Active Harmonic Filters: A Guide to Effective Installation and Maintenance

Quality Energy • Aug 23, 2023


Active Harmonic Filters (AHFs) are one of the most effective solutions for enhancing power quality and optimising energy consumption. However, the journey to reap the full benefits of AHFs doesn't stop after design. Proper installation, regular upkeep, and meticulous maintenance all play a pivotal role in ensuring these devices' longevity and sustained performance. In this article, we share a comprehensive guide to installing, maintaining, and caring for AHFs, enabling Australian businesses to maximise their investment and enjoy uninterrupted power quality improvements.

The Importance of Proper Installation


The effectiveness of Active Harmonic Filters begin with a meticulous installation process that considers various factors:


  • Expertise matters: Installing Active Harmonic Filters is a specialised task that demands technical expertise. Ensure you’re engaging experienced professionals who possess knowledge of power quality solutions, harmonic profiles, and AHF configurations.
  • Location and environment: Choose an appropriate location for the AHF installation. Ensure it is protected from adverse environmental conditions, such as extreme temperatures, humidity, and dust. Such precautions safeguard the device's performance and lifespan.
  • Electrical compatibility: Ensure the Active Harmonic Filter is compatible with the existing electrical system. Harmonic assessments and load profiles aid in determining the appropriate AHF capacity and configuration.
  • Integration with control systems: Active Harmonic Filters often integrate with existing control and monitoring systems. Proper integration ensures seamless communication and real-time monitoring, enhancing power quality management.

Regular Upkeep for Optimal Performance


Maintaining AHFs involve regular checks and preventative measures to maintain their effectiveness:


  • Routine visual inspections: Periodic visual inspections allow operators to identify any physical damage, loose connections, or signs of wear. Addressing these issues promptly prevents them from escalating into major problems.
  • Monitoring software updates: Manufacturers often release software updates to enhance AHF performance and address potential bugs. Regularly updating the software ensures that the AHF operates with the latest features and improvements.
  • Calibration checks: Calibrate the AHF regularly to ensure its readings and responses align with the electrical conditions. This step guarantees accuracy and reliability in power quality management.
  • Temperature and cooling considerations: Monitor the operating temperature of the AHF. Overheating can lead to reduced performance and even damage. Adequate cooling and ventilation mechanisms should be in place to maintain optimal temperature levels.


Preventative Maintenance for Prolonged Longevity

Proactive measures are pivotal to extending the lifespan and effectiveness of AHFs:


  • Cleaning and dust control: Regularly clean the AHF's exterior to prevent dust buildup that could hinder proper ventilation and cooling. A dust-free environment aids in heat dissipation and ensures consistent performance.
  • Inspecting internal components: While AHFs are enclosed devices, internal components can still accumulate dust and contaminants. Periodically inspect and clean interior components to prevent their degradation over time.
  • Capacitor checks: Capacitors are critical components of AHFs. Regularly assess their condition, checking for signs of leakage, bulging, or overheating. Replacing aging capacitors pre-emptively avoids performance issues.
  • Harmonic assessment: Conduct periodic harmonic assessments of the electrical system to ensure that the AHF effectively mitigates harmonics. Adjustments can be made if the harmonic profile changes over time.


Partnering with Professionals for Maintenance

While routine maintenance can be performed by on-site personnel, engaging professionals offers distinct advantages:


  • Expertise: Professionals possess in-depth knowledge of AHFs and their intricacies, ensuring that maintenance tasks are executed accurately.
  • Diagnostic Tools: Professionals often utilise advanced diagnostic tools to identify potential issues and anomalies that might go unnoticed during routine checks.
  • Timely Intervention: Professionals can detect problems early and take preventative actions to avoid major breakdowns or performance deterioration.
  • Performance Optimisation: Maintenance professionals can fine-tune AHFs for optimal performance based on real-time monitoring and assessment.
