I have got a generator (Generac BSP7500LE) connected to my house (Via a
proper transfer switch!)

When running from this generator, there is a very noticeable flicker on
the
lights all the time.

I have a tester, and it tells me the voltage is 230v and 49.8Hz when the
generator is loaded at about 10A - what am I getting this flickering on
the
lights, and can I do anything to stop it!?

I have the same phenomenon with filament bulbs running off my 6KVA 2 pole
generator (3000rpm). Its because the generators speed is not actually
constant due to there only being a power stroke every 4 revolutions of the
crank and the lack of adequate inertia in the rotating mass to maintain the
speed- thus you;re not getting a proper sinusoidal waveform.

1500rpm (4 pole) or 960 rpm (6 pole) alternators or even the new crop of
inverter-generators dont generate this flicker.


I have three UPS' on various computer equipment, and they seem happy with
the generator's supply.

Mine doesnt want to know. Its a Belkin . Dont know why, the supply volts
& hz are within tolerance on the box. Any ideas?
