The design of high-voltage distribution - or more correctly 'medium voltage' - is one of those areas that most practicing Senior Electrical Design Engineers should know about, but sadly never quite seems to make it onto HE college and university curriculum. With the result that many Engineers can relate to the terminology - 'CTs, RMUs, VCBs,' etc - but are not quite sure how to correctly design a practical distribution system at 11kV.
But knowledge in this area is all the more important today, especially as one of the biggest growth areas is the power sector - consider, for example, the proportion of high voltage design in relation to 'energy from waste' facilities or 'data-centre' work. Can your practice afford NOT to know?
This module aims to provide an excellent introduction to both 11kV and 33kV systems and takes you through:
the choice of distribution systems
the comparison of SF6 and vacuum circuit breakers
the required characteristics and necessary operation settings for the protection relays
The module also ensures that you will be understand how to achieve not only discrimination across an installation HV/LV transformer, but full discrimination throughout your distribution network, right back to the DNO supply.
