Harmonic Study and Analysis

Carelabs offers electrical installation safety inspection, testing, calibration, certification, and harmonic inquiry and analysis. Trained specialists will examine the harmonic dangers, training programs, paperwork, and personal protective equipment (PPE) of your electrical safety program to ensure that it is current, legal, and comprehensive.

Carelabs is able to detect harmonic distortions early on and take the necessary actions to mitigate their effects in order to ensure the safe operation of the equipment. Harmonics are electric voltages and currents that can degrade the performance of an electrical system. They do not heat well and can degrade power quality. Harmonic voltage analysis is a mathematical technique for forecasting potential resonances and harmonic distortion degrees.

Harmonic voltage analysis is a mathematical approach that uses data to anticipate probable resonances and levels of harmonic distortion. AC variable frequency drives, DC drives, fluorescent light ballasts, and computers are examples of devices that introduce harmonic frequencies to the electrical system. When the harmonic voltage and current levels are high, the likelihood of equipment failure is considerable. Therefore, it is essential to study and evaluate harmonics at the appropriate moment. Current harmonic limitations in 415-volt systems are 5%, with 4% of harmonics being odd and 2% even.

Harmonic Distortion Effects:

International high voltage and alternating current.
Equipment failure and destruction because of severe voltage distortion.
An increase in the quantity of internal energy in components results in increased fragility and a shortened lifespan.
Faults that trigger the tripping of branch circuit breakers.
Error of measurement.
Explosions and fires in wiring and distribution systems.
Failure of generators.
The declining system power factor.
Installation and utility expenses are expensive.
Reduced productivity.
There is no need for unneeded downtime or driving around.
Use of larger engines.

Harmonic issues are uncommon, but when they do occur, they tend to reduce the power system’s dependability, quality, and efficiency. Therefore, it is essential to study and evaluate harmony.

Protection from voltage and current harmonics
Variations in frequency are constrained.
Current and voltage that is out of sync.
Improve power factor analysis and maintain a value near one.
Regulates voltage fluctuations.

Harmonic investigation and analysis will assist in determining what may be causing and what may be causing power quality issues. This will aid in avoiding harmonics-related design issues and reduce the likelihood of undesirable outcomes

Harmonic Study and Analysis Workflow at Carelabs:

Highlight the nonlinear loads, capacitor banks, and lengthy medium-voltage cables on the single-line schematic of an electrical circuit.
Find the point of connection (PCC).
Determine which system buses inside the facility are susceptible to harmonic distortions. Get harmonics information for all nonlinear loads.
Obtain vital information on the voltage and current harmonics at the selected PCC, including the maximum and minimum short circuit fault levels and the harmonic levels permitted in the UK.
ETAP is used to do a harmonic analysis of the electrical network.
Determine the total and individual values of voltage and current wave distortion at the buses and PCC.
Draw the spectrum of frequency for the harmonics.
If the levels of harmonic distortion exceed what is permissible, a remedy is offered and implemented.
After applying the countermeasure, rerun the analysis.

Carelabs Service Advantages:

If background harmonics have previously been measured, the second step consists of higher ratings.

If the backdrop is less than 25%, stage 2 allows the converter size to vary based on the fault level and kind of converter if the background is less than 25%.
If the backdrop is between 25 and 75 percent, the above converter ratings might be reduced by 50 percent.
For the upper backdrop, a comprehensive harmonic analysis is conducted.
