Comparison on losses and flux distribution between two 3-phase distribution transformers 1000kVA assembled with air gap and without air gap of transformer core lamination
(Institute of Electrical and Electronics Engineering (IEEE), 2007-12-06)
This paper describes the result of an investigation on the effect of air gap of core lamination in two 3-phase distribution transformers 1000kVA. The investigation involves the variation of power loss, building factor, the ...
Tracing generators' output in transmission open access
(Institute of Electrical and Electronics Engineering (IEEE), 2007-12)
Over the past few years, the electric power utility industries around the world have experienced a strong drive towards deregulation. Based on the experience of deregulation of the communication, natural gas and airline ...
Power quality and electromagnetic compatibility -The 'simple or not so simple' ubiquitous power supply input stage -
(Institute of Electrical and Electronics Engineering (IEEE), 2008-12-01)
Power Quality is per se the ac line input voltage quality that in turn is determined by the interaction of the source impedance and the line current. Low frequency line current harmonics up to the 40th harmonic (2 kHz for ...
State space averaging technique of power converter with digital PID controller
(Institute of Electrical and Electronics Engineering (IEEE), 2009-01-23)
This paper describes a digital Proportional-Integral-Derivative (PID) controller technique applied to the DC-DC buck converter. The converter is modelled using a state spaceaveraging technique. Due to the non-linear of the ...
