Harmonic Study & Analysis

CareLabs offers electrical installation services such as electrical safety inspections, testing, calibration, and certification in addition to full research and analysis of harmonics. Experts will review harmonic threats, training programs, documentation, and personal protective equipment to determine whether your electrical safety program is up to date, compliant, and thorough (PPE (Personal Protective Equipment).

To protect the equipment, CareLabs can recognize harmonics early and take the necessary steps to limit their impact. Harmonic electric voltages and currents can make electrical systems less effective. They have the capacity to lower the caliber of power and produce useless heat. Harmonic voltage analysis is a mathematical technique for anticipating probable resonances and harmonic distortion levels. Harmonic voltage analysis is a mathematical technique for forecasting potential resonances and harmonic distortion levels using empirical data. 

Harmonic frequencies are incorporated into the electrical system through nonlinear electrical switching devices including AC variable frequency motors, DC drives, fluorescent lights, and computers. High harmonic voltage/current levels pose a danger of equipment failure. Making a rapid harmonic analysis and study is essential. The current harmonic limitations for 415-volt systems are 5%, with 4% odd harmonics and 2% even harmonics. 

Consequences of Harmonic Distortion
  • Responsible for both high voltage and circulating current.
  • Equipment failure and destruction are caused by significant voltage distortion.

  • Increased internal energy in a component result in failure and a shorter lifespan.
  • Branch circuit breakers malfunction and trip.
    Measuring blunder
  • Electrical and distribution system fires and explosions
  • Generator problems
  • System power factor dropped
  • Installation and electricity fees that are expensive
  • Decreased productivity
  • Passivity and pointless driving
  • Using more powerful motors

Even though harmonic issues are exceedingly rare, when they do arise, they tend to lower the power system’s dependability, power quality, and efficiency. Research and study of harmonics are so essential. 

  • Protections from harmonic current and voltage
  • Limit on frequency variation
  • Unbalanced current and voltage
  • Boost power factor analysis and maintain a value close to one.
  • Peaks and troughs in voltage

Harmonic research and analysis will clarify the likely source and impact of power quality challenges to minimize harmonic-related issues during the design phase and lower the risk of unanticipated repercussions. 

Workflow at CareLabs for Harmonic Study and Analysis:
harmonic-4
  • Draw specific attention to any potential nonlinear loads, capacitor banks, and lengthy medium-voltage cables on the electrical single-line diagram.
  • It is important to determine what connects everything (PCC)
  • Identify the system buses in the building that are prone to harmonic distortions.
  • Gather harmonics information for each nonlinear load.
  • Learn critical information about the voltage and current harmonics at the selected PCC, including the maximum and minimum levels of short circuit faults.
  • Analyze the harmonics of the electrical network using ETAP.
  • Determine the overall and individual current and voltage wave distortion values for the buses and pccs.
  • The harmonic frequency spectrum should be represented graphically.
  • If harmonic distortion levels are too high, a suitable mitigation strategy is recommended and applied.
  • After implementing the mitigation strategy, rerun the study.
Advantages of the CareLabs Service

If background harmonics have previously been detected, higher ratings are applied in the second step.

  • Stage 2 allows changing the converter size depending on the fault level and converter type if the backdrop is less than 25%.
  • If the backdrop is between 25% and 75%, the lower half of the converter grade is appropriate.
  • For the top background, an extensive harmonic analysis is performed.
