Current draw from an MIT Z Stablizer ll

Plug the cable into one of those Kill-A-Watt devices and see if any watts are being used.

Liz, it does not run hot.
Koestner-thanks,I'll get one.

Reducing power factor due to phase shift between voltage and current is one thing but don't forget that amps present itself as nonlinear load because of rectifiers. Current is delivered in narrow spikes of high amplitude repeated 120Hz. In frequency domain it represents a lot of energy in high harmonics of 60Hz. Power companies cannot effectively measure this (RMS much higher than Average Value) and it costs them money. On our side problem is different - narrow spikes of high amplitude create huge voltage drops and a lot of noise. Whole thing is one big noisy switcher operating at 120Hz. The best thing is to remove higher harmonics (noise) by filtering them out. Opening my Furman Elite PFi20 power conditioner reveals huge inductor and capacitor, basically a filter. Capacitor across the load outlet stores energy to deliver current pulses while inductor between this capacitor and mains removes upper harmonics (flattens spikes).

Thanks Kijanki. That's why I originally had a 'noise reducing & conditioning system' by MIT- that was very effective in its day. An isolater, a filter & power factor correction. Knowledge and technology has come a long way but noisy power is still a big problem.I find the new Shunyata technique of "separating the electrical and magnetic" portions of transmitted power very interesting. MIT was a leader years ago with their "parallel" noise reduction equipment; perhaps Shunyata new top tier equipment is ground breaking. I'm interested in the "Defender" as I assume Shunyata is bringing something "new" to the table. Parallel alone is not new. MIT and Enacom have been there a long time-and I still use those products to good effect-within bigger overall conditioning including an Equitech Q balanced transformer and top level MIT p/c's.
