Calculations for LV and HV networks

This Cahier Technique publication is intended to provide a general overview of the main electrotechnical calculations carried out in engineering studies on electrical systems at all voltage levels. It is complementary to other Cahier Technique publications that deal more with the operation of devices and installations in electrical systems. This document will help owners, designers and operators understand the importance of these calculations in ensuring correct use of the electrical network and their impact on the total cost of ownership.
