That's simply incorrect. Our voice "peaks" are very long, compared to the RF frequency, they they have do indeed have a running RMS value. "Peak" on a watt meter is the peak power, which is always part of a a running-RMS (like a running mean but RMS instead) power.?

Your house current id 60 Hz and has a peak voltage of about 169 V. Is your light blulb or power input to you amp rated based on 120 VAC or 169 V peak AC? Yes, wire insulation must be rated for the peak voltage it is to with stand, but it's current carrying capacity is rated in the RMS current. There is no such thing as "RMS power": it's simply power, computed based on the RMS voltage, current, or the RMS voltage squared over the impedance, or the RMS current squared milipaited by the impedance.

Well our RF wattmeter usually has peak and avg selections ?? RMS is converting the AC to a DC value that is constant to

determine the constant heat W emitted. At a peak time snapshot , peak power and peak voltage are true for that moment.

Think of it like shoveling coal into a boiler. The heat produced is determined by the average coal added? time rather than peak

coal added in a moment.

So 'peak RMS values ' does not make sense, as once converted to rms there are no peaks nor valleys for the math purpose.

I can’t help but chime in: RMS is the only value that makes sense. Outlet voltage in your house is 120 V RMS. There’s no such thing as “RMS power”; peak power come from peak RMS values.?

Duty cycle is considered. These are peak voltage obtained by 100% duty cycle continues wave.

the Eimac formula for calculating grid dissipation is based on peak.?

anyway, anything I state is like I said, this is what I know, how I calculate it. I’m not an engineer, just an amateur. There are plenty of engineers floating around here and if I’m incorrect, I would love to be corrected as that would benefit myself and I’m always open to learning more. Any day I can learn is a day of victory.
