Good Practices for the Energy Transition


When choosing the conductor material for a busbar, the life-cycle cost of the system must be taken into account

In energy systems, life-cycle cost can be substantially larger than the initial purchase cost. When selecting an energy-efficient solution, the lifetime energy bill can be substantially reduced. Efficient systems run also cooler hence safer and with lower maintenance cost. These non-energy benefits are difficult to quantify but can outweigh energy cost savings and cut payback time in half.


A copper busway will be smaller and/or more efficient than its aluminium counterpart.

Compared to other metals, copper has the best (volume) conductivity (with the exception of silver). Therefore, for a given space, it will conduct electricity most efficiently, saving energy in the process. Or for the same efficiency, copper will save space, hence saving on other materials such as insulation, silicon steels, etc. The former effect will be about 40% savings, the latter typically about 20%.


The use of copper for electric busways is recommended when non-linear loads are to be expected.


A calculation of the life-cycle cost should also take into account the scrap value of the material at the system's en...


High-efficiency power transformers should be regarded as potentially large sources of energy savings.


Knowing the load profile for a power transformer is crucial to know whether to minimize the load losses or the no-loa...


Due consideration should be given to harmonic currents in power transformers.
