer. The commercial or automation building require the operation of many parallel-connected switch mode power supply and ac drive on...
