Harmonic Study and Analysis
Find Out What It's All About
CareLabs provides complete harmonic research and analysis in addition to electrical installation services including electrical safety inspections, testing, calibration, and certification. Experts will analyze harmonic threats, training programs, paperwork, and personal protective equipment to certify that your electrical safety program is current, compliant, and exhaustive (PPE (Personal Protection Equipment).
What is Involved
To ensure the safety of the equipment, CareLabs can identify harmonic distortions in a timely manner and take the necessary steps to mitigate their impact. When there are harmonic electric voltages and currents, electrical systems can become inefficient. They produce inefficient heat and have the potential to diminish power quality. Harmonic voltage analysis is a way to calculate resonances and levels of harmonic distortion. Harmonic voltage analysis is a mathematical approach for forecasting potential resonances and harmonic distortion levels based on data.
Nonlinear electrical switching equipment, such as AC variable frequency drives, DC drives, fluorescent lights, computers, and so on, introduces harmonic frequencies into the electrical system. High harmonic voltage/current levels pose a significant threat of equipment failure. Consequently, it is essential to do a rapid harmonic analysis and investigation. Currently, the harmonic constraints for 415-volt systems are 5%, with 4% for odd harmonics and 2% for even harmonics.
Effects of Harmonic Distortion:
- It circulates current and high voltage.
- Failure and destruction of equipment because of high voltage distortion.
- Increased internal energy in components, leading to component failure and a shorter life duration.
- Branch circuit breakers trip because of a defect.
- Error in measuring.
- Explosions and fires in the wiring and distribution systems.
- Outages in the power grid.
- A decrease in the system’s power factor.
- Installation and utility costs are exorbitant.
- Productivity decline.
- Unnecessary drive time.
- Using bigger motors.
Harmonic issues are exceedingly rare, but when they do arise, they tend to degrade the power system’s dependability, power quality, and efficiency. Consequently, harmonic study and analysis are needed.
- Offers protection against harmonic voltage and current
- Voltage and current imbalance.
- Frequency fluctuation restriction
- Enhance power factor analysis and maintain it around one.
- Control voltage fluctuations.
Harmonic study and analysis will give insight into the source and effects of power quality issues, therefore preventing harmonic-related design challenges and decreasing the chance of unanticipated outcomes.
Workflow for Harmonic Analysis and Research at CareLabs:
- Highlight accessible nonlinear loads, capacitor banks, and medium voltage cables of lengthy length on the electrical one-line diagram.
- Determine the point of common connection (PCC).
- Determine which in-plant system buses are prone to harmonic distortions.
- Get harmonics information from all nonlinear loads.
- Get essential data on voltage and current harmonics at the chosen PCC, including the maximum and lowest short circuit failure values.
- Conduct harmonic analysis on the electrical network using ETAP (Electrical Transient Analyzer Program,).
- Calculate the total and discrete levels of current and voltage wave distortions at the buses and the PCC.
- Make a graph of the harmonic frequency spectrum.
- If the levels of harmonic distortion surpass the permitted thresholds, a suitable mitigation strategy is recommended and applied.
- After implementing the mitigation solution, rerun the analysis.
CareLabs Service Benefits:
If background harmonics have previously been measured, higher ratings are applied in the second stage.
- If the background is less than 25%, stage 2 allows for different converter sizes depending on the fault level and converter type.
- If the backdrop is between 25 and 75 percent, the lower half of the converter grade is appropriate.
- The leading backdrop is subjected to a comprehensive harmonic analysis.
