Power Quality

Analysing power quality is a fundamental and crucial mode of inspection within electrical infrastructure. To support this, power quality analysis using TEGG methods, allows us to retrieve the most comprehensive data possible.
For example, we are able to easily record variable data, such as the measurements below:

  • Current RMS
  • Voltage RMS
  • Millivolt drop readings
  • Total harmonic distortion

This will enable us to see how clean power is during normal working use and highlight further anomalies such as:

  • Elevated harmonics
  • Current imbalance
  • Voltage imbalance
  • High earth currents
  • Overloaded circuits

The signs of poor power quality could be:

  • Transformer failures
  • Utility fines
  • Rotary equipment failures
  • Circuit breakers tripping
