Investigation the effect of secondary burden of current transformer (CT)
(Universiti Malaysia Perlis (UniMAP), 2011-05)
Current Transformers (CT’s) are instrument transformers that are used to supply a
reduced value of current to meters, protective relays, and other instruments. CT’s provide
isolation from the high voltage primary, permit ...
Study of single phase transformer inrush current
(Universiti Malaysia Perlis (UniMAP), 2011-05)
When a transformer is initially connected to a source of AC voltage, there may be a substantial surge of current through the primary winding called inrush current. This analogous to the inrush current exhibited by an ...
Power transformer magnetization under different frequency supply
(Universiti Malaysia Perlis (UniMAP), 2011-05)
Transformer is a vital link in a power system which has made possible the power
generated at low voltage to be stepped up to extra high voltages for transmission over
long distances and then transformed to low voltages ...
Single-phase transformer with symmetrical AC output
(Universiti Malaysia Perlis, 2008-05)
Loads connected to electricity supply systems may be broadly categorized as either linear or non-linear. Non-linear loads are any loads which draw current which is not sinusoidal. The transformer is one of the most common ...
Protections of transformers against short circuits
(Universiti Malaysia Perlis, 2007-05)
This research focused on the protection of transformer against short circuit. Transformers are important equipment in a power system. The transformer needs to be protected from short circuit, one of the similar faults in ...
The influence of unsymmetrical AC power input to the core loss of a single phase transformer
(School of Electrical Systems Engineering, 2007-04)
This final year project describes about the influence of unsymmetrical AC power input to the core loss of a single phase transformer. The unsymmetrical ac voltage is generated using unidirectional (half wave) ac voltage ...
Study of single phase transformer using QuickField and Epstein test
(Universiti Malaysia Perlis, 2008-05)
The rising generating cost of electric energy and power losses has resulted in
utilities company requiring manufactures to build more efficient transformer. Therefore,
energy efficient transformer will reduce cost and ...
