Power Quality and Harmonics Audit

Delta CFS offers the Power Quality and Harmonics Audit service which aims to check the availability of the power supply (continuity) and the quality of the voltage.A reliable, efficient and healthy supply of electrical power is essential to ensure the productivity of your manufacturing process and facility. Poor quality of the electrical installations, nonlinear loads disturbances, and imbalance which can affect the normal operation of the equipment and cause unwanted disruptions and downtime. If this left unattended by the facility team can lead to unwanted consequences like:

  • Failure of Transformer and motor Windings.
  • Frequent and unusual tripping of Breakers and protection relays.
  • Raise in cost of Energy bills and penalties
  • Failure of sensitive equipments
  • Failure of Electronic control cards.

We will perform a detailed analysis of the entire electrical power distribution system from the transformer input and downstream critical feeders to identify the hidden Power Quality issues and the source of Harmonic distortions in the Electrical facility. Based on the site physical observations and data collection, our expert team will form a solution part recommending the best practices and solutions to resolve all issues identified in the study.

Delta CFS captures your power related problems like:

  • Harmonics distortion level (%Vthd &%Ithd).
  • Transients and flickers
  • Frequency variation
  • Voltage sags and swells.
  • Voltage and Current Unbalance
  • Power factor

Why are Power Quality and Harmonic Audits important?

  • Harmonics study unfolds and avoids impact due to excessive harmonic currents in transformers and capacitor banks.
  • Increase in the available capacity of the electrical infrastructure due to reduced loading of transformers, switchgear & cables
  • Reduced failure of sensitive electronic and precision equipments and ensures equipment will not malfunction due to excessive harmonic voltage distortion.
  • This audit helps to maintain utility voltage and current harmonic distortion level requirements.
  • Improved reliability and health condition of the electrical power distribution system

Harmonics are caused by non-linear load which draws a nonsinusoidal current from a sinusoidal voltage source. Harmonic studies should be considered whenever there are nonlinear loads and capacitor banks I the power system. Higher levels of harmonic producing loads are electric arc furnaces, static VAR compensators, inverters, DC converters, switch-mode power supplies, and AC or DC motor drives, welding machines, VFD, Computer and printer devices.
