Design resonant transformer
(Universiti Malaysia Perlis (UniMAP), 2011-06)
This project aims to design a resonant transformer. A resonant transformer is basically an electromagnetic static equipment based on the principle of Faraday’s law of electromagnetic induction that can be generate high ...
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 ...
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 ...
Simulation flux distribution and loss calculation of three phase transformer core 100kVA using FEM
(Universiti Malaysia Perlis, 2008-04)
This theses describes result of simulation flux distribution and loss calculation on
three phase transformer core 100kVA using FEM. From these theses, best material and best T-Joint configuration can be found. It’s important ...
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 ...
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 ...
11 kVA Substation design and commissioning
(Universiti Malaysia Perlis, 2008-05)
This report will explain about the final year project title as “ Designing and Commisioning the 11kV Electrical Substation”. In the part of designing this electrical substation, it need to localize and installation a several ...
