I was wondering if anyone out there has a chart for residential demand based on either house square footage or kilowatt hours. I have a kwh to kw demand chart from Progress Energy, however this chart is from 1988 and the kwh only goes to 4000. I was looking for a more updated table possibly.
Had a field connection done wrong the other day and wanted some input on the scenario. It was a wye-wye bank.
Transformer # 1: H1=A, H2=N ===> X1=a, X2=n
Transformer # 2: H1=B, H2=N ===> X1=b, X2=n
Transformer # 3: H1=C, H2=N ===> X1=n, X2=c (Incorrect On Sec. Side)

I retrieved some recloser data yesterday for one of the feeders. The data was showing
Phase A: PF=0.95, kW=258, kvar=85, KVA=269
Phase B: PF=0.56, kW=237, kvar=-346, KVA=421
Phase C: PF=0.51, kW=213, kvar=-356, KVA=416
The power factor on b and c phases were of some concern, and was...
I am interning a a power company and a lineman turned in a sheet the other day on a transformer he was called out on. They replaced it with a 50 KVA and the readings were as follows: X1=182 Amps (Phase to Ground), X3=189 Amps (Phase To Ground). This transformer is a 120/240 single phase...
