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 ...
Parameter determination of 0.5 hp induction motor based on load factor test - A case study
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-21)
The load can influence the efficiency of the induction motor. Even if the load has higher or less load factor, it can reduce the efficiency of an induction motor by several percentage. By knowing this, it is important that ...
Harmonic content as the indicator of transformer core saturation
