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 ...
Harmonic content as the indicator of transformer core saturation
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
The paper proposes a measurement method for obtaining the parameters needed to calculate a reliable indicator of the state of transformer core saturation. The major nonlinear effects in transformer core are saturation, ...
Current transformer reaction with linear and non-linear loads
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
The used of non-linear loads nowadays in industrial system has increased accordance
with the present technology. However, the used of non-linear loads supply more
harmonic distortion into the distribution systems. ...
Harmonic monitoring at UniMAP distributed campus
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-06)
This paper an attempt has been made to monitor and analyze the harmonic distortions caused by certain typical non linear loads of an educational institution. The current and voltage harmonic distortion at PCC feeding office ...
