Magnetization current waveforms and harmonic performance of single phase power transformer under DC bias
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
This paper presents an investigation of voltage-magnetizing current waveforms of single phase power transformer due to DC bias injection through simulation and experimental study. A method base on MATLAB simulation that ...
Investigate the power losses for transformer design on different material of CRGO (Grain Oriented Material)
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
The power loss will effect by the silicon contents on Grain Oriented Material. This will discuss about the core loss that occur in two different grain oriented material as M4 and M5 specimens. In this paper baby Epstein ...
Induction motor behavior due to symmetrical and un-symmetrical faults
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
This paper presents induction motor behavior caused by symmetrical and unsymmetrical
faults. PSCAD/EMTD power system simulation was used for a simple model and the investigation
purpose. Voltage sags are generally caused ...
Harmonic performance of single phase transformer with DC biased
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Direct current (DC) flowing through the earthed
neutrals of transformer windings causes a DC
component in magnetizing current. Owing to nonlinearity,
the waveform of this current is strongly
distorted. A high enough ...
Investigation of influence of voltage source type on harmonic characteristics
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
This paper discussed about influence of voltage source types on harmonic characteristics. Usually, the voltage source is sinusoidal. But in actually, the condition of the load is has voltage sources through the elements ...
