Reliability and stability of a power system get decrease with the integration of large proportion of renewable energy. Renewable sources such as solar and wind are highly intermittent, and it is difficult to maintain system ...

High Voltage insulators are vital components in transmission and distribution systems in a power network. Most of the insulators are used in open air applications where they are subjected to different environmental ...

In developing countries, small vehicles such as three-wheelers are one of the most commonly used public transportation method and considered as an efficient way to travel in the traffic. Even though the commonly used type ...

Current power system interest is intensely going towards the renewable energy integration to the system in the form of microgrids. Since microgrid has two major operating modes as stand-alone and grid-connected, cause ...

Trends on utilizing distributed renewable resources around the world have significantly increased the number of grid connected solar photovoltaic systems in low voltage networks. In Sri Lanka, low voltage systems are ...

This paper studies the use of insulating barriers on the breakdown voltage of oil gaps upon two type of coconut oils under AC voltage. A point plane electrode arrangement connected to a AC transformer is used to find ...

This paper presents mathematical modeling, implementation and experimentation results of Extended Kalman filter (EKF) implemented on existing flight control algorithm which is used to control multi-rotor unmanned ...

Regenerative AC-AC converters are required for serving AC loads that draw and return power during operation, when input is also taken from an AC source. AC motor drives, static VAR compensators, harmonic compensators ...

An accurate understanding of power transformer high frequency behavior is very important to assess the impacts on power system due to transient over-voltage conditions. An improved method of modeling power transformer ...
