how many folks have +10kVA trannys before the rig?

Jeffcott,

No disrespect taken. My comments were mearly directed at trying to pass what I learned when experimenting with the small iso location.

WRT to the desirability of having an iso in the living environment, while the small iso is virtually inaudible and only slightly warm to the touch, the large iso can easily be heard from several feet away, and is quite warm to the touch. Hence, I decided to locate both isos on the block wall just outside the audio room.

I have been using balanced ISOs in my living environment for the past 5 years; currently 1 x 2kVA Equi=Tech Q type and 2 x 250VA in a single chassis. I recently completed a rebuild in a taller chassis, to add the second 250VA transformer. The large iso has an oversized core, is very immune to saturation from DC on the power line, and as a result, runs quietly. I've tried other isos that were very noisy.

It must cost you guys $50.00 plus a month just to turn these transformers on. I tryed a tranny from GE, just to power up the coils it pulled 5 amp for a 5KVA 208vac to 110vac stepdown center tap balanced transformer. I was told by GE that the amp draw is normal, too much cost for me. I even tryed to use a starter for on off cotrol but the breaker tripped on inrush at times.
I picked up a line reactor that I am going to try soon to clean up my power. They work on VFD's to stop dirty power for getting to it or from it.

I prefer real woman myself anyway. LOL.

Albert, if anybody can push the limits of 15KVA, it's you. Gas appliances?

Ngjockey, actually it's a 25KVA transformer but I didn't notice I typed the numeral wrong until later in the thread.

I'm the only one in the neighborhood on the service, so it's more than enough.

We have gas HVAC and gas water heater but in Texas the killer is summer heat and associated AC cost. I installed a commercial 3 phase AC (8 tons) and it really did help cut the electric bill.
