Harmonic Study and Analysis
Find Out What It's All About
Care Labs offers comprehensive harmonic research and analysis along with electrical installation services such as electrical safety inspections, testing, calibration, and certification. To confirm that your electrical safety program is current, compliant, and comprehensive, experts will examine harmonic risks, training programs, paperwork, and personal protective equipment (PPE).
What is Involved
To ensure the safety of the equipment, CareLabs can detect harmonic distortions early on and take appropriate measures to lessen their effects. Electrical systems can become inefficient when there are harmonic electric voltages and currents. They generate ineffective heat and have the potential to degrade the quality of power.
A mathematical method for predicting potential resonances and harmonic distortion levels is harmonic voltage analysis. Harmonic frequencies are introduced into the electrical system by nonlinear electrical switching equipment such as AC variable frequency drives, DC drives, fluorescent lights, computers, and so on.
A significant risk of equipment failure is presented by high harmonic voltage/current levels. Therefore, it is crucial to do a quick harmonic analysis and research. Harmonic limitations for systems operating at 415 volts are currently 5%, with 4% for odd harmonics and 2% for even harmonics.
Effects of Harmonic Distortion
- Causes high voltage and flowing current.
- Equipment failure and destruction as a result of extreme voltage distortion.
- A rise in the amount of internal energy in components, which causes component failure and a shorter lifespan.
- Branch circuit breakers tripping due to faults.
- Measuring deviation.
- Explosions and flames in the distribution system’s wiring.
- Power outages brought on by generators.
- A decline in the system’s power factor.
- Expensive installation and utility costs.
- Productivity losses.
- Downtime and unnecessary vehicle trips.
- Larger motor size.
Although harmonic problems are extremely uncommon, when they do occur, they tend to reduce the reliability, power quality, and efficiency of the power system. Therefore, harmonic research and analysis are crucial.
- Offers harmonic voltage and current protection.
- Voltage and current imbalance.
- limitation on frequency fluctuation.
- Improve power factor analysis and keep it around one.
- Control voltage fluctuations.
Insight into the likely cause and effects of power quality problems will be provided through harmonic study and analysis, helping to prevent harmonic-related design challenges and reducing the likelihood of unexpected consequences.
CareLabs' Harmonic Analysis and Research Workflow
- Highlight from the electrical one-line diagram any possible nonlinear loads, capacitor banks, and lengthy medium voltage cables.
- Determine the location of the common connection (PCC).
- Determine which in-plant system buses are most susceptible to harmonic distortions.
- Obtain information about harmonics from all nonlinear loads.
- Obtain crucial information on the greatest and lowest short circuit fault levels as well as voltage and current harmonics at the chosen PCC.
- Utilize ETAP to conduct a harmonic analysis of the electrical network.
- Identify the whole and discrete levels of current and voltage wave distortions at the buses and the PCC.
- Draw a spectrum of harmonic frequencies.
- An appropriate mitigation solution is suggested and implemented if the harmonic distortion levels are higher than the allowable values.
- Perform the analysis again after including the mitigation strategy.
Benefits of CareLabs Service
Higher ratings are used in the second stage if background harmonics have already been measured.
- If the background is less than 25%, stage 2 allows for various converter sizes based on the fault level and converter type.
- The lower half of the aforementioned converter grade is acceptable if the background is between 25% and 75%.
- The top background is subjected to a thorough harmonic evaluation.
