How to Conduct a Power Quality Analysis in Korea?
Power quality describes how well a piece of equipment can use the energy that is provided. Problems with power quality result in excessive energy use, high energy bills, expensive maintenance, immediate economic effects, lost productivity, downtime, irreplaceable resources, and unstable or dysfunctional equipment. Any organization must take energy management into consideration, and any energy management program must address power quality. CareLabs provides a variety of services that deal with a variety of energy-related issues. Based on our knowledge in the sector, we provide services for investigating and analysing power quality.
Electricity Supply Issues:
A more intricate and nuanced metric than dependability is power supply quality. Whether or if there is adequate supply is immaterial. Instead, the question is whether the source can be used.
There are two types of power quality changes:
Disruption:
A disruption might occur due to an improper voltage or current. A transient voltage’s peak value can be computed after it crosses a particular threshold. The RMS voltage fluctuates with dips, swells, and pauses when the RMS variation exceeds a specific threshold.
Differences from the constant:
The RMS voltage and harmonic wave distortion are two examples of steady-state changes. To track these changes, voltage and current must be monitored throughout time. The magnitude of voltage distortion over time is best represented by this sample data. The average distortion level may then be examined using several techniques; it is 95% unlikely to be surpassed.

The following are a few factors that influence supplier quality:
- Constant voltage
- The regularity of its accessibility
- Voltage declines
- Voltage peaks
- Variations in voltage
- Changes in the harmony
- Estimated radio frequency
Most of these items are difficult to recognize and observe. They are often measured using specific testing equipment, and only skilled employees or engineers should do the tests.
Constant Voltage:
Due to load and other system events, the steady-state voltage levels of an electrical system are constantly changing. Voltage levels often decrease as the load increases. Like this, when a load is removed, the voltage increases.
Unbalanced Voltage:
It is a variation in the three-phase supply’s value or a shift in the phase angle. Unbalanced loads and unbalanced circuit impedances might also be the culprits. It raises the temperature of objects, damages equipment, and lessens their efficiency.
Voltage Changes:
Rapid reductions in RMS supply voltage known as “voltage sags” can last anywhere between 0.5 and 1 minute. Voltage swells are short, above-the-0.5-to-1-minute threshold rises in the RMS supply voltage.
How Often Are They Advertised:
The pace at which the voltage waves change is known as the supply frequency. The management of the National Electricity Market is the responsibility of NEMMCO (National Electricity Market Management Company). The local production authority sets the frequency standards outside of the National Electricity Market.
Harmonic Changes:
It is a periodic shift in the supply voltage or current pattern. Increased losses, malfunctions, radio interference, motor vibrations, and sensitive equipment that is not as effective can all be caused by more harmonics.
Carelabs Uses the Following Method to Assess Power Quality:
- The aim of the power quality survey and the results of the on-site evaluation are both reported.
- Create a one-line schematic of the entire electrical system as you go along with your investigation at the distribution end, many connections to power analyzers are built to collect data from each individual system.
- Maintaining the one-line diagram’s representation of the distribution network.
- Additional analysis is done in addition to looking through and analysing the data that was gathered.
- Submitted a report with recommendations
You may get guidance from our highly educated experts on how to address power quality issues. If you do a thorough inspection and analysis, your system’s power quality will be at its best. If you have any questions concerning our power quality analysis service, please get in touch with us.
