Induction motor efficiency test methods: a comparison of standards
Improved efficiency is the task of the hour. Environmental challenges, which include climate change, global warming and greenhouse gas emission have been fuelling the need to increase energy efficiency in electrical rotating ...
The effect of a reduced power quality on the energy efficiency of stand-alone generator systems
It has already been thoroughly validated that the efficiency of direct online motors is susceptible towards certain power quality parameters such as voltage unbalance or harmonic voltage distortion. It can be assumed that ...
Attenuation effect with non-linear loads for small stand-alone grids
This paper presents the effect of non-linear loads on the overall voltage quality in small powered stand-alone (islanded) systems. The iterative effect between current and voltage distortion is related to the source's ...
Evaluation of system losses due to harmonics in medium voltage distribution networks
Power system harmonics are a known cause to failure, disoperation or premature aging of customer's equipment. It also causes additional losses in a distribution network that influence the planning and design of future ...
Modeling and validation of losses due to unbalanced loading of stand-alone generators
The goal of this paper is to evaluate the possibility of deriving a simple lumped electrical model of the additional losses in stand-alone synchronous generators due to unbalanced loading. An in depth analysis will reveal ...
