LV consumers are encouraged to invest on roof top solar and wind turbines to reduce the
stress on the utility side. Due to the intermittent nature of these distributed generators the
stability of the power system and the ...
With the current increasing trend for the non-conventional renewable energy (NCRE) in Sri Lanka, interest has been focused on retiring of thermal/coal power plants and getting the energy via renewable sources.
Since almost ...

Conveyor belt-type checkweigher machines are important part of modern production factories. They are used to determine the weight of the different types of products without stopping the products on the weighing conveyor. ...
Abstract
The phenomenon of magnetic hysteresis effect of the core material of a transformer plays an important role when representing the transformer in a simulated environment.
Input-output behavior of a transformer is ...
Proliferation of solar photovoltaics (PV) in low-voltage (LV) distribution networks
is inciting technical challenges in network design and operation with regard to the
quality of power. Violations of operational performance ...
umans interact with machines extensively through our auditory and visual
senses, but they frequently ignore their most trusted sense: touch. However, the sense
of touch has tremendous potential in almost all fields, ...
Hydropower is an extremely valuable resource. There are two types of reservoir based
hydropower stations with different main goals. Some are following the demand of the utility
