LETS DISCOVER MORE
In addition to safety inspections, testing, calibration, and certification, CareLabs’ electrical installation services include extensive harmonic research and analysis. Experts will evaluate harmonic threats, training programs, paperwork, and personal protective equipment (PPE) to verify that your electrical safety program is current, compliant, and exhaustive. To guarantee the equipment’s safety, CareLabs can detect harmonics early on and take the required steps to mitigate their impact. Harmonic voltages and currents inside the electrical system are capable of causing inefficiency. They produce superfluous heat and have the potential to damage electrical quality. Â
Harmonic voltage analysis is a mathematical method for estimating potential resonances and harmonic distortion levels. Harmonic voltage analysis is a mathematical method for evaluating potential resonances and degrees of harmonic distortion based on gathered data. Harmonic frequencies are introduced into the electrical system by nonlinear electrical switching equipment, including AC variable frequency drives, DC drives, fluorescent lights, and computers, among others. When harmonic voltage/current levels are high, there is a significant risk of equipment failure. Therefore, timely harmonic study and analysis is vital. Harmonic limitations in 415 voltage systems are currently set at 5%, with 4% odd harmonics and 2% even harmonics.Â
Effects of Harmonic Distortion:
- Cost associated with controlling circulating current and high voltage.
- Excessive voltage distortion causes equipment failure and damage.
- The buildup of internal energy in components results in component failure and a reduced lifetime.
- Because of a malfunction, the branch circuit breaker trips.
- 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 is diminishing.
- Idle time and unneeded travel
- Utilization of larger engines
Harmonic problems are exceedingly uncommon, but when they do arise, they significantly impact the power system’s reliability, power quality, and efficiency. Therefore, harmonic analysis and study are essential.
- It provides voltage and current harmonics prevention.
- Limitation of frequency variance
- Uneven current and voltage
- Enhance power factor analysis and keep the value close to one.
- Voltage fluctuations are regulated.
Harmonic research and analysis will shed insight on the causes and effects of power quality concerns, facilitating the avoidance of harmonic-related problems during the design phase and decreasing the possibility of unexpected outcomes.Â
CareLabs' Harmonic Analysis and Research Workflow:
- Highlight available nonlinear loads, capacitor banks, and lengthy medium voltage cables on the electrical one-line diagram.
- Determine the common connection point (PCC)
- Determine which system buses are prone to harmonic distortions inside the facility.
- Gather data on harmonics for all nonlinear loads.
- Obtain crucial information on voltage and current harmonics at the selected PCC, including the maximum and minimum levels of short circuit faults and the maximum harmonic values permitted in Australia.
- ETAP (Electrical Transient Analyzer Program) is used for electrical network harmonic analysis.
- Calculate the total and discrete values of current and voltage wave distortion at the buses and PCC.
- Create a graph illustrating the harmonic frequency spectrum.
- If harmonic distortion levels surpass acceptable limits, a suitable mitigation strategy is developed and implemented.
- After implementing the countermeasure, rerun the analysis.
Advantages of Service from CareLabs:
If background harmonics have been previously measured, Stage 2 results will be larger.
- If the background is less than 25 percent, Stage 2 let’s alter the size of the converter based on the fault level and the kind of converter.
- If the backdrop is between 25% and 75%, it is appropriate for the converter rating to be half of the amount mentioned above.
- For the top background, a comprehensive harmonic analysis is performed.
