Why Is My Generator Surging? Reasons You Need To Know!

When a generator surges, it makes it harder to operate and dangerous. In this article, I’ll go over a question: Why Is My Generator Surging? how you can resolve the issue with your generator, and how to prevent your generator from surging.

A generator is a machine that creates electricity. It does this through the use of rotating elements called “alternators.” Various factors could cause the electrical output to go above or below the rated value. For example, gearing, load changes, or dynamics in the power grid can cause this.

Why Is My Generator Surging?

The most common cause of generator surging is the improper voltage regulator. When this happens, the generator will cycle on and off rapidly, causing a surge in power. 

Surging can be very dangerous because it puts stress on electrical equipment and can damage it. It can also create instability in your power supply, which causes more problems.

What Is Surging?

Surging is a condition where the voltage of a generator or power supply varies up and down in a regular pattern. It is most often caused by problems with the generator or power supply itself, but it can also be caused by problems with other items that are connected to the generator.

Surging can be very dangerous because it puts stress on electrical equipment and can damage it. It can also create instability in your power supply, which causes more problems.

There are two main types of surge:

Electromagnetic surge – this type of surge is created when lightning strikes near your home or business, causing voltage spikes in your system. This surge damages sensitive electronic equipment like computers, televisions, stereos, and refrigerators.

Surge suppressor – this device helps protect against electromagnetic surges by regulating the amount of current that flows through an outlet, depending on how much electricity is being drawn from the outlet at any given time.

What Causes A Generator To Surge?

A surge occurs when there is a sudden increase in voltage on an electrical line. This can lead to fluctuations in current flow through the wire, causing it to overheat and burn out. If your generator is surging, its output voltage has increased beyond its normal operating range.

 I have listed some main causes of generator surging below.

Old Age The most common cause of a generator surging is old age. As a generator ages, the internal components wear out and become less efficient. This can cause the generator to overheat, which can lead to surging.
Fuel Problems Another cause of surging is dirty fuel. When fuel burns, it creates carbon deposits in the engine that clog up the valves and pistons. This causes poor performance and surging.
MaintenancePoor maintenance can also lead to surging. Overfilling your tank or letting it run dry can damage the engine, as well as failing to perform regular tune-ups on your generator.
Components with damage.A generator surge is usually caused by a problem with your generator’s components like fuel system, carburetor, ignition system and electrical components. These components are vital for your generator to run smoothly and efficiently. If any of these components are damaged, then it will result in an unstable operation of your generator which can cause it to surge at random times.
Abrupt machinery start-up.Generators are designed to operate within certain parameters so abrupt start-ups can cause them to surge or even shut down altogether. This is because they need time to build up speed before they can produce stable output voltages and frequencies; otherwise they could damage themselves or other equipment connected to them
Unbalanced loadOne of the most common causes of a generator surging is an unbalanced load. If your generator has an unbalanced load, it will try to stabilize itself by increasing its RPMs (revolutions per minute). This can cause your generator to surge or even shut down if it is overloaded.

Several Indicators Of Generator Surging:

Generators are designed to run at a steady speed but sometimes surge. When a generator surges, it rapidly increases in rpm and returns to normal. 

A generator that surges can cause damage to the internal components of the generator, as well as other devices, such as the home’s electrical system or appliances.

  • There are several indicators of a generator surging:
  • The lights flicker when you turn on an appliance
  • The sound of the generator changes from a steady hum to a high-pitched whine
  • The voltage drops significantly when an appliance is turned on.
  • Why Is My Generator Revving Up And Down

Generator revving up and down is a common problem. Many different reasons, including a faulty fuel pump or a bad spark plug wire, can cause it.

If your generator makes a loud noise, it’s probably not charging. So the first thing you need to do is check if the engine is getting fuel. If there is no fuel, your generator will not start, let alone run properly.

If your generator has enough fuel, it’s time to troubleshoot the problem and find out what’s causing it to rev up and down.

The first step would be to check the spark plug wires on your generator and ensure they are in good condition with no fraying or corrosion. 

This could be why your generator keeps revving up and down, as these wires connect directly to the spark plugs in an internal combustion engine. 

If one of them has been damaged or worn out, it won’t be able to send enough voltage through for ignition purposes, which will cause problems with starting up and running smoothly once started.

Another thing that could cause this problem is if one of the fuel injectors has been clogged up with dirt or debris accumulated over time due to a lack of.

How To Fix A Surging Generator? 

This is often because of problems with the carburetor, which can be fixed with basic troubleshooting techniques and simple tools.

Here are some tips on how to fix a surging generator:

  • Check The Air Filter Every Month
  • Keep Your Fuel Tank Full
  • Inspect The Spark Plug And Clean It If Necessary
  • Check The Carburetor And Replace It If Necessary

Conclusion:

If you’re experiencing these surges and your generator is still under warranty, call the manufacturer or seller of your unit. They’ll likely have a tech look at it for you and either fix it on-site or send you parts to make the necessary repairs. 

It’s rare for a surge problem to be so severe that an entire replacement is necessary unless the generator is faulty. If this isn’t a warranty issue, then your next step will be to have it repaired by a licensed electrician.

FAQS

Why do we need an AVR?

The AVR partially balances the generator’s constant power output.

What is an AVR?

A voltage regulator known as an automatic voltage regulator (AVR) is installed on your alternator and monitors the power output of your generator.
