  • An over-current indica tor 
    Ranaweera, A; Chandanandana, D; De Silva, MTK; Hewawasam, HYA; Indika, K [Conference-Full-text]
    The over-current indicator indicates to the user that the current in a circuit is exceeding its rated value as soon as it occurs. The current is sensed by a current transformer (CT) and the rectified and regulated output ...
  • An experimental method to determine the thermal conductivity of concrete 
    Nanayakkara, SMA [Conference-Full-text]
    This paper reports an experimental method developed to measure the thermal conductivity of concrete. This method involves the measurement of steady state temperature distribution across a cylindrical specimen of concrete ...
  • An analysis of pelton turbines as related to mini-micro hydro applications 
    Fernando, MARV [Conference-Full-text]
    Large Pelton turbines used in major hydro applications are of high efficiency, in the range of 92% or more. However, Peltons used in mini-hydro applications in Sri Lanka were often found to be of lower efficiency, and of ...
