Power quality plays a critical role in the reliability, efficiency and performance of modern electrical systems. Voltage sags, swells, harmonics, transients, interruptions and other disturbances can disrupt sensitive equipment, increase energy losses and contribute to unexpected downtime or premature equipment failure.
This page serves as your knowledge hub for power quality monitoring and analysis. From understanding common electrical disturbances and compliance standards to investigating equipment issues and improving network performance, you will find practical guidance, technical information and expert updates. Explore how advanced power quality analysers and monitoring software can help identify problems, verify performance and provide the data needed to maintain more stable and reliable electrical systems.
Data centres, hospitals, airports and other critical facilities depend on a stable electrical supply to maintain essential operations.
Voltage sags, transients, harmonics and interruptions can affect sensitive electronic equipment, trigger unexpected shutdowns and compromise system reliability. Continuous power quality monitoring helps facility operators detect disturbances, investigate their source and verify the performance of electrical infrastructure, UPS systems and backup generation. Reliable data supports faster fault investigation and helps reduce the risk of costly downtime.
Modern industrial sites use variable frequency drives, motors, automation systems and other non-linear loads that can introduce harmonics and additional stress into the electrical network.
Poor power quality may cause equipment overheating, nuisance tripping, reduced motor efficiency and premature component failure. Advanced monitoring provides visibility into harmonics, voltage imbalance, flicker, power factor and other electrical conditions. This allows operators to identify emerging problems, assess corrective measures and improve the reliability and efficiency of production equipment.
Electricity networks are becoming more complex as solar farms, wind generation, battery storage and distributed energy resources connect to the grid.
Power quality monitoring helps network operators and renewable energy developers assess voltage performance, frequency behaviour, harmonics and disturbances at critical connection points. Accurate data supports grid compliance, commissioning, disturbance investigation and ongoing performance verification. As Australia’s energy system continues to evolve, dependable power quality analysis is essential for maintaining a stable and resilient network.

Power quality monitoring is a fundamental requirement for ensuring the stability, efficiency and reliability of modern electrical networks, especially in critical infrastructure applications.
When it comes to choosing the right power quality meter, one of the key factors to consider is the accuracy class of the meter. Two of the most common accuracy classes in the industry are Class A and Class S.
In today’s energy-driven world, ensuring optimal power quality is crucial for maintaining the efficiency and reliability of electrical systems.
Power quality, or PQ for short, relates to the reliability and consistency of the electric energy delivered by the grid. Since the grid is a closed ecosystem, overall power quality is as well influenced by the character of electric loads feeding off the power grid.
As modern electrical grids evolve with the increasing integration of renewable energy sources and the complexities of smart grid technologies, the need for precise and comprehensive power quality (PQ) monitoring has never been greater.
The world is increasingly being powered by solar and wind, and switching to use Inverter-Based Resources to leverage these renewable energy sources.
