Benefits of Power Quality Monitoring in Industrial Settings

Michelle Kemp • March 13, 2025

In the commercial and industrial sectors, reliable and efficient electrical power systems are foundational for uninterrupted operations and long-term profitability. However, poor power quality caused by factors such as voltage sags, harmonic distortion, or power factor issues can result in equipment malfunctions, downtime, higher energy costs, and even safety hazards.


This is where power quality monitoring becomes indispensable for businesses. By implementing advanced monitoring systems, organisations can assess, and potentially improve the quality of electrical power delivered throughout their infrastructure.



In this post, we will explore the advantages of power quality monitoring for businesses, and how this can help improve reliability, optimise energy usage, prevent disruptions, and reduce operational costs.

What is Power Quality and Why Does it Matter?

Power quality refers to the standard of the electrical power supplied to equipment. Optimum power quality ensures stable voltage, frequency, and waveform to prevent disruptions. Any deviation in these parameters can negatively affect the performance of electrical equipment, leading to reduced operational efficiency, higher maintenance costs, and even shortened equipment lifespan.



In commercial and industrial contexts, such as data centres, manufacturing plants, and hospitals, maintaining a high standard of power quality is essential. Even small variations in voltage or transient events can cause substantial economic impact due to downtime, damaged equipment, or compliance failures.

    The Role of Power Quality Monitoring in Electrical Systems

Power quality monitoring involves using specialised tools and systems to measure and evaluate the performance of your power system. It provides real-time insights into critical metrics, such as voltage and current, harmonic levels, power factor, and reactive power. By performing a power quality analysis, Quality Energy can help businesses to identify and resolve issues before they escalate into costly problems.



Modern monitoring tools include network analysers, energy meters, and advanced software for harmonic analysis and fault identification. These tools collect and analyse large amounts of real-time data to help assess the performance of the electrical network. Additionally, they can detect anomalies and ensure compliance with international power quality standards, such as IEEE 519.

  • Enables early detection of power quality issues 
  • Ensures compliance with various standards and regulations related to power quality
  • Improves production efficiency by preventing disruptions in manufacturing processes
  • Lowers electricity bills by avoiding penalties and improving power factor
  • Contributes to reducing CO2 emissions by improving energy efficiency, aligning with corporate social responsibility goalsMinimises risk of damage to sensitive electronic equipment and machinery malfunctions from poor power factor or harmonics
  • Enables better load management and scheduling of heavy equipment use during off-peak timesReduces frequency of replacements and repairs, saving costs
  • Helps maintain a safe working environment by identifying potential electrical hazards
  • Allows for comparison of current operating parameters against manufacturer baselines

    Tools and Solutions to Monitor Power Quality

Companies with the right equipment can measure and analyse power quality effectively. That’s where the team at Quality Energy comes in. As part of our power quality audit service, we install power quality monitoring systems to determine exactly what corrective action is needed. This includes power quality analysers to measure and analyse voltage, current, waveform shapes, and harmonics and to provide insights into energy consumption.

After monitoring and evaluating the quality of your electrical systems, we may recommend custom made solutions, including:

    How Quality Energy Helped Optimise Power Systems Across Industries

  1. After reviewing data, Quality Energy designed, built, commissioned, delivered and installed power factor correction and active harmonic filter for this plastics manufacturer. The result was a reduction in total harmonic distortion from 19% to 3.5% and an improved power factor of 0.98.
  2. An aged care facility was experiencing voltage fluctuations and flicker with both low and high voltage systems. Quality Energy installed a Static Var Generator with a response time of less than 10ms, improving energy efficiency and providing energy savings.
  3. After conducting a power quality analysis for Jalna, Quality Energy found high harmonics were causing machinery malfunctions and unplanned shutdowns. After installation of an Active Harmonic Filter, Jalna was able to prevent machine malfunction issues and improve its packaging plant’s uptime.
