Hi,

We(the building owner) dont have any metering CTs permanently installed so we just have the poco CT for their meter which is the only one that we get billed on.

I had wondered about the tx losses, it gets pleasently warm and people gather around it in winter for the warm draft!

Our loading is mainly 3 phase, large motors (90kw is the largest I spotted) a moderate server room, lots of discharge lighting some A/C and a couple hundred PCs. 50% of the load goes into our gas furnaces and cooling plant which is all motors and pumps.

We are hoping to save £100/month by moving 20kw over. This will probably be the single phase office consumer units which have about 20kw of electric heating so it should average out as the heaters cycle off and on.

Thanks smile
