5 Generator AVR Failure Symptoms – Having a well-functioning generator is crucial to maintaining the stability of the power supply, especially in emergencies such as power outages.
That’s why you need to take care of the entire component of the generator well, one of them is the AVR (Automatic Voltage Regulator), which is responsible for regulating the output voltage. But how do we know if the AVR generator is damaged or not?
It could have been AVR damage and other components happening unknowingly. Wouldn’t it be dangerous if you just let one of the components of the generator be broken?

What are the 5 Generator AVR Failure Symptoms?

Ensuring that the AVR (Automatic Voltage Regulator) is in good condition is crucial so that you can use the generator for a long time.
If you feel that a generator does not work as it should while undergoing treatment then there are several ways to find out if the AVR is damaged or not. Try to learn the following ways.
1. Notice the Voltage Change
One of the first signs that the AVR generator is broken is that there is an unstable change in the output voltage.
If you see flashing lights or an electrical device working abnormally, this can be an indication of AVR failure.
For your safety and your family’s sake, it’s a good idea to use an electrical voltage gauge all the time while operating the generator.
Using the electrical gauge gauge allows you to notice whether the output voltage is already in line with the desired standard.
If the current voltage is unstable, turn off the generator immediately temporarily, then try turning it on again. If the power output is correct then you can return to using the generator as usual.
2. Check for Humidity and Physical Damage
If you see any signs of moisture, corrosion, or other physical damage on the AVR then this could be an indication of damage.
When this occurs, try to check and make sure that there are no broken cables or loose connections.
If the problem is found, just do a fix or replace the broken components immediately.
3. Compare it With a Well-Functioning AVR
If you feel that there is a possibility that an AVR is broken, you can try replacing it with a new AVR that still works well.
When the generator set returns to normal operation with the new one, it means that the previous AVR has already been broken.
AVR damage can only be dealt with by replacing a new component, so don’t wait to replace the AVR component when it’s time.
4. Ask to Professionals
If you are not sure whether the AVR is damaged or not, it is best to consult with an expert technician.
The technicians will definitely conduct a thorough inspection and carry out further tests to identify the problem on your generator as a whole.
They can also advise you on the steps you should take to fix it.
5. Do a Preventive Measurements
To prevent damage to the AVR and other components, perform preventive care on a regular basis, including cleaning off dirt and dust, checking connections, and checking the physical condition of the components.
Through good maintenance then you can extend the life of the AVR and keep the performance of the generator in optimal condition.

6 Cause of AVR Failures

But, has it ever come to your mind with anything that caused an AVR to be broken? Without knowing what caused it, it’s impossible you can handle it well.
Try to find out the causes of the damage below!
1. Overload
Electrical overloads occur when the generator is operated over its capacity. This often happens when too many electrical devices are connected to a generator at the same time.
Electrical overloads can put a heavy load on AVRs because they have to regulate the voltage on many electronic devices. This obviously can damage components in AVR and result in further damage.
2. Extreme Voltage Inconsistency
Sudden voltage fluctuations that increase or decrease excessively can damage the AVR.
When the voltage changes drastically, AVRs must work hard to keep the output voltage within safe limits.
Extreme fluctuation can cause an excessive workload on AVR and ultimately result in damage.
3. Your AVR is Already Passing Its Lifespan
All components have a limited lifespan, this including the AVRs. Long-term use of the generator can cause components in the AVR to fail.
If you do not perform maintenance on a regular basis, this can reduce AVR performance and reliability and result in total damage.
4. Humidity
Humid environments or contaminated by dust, dirt, and other chemicals can obviously damage electronic components in AVRs.
Moisture can cause corrosion that can ultimately interfere with AVR performance. That is why it is important to ensure that the generator is placed in a clean and dry environment to prevent this problems.
5. Installation Failure
Errors in the installation or connection of the AVR can also be the cause of the damage that occurs.
Loose connections, disconnected cables, or inappropriate installation will obviously significantly affect AVR performance.
6. Not Quality AVRs
Using AVRs of low or non-standard quality may increase the risk of damage. Low quality AVR may not be resistant to voltage fluctuations or heavy loads, so it is not surprising that damage occurs in a short time.

So there you have it! The 5 Signs of generator AVR Failure Symptoms!
In choosing the generators, make sure to look for the one with an SNI logo on it, as the generators with SNI logo on it, have been tested for its quality and safety.
The SNI itself is a product approval and certification to ensure that every product and service that are sold and distributed in Indonesia has already met the Indonesian standards and regulations.
Before being issued by the SNI certificate, those said products need to undergo a rigorous set of tests to determine its quality and safety aspect.
There are few items that are mandatory to be certified by the SNI certification as you can see HERE.
Other than that, the SNI certification also covers a lot of products in a lot of industries, ranging from automobiles to agriculture.
It is also recommended to put the SNI logo on your product aside from the mandatory list above.
So, as for business owners, having the SNI certification on your product can be so beneficial for your business.
The SNI certification can be used as a key selling point for your product, and it can also be used to boost the trust from the Indonesian market to your product.
