Harmonic Study and Analysis

Electrical installation services provided by CareLabs include electrical safety inspections, testing, calibration, and certification, and thorough harmonic research and analysis. Trained professionals will evaluate harmonic threats, training programs, documentation, and personal protective equipment (PPE) to verify that your electrical safety program is up to date, compliant, and complete.

CareLabs can detect harmonics early on and take appropriate steps to mitigate the impact of harmonic distortions to ensure the equipment’s safety. Harmonic voltages and currents in the electrical system can generate inefficiencies. They produce wasteful heat and have the potential to decrease power quality. Harmonic voltage analysis is a mathematical technique for estimating potential resonances and harmonic distortion levels. Based on data, harmonic voltage analysis is a mathematical method for estimating potential resonances and harmonic distortion levels.

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. There is a substantial risk of equipment malfunctioning with high harmonic voltage/current levels. As a result, prompt harmonic analysis and study are vital. Harmonic limitations are currently set at 5% in 415 voltage systems, with 4% odd harmonics and 2% even harmonics.

Effects of Harmonic Distortion:

It circulates current and high voltage.
Excessive voltage distortion causes equipment failure and damage.
The existence of internal energy in components increases, resulting in part failure and a shorter life duration.
Branch circuit breaker trip owing to a fault
Error measurement
Explosions and fires in the wiring and distribution system
Outages caused by generators
A reduction in the system power factor
Installation and utility costs are exorbitant.
Productivity declines
Downtime and unneeded road trips
The utilization of larger motors

Harmonic difficulties are highly unusual to arise, but when they do, they have a negative impact on power system reliability, power quality, and efficiency. As a result, harmonic research and analysis are critical.

It safeguards against voltage and current harmonics.
Limitation on frequency fluctuation
Voltage and current imbalance
Enhance power factor analysis and keep the value close to one.
Voltage fluctuations are regulated.

Harmonic research and analysis will supply insight into the potential causes and effects of power quality concerns, helping in the avoidance of harmonic-related issues during the design stage and lowering the risk of unintended consequences.

Harmonic Analysis and Study Work Process at CareLabs:

Highlight accessible nonlinear loads, capacitor banks, and medium voltage cables of lengthy length on the electrical one-line diagram.
Decide the point of common connection (PCC)
Find which in-plant system buses are prone to harmonic distortions.
Gather harmonics information from all nonlinear loads.
Obtain crucial data on voltage and current harmonics at the selected PCC, including the maximum and lowest short circuit fault levels.
Conduct harmonic analysis on the electrical network using ETAP (Electrical Transient Analysis 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 proposed and applied.
After implementing the mitigation solution, rerun the analysis.

Advantages of CareLabs Service:

Stage 2 entails higher ratings if the background harmonics have already been measured.

Stage 2 allows for changing converter size based on fault level and converter type if the background is less than 25%.
Converter ratings of half the amount mentioned above are permissible if the backdrop is between 25% and 75%.
For higher background, a comprehensive harmonic study is carried out.
