Frequently Asked Questions


What is a power analyser?

A power analyser is a device used to measure the flow of electrical power (expressed in watts, W) within an electrical system. It assesses the rate of energy transfer between a power source and a load. Essentially, it helps determine how efficiently electrical energy is being utilised and helps with troubleshooting potential issues.


What is the difference between a power meter and a power analyser?

A power meter is a straightforward instrument that measures basic electrical parameters such as voltage (V) and current (A). It computes essential power-related results.

In contrast, a power analyser goes beyond basic measurements. It provides more advanced analysis capabilities, including assessing power quality, harmonics, and other complex parameters. Power analysers are suitable for detailed studies and troubleshooting.


What is the purpose of a power quality analyser?

The primary purpose of a power quality analyser is to assess and monitor the quality of electrical power within a system. It ensures that the power supplied is compatible with the connected load, preventing premature equipment failure or malfunction. Power quality analysers help identify issues like voltage fluctuations, harmonics, and transients.


What is 3 phase power analyser?

A 3-phase power analyser specifically deals with three-phase electrical systems. It measures parameters in 3-phase circuits, including voltage, current, power factor, and harmonics. These analysers are crucial for industrial and commercial applications where 3-phase power distribution is common.


What is the difference between a power logger and a power quality analyser?

A power logger records data over an extended period, capturing trends and variations in power consumption. It’s useful for energy audits and load profiling.

A power quality analyser, on the other hand, focuses on assessing the quality of power. It identifies issues related to harmonics, voltage sags, swells, and transients. Power quality analysers provide detailed insights into system performance.


Why do we measure power quality?

Measuring power quality is essential because poor power quality can lead to equipment damage, malfunctions, and safety hazards. By assessing power quality, we can ensure reliable operation, prevent downtime, and maintain efficient electrical systems.


What is a power quality meter?

A power quality meter is another term for a power quality analyser. It measures and analyzes various power-related parameters to evaluate the overall quality of electrical supply.


Where are power quality meters used?

Power quality meters find applications in various settings:

  • Industrial Facilities: To monitor and maintain power quality in manufacturing plants, factories, and production lines.
  • Commercial Buildings: For assessing power quality in offices, shopping centres, and other commercial spaces.
  • Utilities: To monitor grid power quality and ensure compliance with standards.
  • Research and Testing Labs: For in-depth studies and analysis of power systems.
  • Energy Audits: To identify energy-saving opportunities and improve efficiency.
  • Maintenance and Troubleshooting: To diagnose power-related issues and prevent equipment failures.
