    This paper presents the design and implementation of a Harmonic Current Compensator. Sources of harmonics, harmonic distortion, detrimental effects of harmonics and harmonic elimination methods are considered. Paper describes ...
  • Gunawardhana, WDDH; Jayaweera, MW; Kasturiarachchi, JC [Conference-Extended-Abstract]
    Ratmalana-Moratuwa industrial area has been subject to heavy pollution from various industries for more than a decade. This area is believed to have been polluted with heavy metals that have some drastic adverse impacts ...
  • Weerasundara, L; Vithanage, M; Ziyath, AM; Goonetilleke, A [Conference-Full-text]
    Atmospheric deposition is a serious issue in the context of biogeochemical cycling of heavy metals (HMs) and the resulting impacts on urban water resources. In this study, dry deposition (DD) and bulk deposition (BD) ...
  • Fernando, AKN; Perera, EMNS; Saranga, LS; Vijitha, AVP [Conference-Full-text]
    Kirinda fishery harbour is dredged out periodically to pump out sand to maintain its depth. Sand samples (n= 38) were collected from the dredged-out sand pile covering all the regions and were analysed for mineralogy, ...
  • Tasmia, F; Trina, NA; Rahman, MM [Conference-Full-text]
    Heritage must not only be a historic monument but also an active factor in contemporary life. The use of cultural heritage as a tool to respond to the rapidly changing socio-economic conditions becomes one of major focus ...
  • Vijay, M.A.; Shivangi, V. [Conference-Full-text]
    The densification of an urban core forces outward growth of the city to suburbs. The movement towards the suburbs is mostly residential for various reasons including economic, environmental or leisure. The sprawl creates ...
  • Samarasinghe, A.M; Jayasinghe, S [Conference-Full-text]
    The visual interpretations of railway interior in Sri Lanka continue to maintain its timeworn fashion only with minor changes while infrastructure and furniture design in the rest of the world, experience rapid transformation. ...
  • Paththamperuma, RS; Perera, I; Perera, K; Perera, C; De Silva, N; Javatunga, U [Conference-Abstract]
    Low voltage distribution network should be highly reliable with excellent security. For overhead feeders security is predominantly important. If an unrecognizable quantitative fault occurs at the overhead lines, the above ...
  • Karunadasa, JP; Bandara, IBH; Dayananda, WDD; Kumara, KGSU; Tennakoon, GMR [Conference-Full-text]
    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 ...
  • Priyadarshana, MST; Dissanayake, PBR [Conference-Full-text]
