As electrical professionals, you are constantly striving to improve uptime in your operations. However, the worry of unplanned downtime crippling your entire facility is always present. And oftentimes, the culprit behind most equipment failures is simply – harmful voltage fluctuation. The nightmares of expensive emergency repairs and high maintenance costs… Wouldn’t it be great if you could put an end to this problem?
Well, you absolutely can. But before you are able to solve this problem, you must first understand how voltage fluctuations occur. In this blog, we reveal to you the truth about dreaded voltage fluctuations and the most cost-effective ways to tackle this problem.
Let’s dive deep.
What is Voltage Fluctuation?
Voltage fluctuation refers to the rapid voltage changes or cyclic changes in voltage – where the magnitude of which does not normally exceed the specified voltage ranges. It can also be described as repetitive or random variations of the voltage envelope due to sudden changes in the real and reactive power drawn by a load. Let’s take a look at a typical voltage graph below to help you understand better.
This graph above shows a fluctuating voltage waveform.
It exhibits variations in magnitude due to the fluctuating nature of your connected loads.
Therefore, there are two important factors in Voltage Fluctuation – the frequency of fluctuation and the magnitude of fluctuation.
Both of these factors are significant in the negative effects of voltage fluctuations.
For instance, when arc furnaces or arc welding equipment are used, they commonly cause the voltage of your power distribution system to fluctuate – resulting in a negative operational impact on your equipment.
Why does Voltage Fluctuation happen?
To explain this simply, imagine yourself in a warm and relaxing shower after a long day of work, and someone turns on the hot water in the laundry downstairs…
Your hot paradise then immediately turns into an ice cold nightmare, and you are frustrated.
Voltage fluctuations are similar. It’s the electrical equivalent of water pressure and when it goes low, there ARE noticeable negative effects – both operationally and financially.
Voltage fluctuation is a continuous change in the voltage when devices or appliances that require a higher load – are extensively used.
So now that you have a deeper understanding about Voltage Fluctuations, you may be wondering – why exactly does it happen?
Let’s explore the details
Electrical consultants have proven that Australia has a huge problem when it comes to regulating electricity.
The AC Supply voltage ratings in Australia have been lowered. And with each passing year, electricity regulation is getting worse.
This results in various power quality problems such as voltage fluctuations in your electrical systems.
Harmful voltage anomalies can set your facility up for failure – causing a temporary malfunction in your electrical equipment, or in most extreme cases, an expensive and irreparable failure…
Leading to a drastic decrease in your electrical equipment’s lifespan, or even unplanned downtime (an engineer’s worst nightmare). So, in order to effectively tackle this problem, it is crucial to first understand the main reasons why it happens.
“Did you know? 85% of all voltage events originate within a facility. Voltage Fluctuations are caused by inadequate supply, undersized wiring, an overloaded circuit, and frequently by other equipment turning on or off on the same circuit.”
Here are the 4 biggest reasons why voltage fluctuation happens in your electrical supply:
So just how severe can voltage fluctuations be on your facility or electrical system?
Read on to find out.
Negative Effects of Voltage Fluctuations
The devastating consequences of voltage fluctuation can lead to the malfunction and destruction of your electrical machines and equipment…
Costing you a huge sum of money to replace your high value equipment. When the voltage applied is too high, it can cause several horrifying reactions in your electrical systems. And, if the voltage applied to the system is too low, it is possible that your electrical equipment cannot function at the expected load.
This causes the important parts in your equipment to get damaged because the current tends to increase in the circuit. Your wires might lose their general strength and this can cause a short circuit – leading to extreme fire hazards in your workplace.
So, here are 5 detrimental effects of Voltage Fluctuation that you absolutely need to be aware of:
Picture yourself in any of the above scenarios and you’ll know how frustrating it can get.
Flickering lights, customers or shareholders complaining because of the delay in production, equipment failure, or even worse… Total power failure in your facility.
Imagine how expensive it would be to fix all these problems. How can you stop yourself from being in that situation?
As the saying goes, prevention is better than cure.
So can you prevent something like this from happening? Let’s read on to find out…
How Can I Check and Reduce Voltage Fluctuations?

Stabilising Voltage Fluctuation with Ashley-Edison AVR Solutions:
Now, you may have heard about Automatic Voltage Regulators (AVR) as a practical and cost-effective solution to your voltage problems…
But what functions do they actually serve in your facility and how will they benefit you?
Automatic Voltage Regulators are preferred by many engineers to protect high value and mission-critical equipment.
These AVRs safeguard your facility equipment and sensitive electronics against harmful voltage anomalies – such as fluctuations and voltage surges that can cause permanent damage and reduce the lifespan of your equipment.
An Automatic Voltage Regulator (AVR) is a powerful voltage control equipment, designed to turn unstable incoming voltage into constant and reliable voltage supply – delivered straight to your load.
Here’s why an AVR is needed to completely crush harmful voltage fluctuations:
If the voltage at the load end is not maintained at a constant fixed rate, your equipment’s operational performance can be negatively affected.
And you don’t want that to happen because…
Your electrical equipment and machinery will suffer from an unregulated and unstable incoming voltage supply – risking unplanned downtime in your facility.
And because these AVRs are used to automatically regulate your voltage supply…
The incoming voltage supply will be corrected to your desired set output voltage level – almost instantly.
How Does An Automatic Voltage Regulator Work?
Put simply, the AVR continuously takes low or high input voltage ranges, and effectively compensates for the voltage fluctuations, with the additional benefit of maintaining a balanced, constant output voltage to your load.
An efficient AVR directly relates to the performance and longevity of your equipment.
This effectively ensures that your voltage output delivered to your equipment is clean and consistent in its load current – even if voltage problems occur in the background.
