Power factor, simply put, is the ratio of working power to apparent power, or demand power. Power factor is an expression of energy efficiency, with a higher percentage indicating more efficient power usage and a lower percentage indicating less efficient power usage. To calculate power factor, divide working power (kW) by apparent …

Why Transport in Sri Lanka Continues to Go from Bad to Worse 99 was very resistant to change and incapable of catering to the growing demand. As a result, the open economy saw a huge demand for private vehicles which put pressure on road-building, especially in urban areas. Private investment was allowed for bus transport and

The study findings show that the poor ability of reading, understanding, speaking and writing amongst labourers resulted in poor labour performance in the construction work environment in Sri Lanka. This has been a major barrier for the labourers to take on challenges and opportunities in their work environment.

[Generation Performance in Sri Lanka] 2015 (First Half) 1 | P a g e 1. Introduction During the first half of year 2015, maximum recorded electricity demand in Sri Lanka was 2210.4MW (excluding the contribution of SPP Mini Hydro, Solar and Biomass) which is a higher value compared to the maximum demand of 2151.7MW in year 2014.

An electrical system with a low power factor is typically less effective and may also be less profitable for end users and system operators. Therefore, power factor correction is essential for effective system performance and for lowering the cost of electricity. This paper presents a study on the technical and financial benefits of power ...

Then At the unity power factor, the Full load current would be 20,000/250*1 = 80A. Whereas at a low power factor (say 0.8), the Full load current will be = 20000/250*0.8 = 100A. Here from the above example, it is clear that if a motor works at a poor power factor of 0.8 then it draws more line current than at unity power factor.

This policy brief addresses empowerment of rural farmers as a strategy to reduce poverty in Sri Lanka. Although Farmers' Organizations have helped improve rural life, capacity gaps and social environmental challenges remain. To this end, the brief suggests that bolstering investment in irrigation, assessing and empowering Farmers ...
