Power Quality Audit

All electrical devices work properly without any failure, if input power is well within set limits of electrical properties. So Power Quality Study determines the health of the electrical to load ends. Without the proper power, an electrical device (or load) may malfunction, fail prematurely or not operate at all. There are many ways in which electric power can be of poor quality and many more causes of such poor quality power. The quality of electrical power may be described as a set of values of parameters, such as:

  1. Continuity of service
  2. Variation in voltage magnitude.
  3. Transient voltages and currents
  4. Harmonic content in the waveforms for AC power.

All these unwanted parameters can increase in power consumption, heating of equipment’s and wiring, malfunctioning or even damage.
Scope of work

We use Three Phase Power Quality Analyser for:

  1. Identify various Types of harmonics , Harmonic study
  2. Calculation for Total harmonic Distortion.
  3. Power Factor Study
  4. Identify ways to improve power factor.
  5. Energy consumption study
  6. Review of Single line diagram.
  7. Review of connected load.
  8. Variation of current and Voltages between phases.
  9. Measurement of input current and voltage.
  10. Comparison of the unbalancing with the prescribed limits.
