Trained professionals will review the harmonic risks, training programs, documentation, and personal protective equipment (PPE) of your electrical safety program to verify that it is up-to-date, legal, and exhaustive. Care Labs is able to identify harmonic distortions early on and minimize their consequences to ensure the safe operation of equipment. Harmonics are electric voltages and currents that can affect an electrical system’s performance. They are inefficient at heating and may affect power quality. Harmonic voltage analysis is a mathematical technique for forecasting potential resonances and harmonic distortion degrees. Harmonic voltage analysis is a mathematical method that forecasts probable resonances and harmonic distortion levels by analysing data. Nonlinear switching equipment, including AC variable frequency drives, DC drives, fluorescent lights, computers, etc., introduces harmonic frequencies into the electrical system. When voltage and current levels are high due to harmonics, the chance of equipment failure is significant. Consequently, it is crucial to learn and analyze harmonics at the proper time. The current harmonic limit for 415-volt systems is 5%, with 4% of harmonics being odd and 2% even.

Effects of Harmonic Distortion:

  • It is responsible for the circulation of high voltage and current.
  • Equipment failure and destruction because of significant voltage distortion
  • An increase in the amount of internal energy in components, leading in greater fragility and a shorter lifespan.
  • Failures that cause branch circuit breakers to trip
  • Errors in measuring
  • Wiring and distribution system explosions and fires
  • Breakdown of generators
  • The decrease in the system power factor
  • The installation and utility costs are costly.
  • Reduced efficiency
  • Not required are unnecessary downtime and driving around.
  • Employing bigger engines

Harmonic difficulties are infrequent, but when they do arise, they tend to diminish the dependability, quality, and efficiency of the power system. Consequently, it is necessary to study and assess harmony.

  • Protection from current and voltage harmonics
  • Frequency variations are restricted.
  • Voltage and current that are out of sync
  • Enhance power factor analysis and keep a close to one value.
  • Regulates voltage fluctuations

The research and analysis of harmonics will aid in discovering what may be causing power quality concerns. This will assist in avoiding design challenges associated with harmonics and decrease the chance of unwanted effects. 

Workflow of Harmonic Study and Analysis at Care Labs:

  • Highlight the nonlinear loads, capacitor banks, and long medium-voltage cables on the electrical circuit’s single-line design.
  • Find the connecting point (PCC)
  • Determine which system buses are prone to harmonic distortions inside the facility.
  • Gather harmonics information for all nonlinear loads.
  • Obtain crucial information on the voltage and current harmonics at the chosen PCC, including the maximum and lowest short circuit fault levels.
  • ETAP is used to analyze the electrical network’s harmonics.
  • Determine the total and individual values of voltage and current wave distortion at the buses and PCC.
  • Draw the frequency spectrum for the harmonics.
  • If the levels of harmonic distortion surpass the acceptable threshold, a solution is proposed and applied.
  • Rerun the analysis once the countermeasure has been implemented.

Care Labs's Service Benefits:

If harmonics in the background have already been measured, the second stage consists of higher ratings.

  • Stage 2 permits the converter size to change according to the fault level and kind of converter if the backdrop is less than 25%.
  • If the background is between 25 and 75%, the converter ratings may be decreased by 50%.
  • For the top background, a thorough harmonic analysis is performed.
