Power Quality Monitoring & Analysis for Critical Electrical Infrastructure
Identify the root cause of voltage dips, harmonics, transients, nuisance tripping and recurring electrical faults before they affect reliability, equipment performance or site resilience.
ACTENIQ provides engineering-led power quality monitoring and analysis for critical electrical infrastructure, helping organisations understand what is happening across their network, why it is happening and what action is needed to improve performance.
Could poor power quality be the cause of your recurring faults?
Power quality describes the condition of your electrical supply and how well voltage, current, frequency and waveform characteristics support the reliable operation of your equipment.
But power quality issues are not always obvious. They often show up as nuisance tripping, equipment resets, overheating, unexplained faults, poor performance or repeated disruption across site equipment.
For critical sites, poor power quality is not just a technical issue. It can affect uptime, asset life, energy efficiency, operational resilience and maintenance costs.
Voltage dips and brownouts
May cause control faults, equipment trips, resets and process disruption
Voltage swells, overvoltage & undervoltage
Can stress equipment, affect stability and shorten asset life
Harmonics and waveform distortion
Often caused by non-linear loads and can lead to overheating, losses and reduced efficiency
Poor power factor
Can increase reactive power demand, network losses and potential charges.
Transients and disturbances
Short-duration events that can affect sensitive equipment and system stability.
Excessive loading and imbalance
Can reduce capacity, increase losses and accelerate ageing across electrical assets.
Temporary or Permanent
Power Quality Monitoring?
Not every site needs the same monitoring approach.
ACTENIQ can support short-term investigations, semi-permanent monitoring or fixed power quality monitoring systems depending on the issue, site risk and operational requirement.
Temporary / Semi-Permanent Monitoring
- Best for investigating recurring faults, nuisance tripping, suspected harmonics, voltage dips or short-term performance concerns.
- Captures power quality data over a defined period while the site operates under real conditions.
- Useful for identifying likely causes and recommending corrective action.
Permanent
Monitoring
- Useful for long-term performance tracking, validation of improvements and stronger operational decision-making.
- Best for critical sites, variable loads, compliance needs, high downtime risk or ongoing assurance.
- Provides continuous visibility, event logs, trend data and recurring issue detection over time.
What our Power Quality Monitoring Reveals
Power quality monitoring helps teams move beyond symptoms and understand what is happening across the electrical network. It can reveal whether issues are linked to supply conditions, on-site equipment, connected loads, power factor, harmonics, overload, imbalance or wider network behaviour.
Monitoring can help identify:
- Voltage dips, swells and interruptions
- Harmonics and waveform distortion
- Poor power factor and reactive power demand
- Transients and disturbances
- Overloaded assets or changing load profiles
- Root causes behind nuisance tripping or recurring faults
- Evidence to support compliance, reporting or correction actions
From Recurring Issues to Practical Mitigation
Power quality data alone is not enough.
ACTENIQ combines advanced monitoring technology with engineering interpretation to translate electrical behaviour into actionable insight.
Our approach includes:
- Strategic monitoring deployment
- High resolution disturbance detection
- Data interpretation by electrical specialists
- Identification of root causes
- Practical recommendations for mitigation
Once the cause is understood, ACTENIQ can recommend the most appropriate mitigation route based on your electrical conditions, operational priorities and infrastructure requirements.
Power Factor Correction
Helps reduce reactive power demand, improve network efficiency and support better use of electrical capacity.
Harmonic Filtering
Helps reduce waveform distortion caused by non-linear loads, protecting equipment from overheating, nuisance operation and reduced efficiency.
Voltage Support or sag Correction
Helps smooth voltage dips and maintain continuity for sensitive or critical loads.
Combined Corrective Solutions
Some sites require a combination of technologies, infrastructure changes or operating adjustments to address the root cause properly.
Frequently Asked Questions
What is power quality monitoring?
Power quality monitoring measures the health of your electrical supply by analysing parameters such as voltage, current, frequency, harmonics, power factor, transients, sags, swells and loading.
It helps identify electrical issues that may reduce equipment reliability, increase energy costs or cause unexpected downtime before they become more significant problems.
What are common signs of power quality issues?
Common indicators include nuisance tripping, unexplained equipment resets, flickering lighting, overheating, voltage dips, brownouts, harmonic distortion, poor power factor and recurring electrical faults with no obvious cause.
If these symptoms occur regularly, a power quality survey can help identify the underlying cause.
What causes poor power quality?
Power quality issues can originate from the incoming utility supply or be generated within your own electrical installation.
Common causes include non-linear loads, variable speed drives, EV charging infrastructure, HVAC equipment, renewable energy systems, overloaded electrical networks, harmonic distortion, poor power factor and rapidly changing loads.
Do I need a temporary power quality survey or permanent monitoring?
It depends on your objective.
Temporary power quality surveys are ideal for investigating a specific issue over a defined period, validating complaints or understanding how a network behaves under normal operating conditions.
Permanent monitoring provides continuous visibility of electrical performance and is best suited to critical facilities, changing electrical loads or sites where ongoing compliance, reliability and operational resilience are priorities.
Can ACTENIQ help resolve power quality issues?
Yes. Monitoring is only the first step.
ACTENIQ’s engineers interpret the survey data, identify likely root causes and recommend practical solutions such as harmonic filtering, power factor correction, voltage support, load balancing or wider electrical infrastructure improvements.
Can power quality monitoring be installed without disrupting operations?
Yes. Most power quality monitoring equipment can be installed with minimal disruption, with many deployments completed during planned maintenance windows.
Our engineers are experienced in working within live operational environments and tight shutdown windows, ensuring monitoring systems can be installed safely and efficiently whilst minimising disruption to site operations.
Do your power quality monitoring systems require a cloud connection?
No. ACTENIQ can provide local, hybrid or cloud-connected monitoring solutions depending on your operational, cyber security and data management requirements.
Our temporary power quality monitoring systems include secure remote connectivity as standard, allowing both your team and ACTENIQ’s engineers to access live data, investigate events and review survey results without returning to site. The same monitoring platform used for our temporary deployments is also available as a fully featured on-premise solution for customers who require complete local control.
For permanent installations, monitoring can integrate with existing Power Monitoring Systems (PMS), BMS, SCADA, DCIM and energy management platforms. Alternatively, ACTENIQ can deploy a complete monitoring solution, combining power quality monitoring, energy metering and electrical asset monitoring into a single integrated platform with local, hybrid or cloud-based access.
How do I know if a power quality problem is coming from the utility or my own site?
Determining the source of a power quality issue often requires monitoring at multiple points across the electrical network.
By installing power quality monitoring at the incoming supply and across key distribution points, ACTENIQ can establish whether disturbances originate from the utility network or are being generated by equipment within your own installation. This enables corrective action to be targeted at the true source of the problem, avoiding unnecessary expenditure and reducing investigation time.
