Transformer derating with half-wave rectifier load
(Universiti Malaysia Perlis, 2008-05)
The deviation of the voltage and current waveform from sinusoidal is described in terms of the waveform distortion often expressed as harmonic distortion. The increasing use of nonlinear loads in industry is keeping harmonic ...
Transformer derating with full wave rectifier load
(Universiti Malaysia Perlis, 2008-05)
Transformers are basically passive devices for transforming voltage and current. Transformer allows voltage levels to be changed throughout the electrical distribution system. Transformers were simply derated to compensate ...
Development of minimizing the harmonic distortion and improving the power factor by using PFC FA5501 in 3 phase system
(Universiti Malaysia Perlis, 2008-03)
In this thesis, PFC FFA5501 is introducing to reduce the harmonic and increase the power system of the system. By designing the necessary technique and methodology, the overall Power Factor (PF) and the Total Harmonic ...
Effect of filter capacitor towards the input harmonics and power factor of single phase rectifier
(Universiti Malaysia Perlis, 2008-03)
Interest on harmonic problem is increasing due to increment of non linear loads such as
televisions, computers, monitors and others. These non linear loads contribute to low power factor (PF) and high total harmonic ...
Harmonic effect between VSI and CSI using PWM control scheme
(Universiti Malaysia Perlis, 2007-05)
The voltage source inverter (VSI) and current source inverter (CSI) are the type of inverters that commonly used today and mostly PWM (pulse width-modulation) drives. The functions of the inverters are for conversion from ...
Assessment of Harmonic Distortion in low distribution
(Universiti Malaysia Perlis, 2008-05)
In a power system, due to proliferation of power electronic equipment that produce harmonic current, harmonic resonance can occur when the system natural frequency closes or corresponds to the frequency of harmonic current ...
Effect of harmonics In laboratory equipments
(Universiti Malaysia Perlis, 2007-03)
This report, entitled “Effect of Harmonics in Laboratory Equipments” summarizes apart of final year project for the Electrical System engineering courses done in University Malaysia Perlis. This project is about learning ...
