Harmonic Study & Analysis

CareLabs‘ electrical installation services include safety inspections, testing, calibration, and certification, as well as comprehensive harmonic research and analysis. Trained specialists will assess harmonic risks, training programs, paperwork, and personal protective equipment (PPE) to ensure that your electrical safety program is current, compliant, and comprehensive. To ensure the safety of the equipment, CareLabs can discover harmonics early on and take the necessary measures to reduce their effects.

Harmonic voltages and currents inside the electrical system can result in inefficiency. They generate unnecessary heat and have the potential to degrade the quality of the electricity. Harmonic voltage analysis is a mathematical approach used to estimate possible resonances and degrees of harmonic distortion. Harmonic voltage analysis is a mathematical technique for determining potential resonances and harmonic distortion levels based on collected data.  

Nonlinear electrical switching equipment, including AC variable frequency drives, DC drives, fluorescent lights, computers, and so on, introduces harmonic frequencies into the electrical system. There is a large danger of equipment failure when harmonic voltage/current levels are high. Therefore, timely harmonic analysis and research are essential. Harmonic restrictions in 415 voltage systems are currently fixed at 5%, with 4% odd harmonics and 2% even harmonics. 

Harmonic Distortion Effects:
  • Charged for managing circulating current and high voltage.
  • Excessive voltage distortion causes equipment failure and damage.
  • The accumulation of internal energy in components leads to component breakdown and a shortened lifespan.
  • The branch circuit breaker trips due to a malfunction.
  • Error measurement

  • Explosions and fires in the distribution and wiring system
  • Power outages due to generators
  • A decrease in system power factor
  • Installation and utility expenses are astronomical.
  • Productivity is falling
  • Downtime and unnecessary travel
  • Utilization of bigger engines

Harmonic issues are extremely rare, but when they do occur, they negatively impair the power system’s dependability, power quality, and efficiency. Therefore, harmonic investigation and analysis are important. 

  • It provides protection against voltage and current harmonics.
  • Restriction of frequency variation
  • Uneven voltage and current
  • Improve power factor analysis and maintain a value around one.
  • Voltage variations are controlled.

Harmonic research and analysis will provide light on the probable causes and effects of power quality issues, aiding in the avoidance of harmonic-related difficulties during the design phase and reducing the likelihood of unexpected consequences.

Harmonic Analysis and Research Workflow at CareLabs:
  • On the electrical one-line diagram, emphasize accessible nonlinear loads, capacitor banks, and medium voltage cables of considerable length.
  • Determine the common point of connection (PCC)
  • Determine which system buses inside the facility are susceptible to harmonic distortions.
  • Collect harmonics data for all nonlinear loads.
  • Obtain vital information about voltage and current harmonics at the specified PCC, including the maximum and minimum levels of short circuit faults and the allowable harmonic values in Australia.
  • ETAP is used to do harmonic analysis on the electrical network.
  • Calculate the aggregate and discrete current and voltage wave distortion values at the buses and PCC.
  • Create a graph representing the spectrum of harmonic frequencies.
  • If harmonic distortion levels exceed allowable limitations, an appropriate mitigation approach is devised and implemented.
  • Rerun the analysis after installing the mitigation solution.

Advantages of CareLabs Service:

If background harmonics have previously been measured, then the values for Stage 2 are greater.

  • Stage 2 permits adjusting the size of the converter based on fault level and converter type if the background is less than 25 percent.
  • If the background is between 25% and 75%, converter ratings of half the amount specified above are acceptable.
  • For the upper backdrop, a thorough harmonic analysis is conducted.
