Response of induction motor to balance voltage sags and momentary interruption
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper presents result of experimental study of induction motor behavior when subjected to voltage sags and interruption. Small induction motors were used to investigate this phenomenon. A shaffner “Profline 2100” EMC ...
Induction motor behavior due to unsymmetrical and symmetrical faults
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Voltage sags are generally caused by faults on transmission and/or distribution systems. The voltage produced may be either unsymmetrical or symmetrical, depend on type of faults. Unsymmetrical fault is faults caused by ...
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 ...
Sensitivity of low voltage consumer equipment to voltage sags
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
Voltage sag is an issue that is becoming increasingly important to electricity consumers at all level of usage. These result from with increasing use of electronic equipment in several sectors for the reason to improve ...
Photovoltaic powered uninterruptible power supply using smart relay
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
Uninterruptible power supply (UPS) sits between a power supply such as wall outlet and devices to prevent undesired feature that can occur within the power source such as outages, sags, surges and bad harmonics from the ...
