Whether you in a manufacturing facility, data centre, industrial plant, hospital or commercial centre, a power quality analyzer must be at the heart of your energy management system



The term is used to describe electric power that drives an electrical load and the load’s ability to function properly. Without the proper power, an electrical device (or load) may malfunction, fail prematurely or not operate at all.


Today any interruption of business operations due to poor power quality has a direct impact on the profitability of an enterprise. The increased use of automation and electronic devices and their sensitivity to PQ problems turns the availability of electric power with quality into a crucial factor for competitiveness in every sphere of business activity.

The most critical areas are the continuous process industry and the information technology services. Insufficient power quality can inflict serious losses on business and economy. In the worst-case scenario, it may pose a threat to human life in mission critical applications and highly sensitive environments, such as hospitals.

Power quality monitoring and power quality improvement allows you to optimise and reduce power consumption – saving money on your electricity bill and thereby, your carbon footprint. Direct savings to consumers come from lower energy cost and reactive power tariffs. Indirect savings are gained by avoiding circumstances such as damage and premature aging of equipment, loss of production or loss of data and work.

It also reduces the risk of equipment overheating, malfunctioning or breakdown, and minimises ‘wear and tear’ so your equipment works better and lasts longer.



A power quality analyser is equipment used to measure electric power signals to determine the load’s ability to function properly with that electric power. Incorrect power quality can cause the electrical equipment to malfunction or fail prematurely.

Power quality analyzers are used for continuous electrical power quality monitoring, and to capture power quality and energy data so you can identify power quality and energy efficiency issues with ease. Flexible software enables visibility to invaluable insights about the performance of your electrical system.


Poor power quality can cause a multitude of problems which can negatively impact efficiency and sustainability of your facility. Some of these issues include:

  • insulation damage
  • pulsating torque in rotating machinery
  • interference with communication. control and signal circuits
  • reduced efficiencies
  • malfunction of equipment
  • increased operating temperature on equipment, cables, switchgears, motors, transformers
  • reduced equipment life
  • high maintenance costs
  • reduced capacitor life/capacitor failures
  • blown fuses and tripping of switchgear
  • increased copper losses

PQ monitoring and power quality analysis can help your energy management system tackle these problems. Trust a good PQA to:

  • Identify source and frequency of events
  • Establish precise location and timing of events
  • Assist in preventative and predictive maintenance
  • Develop maintenance schedules
  • Monitor and trend conditions
  • Analyze harmonics, flicker, transients, frequency variation, voltage variations (sag & swell)
  • Ensure equipment performance
  • Assess sensitivity of process equipment to disturbances
  • Evaluate performance against specifications

The PQA generates a final report that provides a complete picture of the electrical system’s correct state of operation. The report is a tool of primary importance for preventive maintenance, in that it lists all the measures to be taken promptly when disturbances are detected, before the negative impact on production and the running of the equipment is felt.
