In a portable generator.
Does one type of load vs the other make it more difficult for a typical
portable generator to maintain constant voltage?
Esp at a current approaching the continuous current limit of the generator.
I ask bec the mfr claims 1-2% regulation. *A small miller welder is causing
12%+ variation, within the current limitations, with the voltage variation
being fairly proportional to load. *I'm assuming a transformer load is
substantially inductive?
* *I haven't yet tested it with purely resistive loads, *cuz, *well,
*PURELY resistive? **Where in the heck would you find a PURELY
RESISTIVE
*load?
Oh, Attenuators. I didn't know that. *I guess that part of the circuit
is purely resistive or resistive/inductive.
(I just looked up "purely resistive")
An electric heating element, like a range element, toaster,
heater without a fan, water heater, light bulb etc are examples.
They all have some theoretical small inductance, capacitance,
too, but it's so tiny it can be ignored. *The voltage and current
through those devices is in phase.
I mean, you know. To be technical, in DC/AC/Grounding in electrician
school, they teach you that nothing is "purely resistive"
