Powering the Shard

Former Community Member

Afternoon one & all


I know we have single and three phase power, single mainly for domestic and three phase for commercial and small industrial.  But what sort of supply would The Shard have, does it have several 3 phase supplies or does it have an even higher supply that is then lowered via step down transformers to supply the various floors etc?

    A building of this size is not going to tap into the 415 V 3-phase local supply. It is going to have is own substation. And that substation will not be the source of the 415 V supply for the building. More likely the substation secondary will be something like 3·3 kV. This will supply 3·3 kV / 415 V transformers dotted around on various floors. If there is large machinery, this may be fed from the 3·3 kV.


    That's my guess anyway; there are various possibilities.


    I now await some bright spark with intimate knowledge of the Shard to tell us how it really is set up.
