This study by Egemin explores and quantifies the relationship between cable sizing in non-residential electrical installations and energy savings. Such savings can justify larger cross sections up to a point. A trade-off between additional investment and operational savings is to be made.
The analysis follows these steps:
The main finding is that, under the current cable sizing practice, average losses in non-residential buildings range 2%. This value could be reduced to about 0.7% (i.e. a reduction of losses by 60%) under economic conditions by simply upsizing the conductor sections there where it makes economic sense in a 10 years perspective (considering both extra investment and avoided cost of losses).Log in to post comments
