Investigation of power factor on harmonic effect due to types of voltage source
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper discussed about power factor on harmonic effect due to types of voltage source. Usually, the voltage source is sinusoidal. But in actually, the condition of the load is has voltage sources through the elements ...
Clear sky global solar irradiance on tilt angles of photovoltaic module in Perlis, Northern Malaysia
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-21)
The performance of a photovoltaic (PV) is highly influenced by its orientation and its tilt angle with the horizontal, due to the fact that both the orientation and tilt angle change the amount of solar radiation reaching ...
