Harmonic Study and Analysis

Find Out What It's All About

CareLabs provides electrical installation services including safety inspections, testing, calibration, and certification in addition to complete harmonic research and analysis. Professionals will assess harmonic dangers, training program, paperwork, and personal protective equipment (PPE) to verify that your electrical safety program is up-to-date, exhaustive, and compliant. CareLabs is able to identify harmonics early on and take the required measures to mitigate the impact of harmonic distortions to ensure the safety of the equipment. 

What is Involved

In an electrical system, harmonic voltages and currents can result in inefficiency. They emit inefficient heat and may degrade the quality of the generated electricity. A mathematical approach for forecasting potential resonances and harmonic distortion levels is harmonic voltage analysis. Based on actual evidence, harmonic voltage analysis is a mathematical approach for estimating potential resonances and harmonic distortion levels. Harmonic frequencies are introduced into the electrical system by nonlinear electrical switching equipment such as AC variable frequency drives, DC drives, fluorescent lights, and computers. High voltage/current harmonic levels present a substantial danger of equipment failure. Therefore, a timely harmonic investigation and analysis is required. Current harmonic limitations for 415-volt systems are 5%, with 4% odd harmonics and 2% even harmonics.

Harmonic Distortion Has the Subsequent Consequences:

  • Circulating current and high voltage are produced.
  • Equipment failure and damage because of substantial voltage distortion
  • Fault-initiated branch circuit breaker tripping
  • Deviation measurement
  • Fires and explosions in the wiring and distribution system
  • Power outages resulting from generators
  • A decline in the power factor of the system
  • Expensive installation and energy expenses
  • Larger size motor

Harmonic issues are exceedingly rare, but when they do arise, they tend to degrade the power system’s dependability, quality, and efficiency. Consequently, harmonic investigation and analysis are needed. 

  • Provides protection from voltage and current harmonics
  • Restriction of frequency variation
  • Voltage and current imbalance
  • Enhancement of power factor analysis and maintenance of a result close to one.
  • Regulates voltage fluctuations.

Harmonic research and analysis will shed light on the likely origin and impact of power quality issues, helping the avoidance of harmonic-related difficulties during the design phase and lowering the chance of unanticipated effects. 

Harmonic Analysis and Research Workflow at CareLabs:

  • Highlight on the single-line diagram the available nonlinear loads, capacitor banks, and lengthy medium-voltage cables.
  • Identify which in-plant system buses are sensitive to harmonic distortions.
  • Identify the common connecting point (PCC).
  • Gather harmonics information for all nonlinear loads.
  • Acquire vital data on voltage and current harmonics at the selected PCC, including the maximum and lowest short circuit fault levels and the permitted harmonic values in netherlands.
  • Conduct harmonic analysis on the electrical network using ETAP.
  • Compute the global and discrete current and voltage distortion values at the buses and PCC.
  • Draw the spectrum of harmonic frequencies.
  • If harmonic distortion levels surpass permissible limits, an appropriate mitigation strategy is devised and implemented.
  • After incorporating the countermeasure, perform the analysis.

CareLabs's Service Benefits:

If background harmonics have previously been measured, the second stage is comprised of higher values. 

  • If the backdrop is less than 25%, stage 2 permits variable converter size depending on fault level and converter type if the background is less than 25%.
  • If the backdrop is between 25 and 75 percent, only 50 percent of the permitted converter grade may be utilized.
  • A comprehensive harmonic analysis is conducted in the foreground.
