While owning a generator you can rest assured with plenty of power in case of emergencies or outages, taking a chill pill. But, the problem arises when your generator stops working up to the mark. Thankfully generators are quite talkative and give you the communicating signs if something wrong is going with them and maybe some sort of repair is needed.
What is surging?
Okay, first of all, what do we mean by the surge? The surge means to move suddenly or powerfully forward or upward, leading to fluctuations in the behavior of something. When talking of generators, surging is a phenomenon in which a machine(in this case generator) starts displaying fluctuations in its operation at certain intervals or in some cases even randomly, resulting in reduced efficiency of your generator.
Why is my generator surging?
There are several possible reasons for a generator to surge. One reason is that the engine is not running at a consistent speed. This can be caused by a problem with the governor or by a dirty air filter. Another reason is that the generator’s voltage regulator is not working properly.
Various signs of generator surging:
- Back and forth flickering of lights from getting too bright and then dimmer rapidly.
- The drastic changes in various components of the generator like the increase and decrease of speed of the fan for no distinct reason at all.
- Sudden shifts in the pace of the machine.
Here are other factors that cause generator surging:
Improper fuel use / Fuel Problems
Just like eating healthy food keeps you fit and healthy, in the same way, the generator requires a specific fuel as per its requirements so that it can perform with its full efficiency and also at its best level. Choosing the poor quality or wrong type of fuel is one of the biggest mistakes that you can do, which in the end will only leave you with regrets. As it is one of the main factors that cause operational problems and surges.
Poor Maintenance
Your vehicles need proper maintenance and repair from time to time so that it keeps on functioning properly, and if any problem is found out in its components it could be fixed immediately. The same is required in the case of generators. Every machine requires proper maintenance, otherwise, with time it will become a piece of junk and may start showing signs of surging. In order to stop your generator from getting rust, and falling into disrepair due to lack of use, it’s necessary to put it through paces monthly. Also, make sure that the machine is handled by professionals in case of repairs.
Old Age
Just as a human body starts deteriorating gradually with time, the same can happen in the case of machines, electrical or mechanical devices. The generator starts wearing out from the years of use, which obviously affects its efficiency and overall quality. Due to this, it can cause surges, since it has now lost the charm of its young days. In such a case, we would recommend you replace it if possible. You are tired of this old guy. Aren’t you?
Problem with components
Any damaged component which requires an immediate repair, but you are neglecting it, will clearly show the signs, which you won’t like to see of course, but which are good since that alerts you something is up with your generator and action is required. In some cases, there might be a damaged capacitor which can cause fluctuations, leading to the improper distribution in power supply and surges.
Frequently Asked Questions
Can a generator cause a power surge?
Yes, a generator can cause power surges. So, what causes a generator to surge? Due to various reasons like improper maintenance, wear and tear of your machine with time, component or capacitor problem, etc, can end up in power fluctuations or improper supply of power.
What does it mean when a generator is hunting?
In simple terms when a generator is hunting it means that you notice changes or variations in its speed or power supply after certain intervals or randomly. Sometimes it can get high and then suddenly turn down very low, leading to variation in the power output of your generator.
Why is my generator running rough?
One of the main reasons that cause rough operation of your generation is a clogged carburetor. When the fuel is left for a longer period in the generator, it causes certain ingredients in the fuel to evaporate, leaving a sort of sticky and thicker substance which clogs the carburetor. This slows down the engine which leads to a rough operation. So, make sure to clean the carburetor for the smooth functioning of your generator.
What is a surge arrester in a generator?
Many generators nowadays come with surge protectors which basically limit the amplitude of impulsive waves, protecting the generator insulation. Often over-voltage transients can occur on a conductor, and so the job of a surge arrestor is to protect your unit from such overloads, ensuring your safety.
How does a surge arrestor work?
In simple terms, a surge arrestor diverts the high voltage to the ground by minimizing the voltage through the Metal Oxide Varistor(MOV). It is a semiconductor that is highly sensitive to voltage and works as an insulator not allowing the electric current to pass through. When there is a standard AC voltage it works as an open switch and in case of high voltage or lightning as a closed one.

The bottom line is there are various reasons that can cause a generator to surge. If you are witnessing some, it’s time to contact professional electricians and seek proper guidance to deal with the issue.
