Harmonic Study and Analysis
In addition to a thorough investigation and analysis of harmonics, CareLabs provides electrical installation services that include electrical safety inspections, testing, calibration, and certification. To make sure that your electrical safety program is current, compliant, and comprehensive, experts will examine harmonic dangers, training materials, paperwork, and personal protective equipment (PPE). To protect the apparatus, CareLabs is able to recognize harmonics early and take the required measures to lessen their influence.
Electrical systems may lose efficiency when there are harmonic electric voltages and currents. They have the ability to reduce the quality of the electricity and create wasteful heat. A mathematical technique for foretelling resonances and harmonic distortion levels is harmonic voltage analysis. Using empirical data, harmonic voltage analysis is a mathematical technique for forecasting possible resonances and harmonic distortion levels. Nonlinear electrical switching components, such as AC variable frequency motors, DC actuators, fluorescent lighting, and computers, add harmonic frequencies to the electrical system. The danger of equipment failure is significantly increased by high voltage/current harmonic levels. Thus, it is crucial to carry out a quick harmonic analysis and investigation. For 415-volt systems, the current harmonic limitations are 5%, with 4% odd harmonics and 2% even harmonics.
- Accountable for both high voltage and current flow.
- Equipment failure and destruction because of substantial voltage distortion
- There is a decrease in component lifetime and an increase in component failure because of an increase in internal energy.
- Branch circuit breakers turn on when a problem arises.
- Measuring error
- Fires and explosions in electrical and distribution networks
- Generator malfunctions
- System power factor declines
- Expensive installation and utility costs
- Decrease in productivity
- Inattention and unnecessary driving
- Use of more powerful motors
Harmonic issues are extremely rare, but when they do occur, they tend to reduce the power system’s dependability, quality, and efficiency. As a result, harmonic research and analysis are essential.
Harmonic Distortion's Effects:
- Safeguards against harmonic current and voltage
- Constrained frequency variation
- Variability of voltage and current
- Improve power factor analysis and keep the value around one.
- Controls the peaks and troughs of the voltage
By avoiding harmonic-related concerns during the design phase and lowering the chance of unexpected results, harmonic research and analysis will assist shed light on the likely origin and impact of power quality issues.
CareLabs' Harmonic Analysis and Research Workflow:
- On the electrical single-line diagram, indicate any potential nonlinear loads, capacitor banks, and long medium-voltage cables.
- Find the point of common coupling, or PCC.
- Identify the facility’s system buses that are prone to harmonic distortions.
- For each nonlinear load, collect harmonics information.
- Obtain crucial data on the maximum and lowest short circuit fault levels for the selected PCC’s voltage and current harmonics.
- Analyze the electrical network’s harmonics using ETAP (Electrical Transient Analysis Program).
- Find the bus and PCC’s overall and individual current and voltage wave distortion values.
- Draw a diagram of the harmonic frequency spectrum.
- If harmonic distortion levels are too high, an appropriate mitigation approach is recommended and put into practice.
- Rerun the research after the mitigation strategy has been put in place.
The Service's Advantages Include:
Higher ratings are utilized in the second step if background harmonics have previously been measured.
- If the background is less than 25%, Stage 2 allows modifying the converter size in accordance with the fault level and converter type.
- The lower half of the converter grade is acceptable if the backdrop is 25% to 75%.
- The higher background has its harmonics thoroughly analyzed.
To guarantee that personnel is easily reachable in case of a regular or urgent emergency, CareLabs has staff members stationed in several places.
