WHATS CAUSE THE OUT PUT VOLTAGE FLACTUATED UP AND DOWN?

Question

1 MW PERKINS GENSET HAVE PROBLEM THATOUT PUT VOLTAGE IS NOT STABLE WHATS THE CAUSE?

Answer 1

Need more info could be a dirty carb or a dirty filter air or fuel could be air in the lines when the air bubble gets sucked through your set will bog out till it gets decent fuel through it.

But it could be a voltage regulator too,  in all honesty though its probably something simple loose throtle linkage filters dirty carb that sort of thing

if the engine is running stable Its on the electrical side if its not it could be one of the simple problems i pointed out

if its a gasoline engine (highly doubt in the case of a perkins)

you could check how the engine is running w a timming light.

if its diesel you might want to clean your injectors have you been running biodiesel that sort of thing

Answer 2

The following expressions are defined as used in this standard.

voltage fluctuation: A sudden and noticeable change in rms voltage level, usually caused by changing system loads.

voltage flicker: A repetitive voltage fluctuation that can cause irritation to people noticing the effects on equipment such as lights and televisions.
