Harmonic Study and Analysis

CareLabs‘ electrical installation services include detailed harmonic analysis and research as well as safety inspections, testing, calibration, and certification. Trained experts will assess harmonic hazards, training programs, documentation, and personal protective equipment (PPE) to ensure that your electrical safety program is current, compliant, and comprehensive.

CareLabs can detect harmonics early and take the necessary actions to reduce their influence, assuring the safety of the equipment. Harmonic voltages and currents can lead to electrical system inefficiency. They have the capability to reduce electricity quality and generate excessive heat. Harmonic voltage analysis is a mathematical technique for identifying possible resonances and degrees of harmonic distortion. Harmonic voltage analysis is a mathematical technique for determining potential resonances and harmonic distortion levels based on acquired data.

Equipment for nonlinear electrical switching, such as AC variable frequency drives, DC drives, fluorescent lights, computers, and so on, introduce harmonic frequencies to the electrical system. Many pieces of machinery can malfunction when harmonic voltage/current levels are high. Harmonic analysis and research must be completed as quickly as feasible. 415 voltage systems currently have 5% harmonic limitations, with 4% odd harmonics and 2% even harmonics.

Harmonic Distortion's Effects

Entrusted with managing flowing current and high voltage.
Electronics are damaged and destroyed by excessive voltage distortion.
Due to a malfunction, the branch circuit breaker trips, and the buildup of internal energy in components results in component deterioration and a shorter lifespan.
Error measurements
Inside the wiring and distribution system, explosions, and flames
Power outages are caused by faulty generators.
A decrease in system power factor
Installation and utility costs are exorbitant.
Productivity is decreasing as a result of excessive travel and downtime.
Usage of stronger engines

Harmonic issues are extremely uncommon, but when they do arise, they have a substantial impact on the system’s dependability, power quality, and efficiency. Research and study of harmonics are so essential.

It provides protection against voltage and current harmonics.
Variation in frequency is minimal.
Uneven voltage and current
Improve power factor analysis and maintain a value around one.
Voltage variations are controlled.

Harmonic research and analysis can assist designers in avoiding harmonic-related obstacles and reducing the possibility of unexpected results by illuminating the likely causes and consequences of power quality issues.

Harmonic Analysis and Research Workflow at CareLabs:

On the electrical one-line diagram, draw special attention to reachable nonlinear loads, capacitor banks, and lengthy medium voltage connections.
Locate the common point of connection, or PCC.
Determine which system buses in the building are susceptible to harmonic distortions.
assemble harmonics data for all nonlinear loads.
Obtain critical information about the Australian-allowed harmonic values, the maximum and minimum short circuit fault levels, and the selected PCC. Additionally crucial for understanding voltage and current harmonics is this data.
ETAP is used to do a harmonic analysis on the electrical network.
Determine the voltage and current wave distortion values for the bus and PCC, both collectively and individually.
An appropriate mitigation plan is created and implemented if harmonic distortion levels exceed the allowable limits.
Run the analysis again after adding the mitigation approach.

Advantages of CareLabs' Service

In cases when background harmonics have previously been identified, the Stage 2 values are greater.

Stage 2 permits changing the converter size based on fault level and converter type if the background is less than 25%.
If the background is between 25% and 75%, converter ratings of 50% of the quantity specified above are acceptable.
For the top backdrop, an extensive harmonic analysis is performed.
