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 ...
Investigation of photovoltaic modules cooling system
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
It is well known that the power and efficiency of photovoltaic (PV) module usually falls at the rate of ~0.5%/°C and ~0.05%/°C respectively as increase of ambient temperature. The electrical efficiency of PV cell depends ...

The paper discusses the factors which determine the
losses of induction motor. The loss mechanisms are
described in this paper and it is related to the
performance and design characteristics of induction
motor such as ...
Epstein and iron loss test for Incoming Quality Assurance (IQA)
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Epstein test is well known method to test the specific total loss in magnetic material. Epstein test procedures are complicated as well as destructive test. Therefore, the Iron Loss Tester is an alternative test and can ...
Statistic data analysis of localized magnetic flux density and power loss
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
The experiment data were collected by using the search coil technique and temperature arise with time in order to measure the magnetic flux density and power loss. Statistic data analysis and engineering knowledge are tools ...
