Predicting an investigation of flux distribution in three phase induction motor stators by using different stator slot sizes
(Universiti Malaysia Perlis (UniMAP), 2010-09-16)
The predicting of different stator slot sizes on flux
distribution in three phase induction motor is
presented. For both stator models, the maximum flux
density is found near the tooth tip and minimum
towards the outer ...
An alternative approach to solar and grid-connected hybrid electricity for homes and buildings in Malaysia
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper presents the proposal of a solar and
grid-connected hybrid electricity system for homes and
also buildings. A new concept of using a DC motor
and synchronous generator as an electromechanical
inverter is ...
Current transformer reaction with total harmonic distortion
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Current transformer (CT) has a critical role in
protective and measurement devices used in both the
industrial and the utility worlds. However, the used of
current transformer in harmonic condition brings
some effects ...
The effect of different stator slot size on the stator copper loss
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
The input power to an induction motor is in the form of three phase electric voltages and currents. The first losses encountered in the machine are I2R losses in the stator winding. The stator copper loss occurs when the ...
Flux pattern in 1000 kVA 11/.433 kV distribution transformer core to sinusoidal wave
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
A study was conducted using sinusoidal waveform
to capture flux pattern in CRGO M5 material in a
1000kVA 11kV 3 phase transformer core. It is found
that it takes about 180⁰ electrical degree cycle for a
pool of flux ...
Investigation of power factor on harmonic effect due to types of voltage source
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper discussed about power factor on harmonic effect due to types of voltage source. Usually, the voltage source is sinusoidal. But in actually, the condition of the load is has voltage sources through the elements ...
Design of high-side MOSFET driver using discrete components for 24V operation
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
This paper presents the design of a high-side N-channel MOSFET driver using discrete components for 24Vdc operation. Special level shifting technique is used to increase the gate voltage higher than the supply voltage. ...
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. ...
Power losses test for electrical machine design on non-grain oriented different thickness material
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
This paper examines the effect of thickness in power loss for non-grain oriented material. In this paper, Epstein frame is optimized for both materials and the data is presented based on 50 Hz. The leakage flux is investigated ...
