polyphase metering single phase CT - 10/04/07 08:16 AM
Hi,
Brief background:
We have a 1Mw 11Kv - 400V transformer for our site (customer owned) with the metering CTs on the HV ring main unit.
We have had a company in to make recomendations on how we can save money on our fuel bills.
They recently monitored our electricity supply and came up with a recomendation that we shift load from the phase 1 to phase 2 (which is slightly less loaded).
They recommend moving approximately 20Kw over which will save £1000/month.
I thought this sounded a bit odd but they said that the CTs are usually only installed on phase 1. Has anyone else heard of this, it seems a suspiciously easy way to save money? Surely CTs arent that expensive when our average demand is in excess of 400kW
Thanks
