| You are correct. That is why virtually all commercial customers
| of electric power utility companies with an electric service of greater
| than 200 amps are also metered for reactive kva (RKVA). Newer meters have
| dual indicators for both measurements within the same meter housing, and
| older power installations or those for large services use separate meter
| housings.

Hum.. Sounds like I might have a use for all those 5KVA Topaz transformers
I picked up.
