Harmonic Study and Analysis
Find Out What It's All About
CareLabs offers comprehensive research and analysis on harmonics in addition to electrical installation services including safety inspections, testing, calibration, and certification. Professionals will evaluate the harmonic dangers, training materials, paperwork, and personal protective equipment (PPE) of your electrical safety program to ensure that it is current, exhaustive, and compliant. CareLabs can detect harmonics early on and take the necessary steps to decrease the impact of harmonic distortions to ensure the equipment’s safety.
What is Involved
Due to harmonic voltages and currents, an electrical system might become ineffective. They emit inefficient heat and may degrade the quality of the generated power. The mathematical technique of harmonic voltage analysis is used to predict resonances and harmonic distortion levels. Harmonic voltage analysis is a mathematical approach for predicting potential resonances and harmonic distortion levels based on empirical data.
Nonlinear electrical switching equipment such as AC variable frequency motors, DC drives, fluorescent lights, and computers introduce harmonic frequencies to an electrical system. High voltage/current harmonic levels increase the risk of equipment failure. Consequently, prompt study and analysis of harmonics are essential. Currently, systems utilizing 415 volts have harmonic limits of 5%, 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 needless driving
- Use of bigger motors
Harmonic difficulties are extremely uncommon, but when they do occur, the dependability, quality, and efficiency of the power system tend to deteriorate. Therefore, harmonic study and analysis is essential.
- Protects against voltage and current harmonics
- Voltage and current imbalances.
- Restriction of frequency volatility.
- Improves power factor analysis and keeps results near to one.
- Controls change in voltage.
With the use of harmonic research and analysis, which will provide light on the origin and impact of power quality concerns, it will be simpler to avoid harmonic-related problems during the design phase and less likely that unintended consequences would emerge.
Workflow of Carelabs for Harmonic Analysis and Research:
- Highlight available nonlinear loads, capacitor banks, and lengthy 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 greatest and lowest levels of short circuit faults.
- Do a harmonic analysis of the electrical network using ETAP.
- Determine the overall and individual current and voltage wave distortion values at the buses and PCC.
- Sketch the spectrum of harmonic frequencies.
- If harmonic distortion levels surpass acceptable thresholds, a suitable mitigation strategy is offered and implemented.
- After implementing the mitigation solution, rerun the analysis.
Advantages of Carelabs's Offerings:
If background harmonics have been discovered earlier, a higher rating is applied in the second step.
- Stage 2 allows variable converter size dependent on fault level and converter type if the background is less than twenty-five percent.
- If the background is between 25% and 75%, 50% of the authorized converter grade may be utilized.
- On the top background, a comprehensive harmonic analysis is performed.
