Harmonic Study and Analysis
Find Out What It's All About
Care Labs provides thorough harmonic research and analysis along with electrical installation services such as safety inspections, testing, calibration, and certification. Professionals will assess your electrical safety program’s harmonic risks, training materials, paperwork, and personal protective equipment (PPE) to make sure it is up-to-date, comprehensive, and compliant. Care Labs can identify harmonics early on and take the required actions to reduce the effects of harmonic distortions to ensure the equipment’s safety.
What is Involved
An electrical system can become inefficient due to harmonic voltages and currents. They produce ineffective heat and may deteriorate the quality of the electricity generated. The mathematical method of harmonic voltage analysis is used to forecast probable resonances and levels of harmonic distortion. A mathematical method for forecasting potential resonances and harmonic distortion levels based on empirical data is harmonic voltage analysis.
Harmonic frequencies are added to the electrical system by nonlinear electrical switching equipment such as AC variable frequency drives, DC drives, fluorescent lights, and computers. The danger of equipment failure is significantly increased by high voltage/current harmonic levels. As a result, a timely harmonic investigation and analysis are required. Currently, there are 5% harmonic restrictions in systems employing 415 volts, with 4% odd harmonics and 2% even harmonics.
Harmonic Distortion Consequences:
- Responsible for high voltage and circulating current.
- Device failure and destruction because of severe voltage distortion.
- A rise in the internal energy of components, which leads to component failure and a shortened lifespan.
- Fault-induced tripping of branch circuit breakers.
- Measurement flaw.
- Electrical and distribution system fires and explosions.
- Generator failures.
- A reduction in system power factor.
- Installation and utility costs are costly.
- Productivity reductions.
- Inactivity and unnecessary driving.
- Use of larger motors.
Harmonic issues are exceedingly rare, but when they do arise, they tend to decrease the power system’s dependability, power quality, and efficiency. Hence, harmonic investigation and analysis are important.
- Protects against current and voltage harmonics.
- Limitation of frequency variance.
- Unbalanced current and voltage.
- Enhance power factor analysis and maintain a value close to one.
- Regulates voltage fluctuations.
Harmonic research and analysis will provide insight into the probable source and effect of power quality issues, aiding in the avoidance of harmonic-related difficulties during the design phase and decreasing the likelihood of unintended repercussions.
Care Labs' workflow for harmonic analysis and research:
- Highlight available nonlinear loads, capacitor banks, and long medium-voltage cables on the electrical single-line diagram.
- Determine the PCC (point of common coupling).
- Locate system buses inside the facility that are sensitive to harmonic distortions.
- Get harmonics information for all nonlinear loads.
- Get vital information on voltage and current harmonics at the selected PCC, including the highest and lowest levels of short circuit faults.
- Do a harmonic analysis of the electrical network using ETAP (electrical transient analysis program).
- Determine the overall and discrete current and voltage wave distortion levels at the buses and PCC.
- Sketch the spectrum of harmonic frequencies.
- A suitable mitigation strategy is proposed and implemented if harmonic distortion levels surpass acceptable thresholds.
- After implementing the mitigation solution, rerun the analysis.
Benefits of Care Labs' Services:
If background harmonics have previously been detected, a higher rating is used in the second stage.
- Stage 2 permits variable converter size based on fault level and converter type if the backdrop is less than 25%.
- 50% of the permitted converter grade may be utilized if the backdrop is between 25% and 75%.
- On the top backdrop, a thorough harmonic analysis is done.
