Harmonic Study and Analysis

In addition to thorough harmonic research and analysis, CareLabs‘ electrical installation services also involve safety inspections, testing, calibration, and certification. To make sure that your electrical safety program is up to date, compliant, and thorough, trained professionals will evaluate harmonic threats, training programs, paperwork, and personal protective equipment (PPE).

CareLabs can identify harmonics early on and take the required steps to lessen their impact, ensuring the equipment’s safety. Inefficiency in the electrical system may be caused by harmonic voltages and currents. They have the ability to lower the quality of the power and produce extraneous heat. A mathematical method for determining potential resonances and levels of harmonic distortion is called harmonic voltage analysis. Based on gathered data, harmonic voltage analysis is a mathematical method for identifying potential resonances and harmonic distortion levels.

Harmonic frequencies are added to the electrical system by nonlinear electrical switching equipment such AC variable frequency drives, DC drives, fluorescent lights, computers, and so on. When harmonic voltage/current levels are high, a lot of equipment can fail. As a result, harmonic analysis and study must be done as soon as possible. Currently, there are 5% harmonic limits in 415 voltage systems, with 4% odd harmonics and 2% even harmonics.

Effects of Harmonic Distortion:

Charged with controlling high voltage and flowing current.
Excessive voltage distortion damages and destroys electronics.
The branch circuit breaker trips owing to a malfunction, the accumulation of internal energy in components causes component degradation and a decreased lifespan.
Measurements of error
Explosions and flames inside the wiring and distribution system
Generator failures cause power outages
An erosion of the system power factor
The cost of installation and utilities is prohibitive.
Due to excessive travel and downtime, productivity is declining.
Use of more powerful engines

Harmonic problems are incredibly rare, but when they do happen, they significantly affect the reliability, power quality, and efficiency of the power system. Thus, harmonic research and analysis are crucial.

It offers defense against harmonics in voltage and current.
Frequency variation is limited.
Inconsistent current and voltage
Enhance power factor analysis and keep the value close to one.
Variations in voltage are managed.

By shedding light on the likely causes and implications of power quality problems, harmonic research and analysis can help designers avoid harmonic-related challenges and lessen the chance of unanticipated outcomes.

CareLabs' Harmonic Analysis and Research Workflow:

Highlight accessible nonlinear loads, capacitor banks, and long medium voltage cables on the electrical one-line diagram.
Find the PCC (common point of connection)
Identify the facility’s system buses that are prone to harmonic distortions.
For all nonlinear loads, gather harmonics information.
Obtain crucial data on the maximum and least levels of short circuit faults and harmonic values for the selected PCC. This data is also important for understanding voltage and current harmonics.
The electrical network is subjected to harmonic analysis using ETAP.
Calculate the bus and PCC voltage and current wave distortion values, both collectively and individually.
If harmonic distortion levels are more than the permissible limits, a suitable mitigation strategy is developed and put into place.
After putting in the mitigation strategy, run the analysis once again.

Benefits of the CareLabs Service

The Stage 2 values are higher if background harmonics have already been detected.

If the backdrop is less than 25%, Stage 2 allows altering the converter size based on fault level and converter type.
Converter ratings of half the amount mentioned above are allowed if the backdrop is between 25% and 75%.
A comprehensive harmonic analysis is done for the top background.
