Power Quality Audit  Want us to call you

Objective – Power Quality Audit:

Client intends to assess its electrical service infrastructure and equipment for the harmonic analysis study in order to determine the source of power quality problems and to devise a solution to that problem which includes:

  • Analysing the quality of power by finding the levels of current and voltage harmonics, power factor etc.
  • Suggesting measures to overcome the identified power quality problems

Scope of the Study:

To achieve the objective of this study, the power quality shall be assessed based on following parameters:

  1. Harmonics - sinusoidal voltages or currents having frequencies that are integer multiples of the frequency at which the supply system is designed to operate
  2. Phase-phase/Neutral RMS voltage variations.
  3. Frequency variations
  4. Ground - Neutral RMS voltage variations.
  5. Load RMS current variations
  6. Power Factor - Improvement in power factor

Reference Standards:

The following International Standards are used to assess the power quality.

  1. IEEE – 519:1992 - “Recommended Practices and Requirements for Harmonic Control in Electrical Power Systems”.
  2. IEEE – 1159:1992 - “Recommended Practice for Monitoring Electric Power Quality and measuring power quality events”

At Sparrow, we are using the widely accepted IEEE 519: 1992 standard and IEEE 1159:1995 along with the best industrial practices to assess the power quality.
