The ability of a device to use the energy supplied to it is called power quality. Power quality problems cause excessive energy consumption and degradation, high maintenance costs, direct financial consequences, capacity losses, irreversible downtimes and resources, equipment instability and failures. Every organization must assess energy management and all energy management programs must include an assessment of power quality. CareLabs offers a variety of services to solve energy-related problems. Based on our knowledge, we provide high-quality research and analytical services.

Power Quality Problems

Compared to reliability, power supply quality is a more complex and subtle indicator. The suitability and compatibility of the power supply is more important than the availability of power.

Fluctuations in power quality can be divided into two groups:

Interruptions

Disturbances occur when there is a voltage or current deviation. Transient voltages can be detected when the peak value exceeds a certain threshold. RMS voltage fluctuations, including dips, surges, and interruptions, can be recognized if the RMS variation is greater than a predetermined threshold.

Changes in steady state conditions:

RMS voltage fluctuations and harmonic wave distortion are two examples of steady-state changes. To test these variations, it is necessary to measure voltage and current over time. An average distortion level of 95% is unlikely to be exceeded and other analysis methods are used to represent that sample data most effectively during the voltage distortion period.

These are some factors that affect supply quality:

Voltage stability
Supply frequency
Power drops
Voltage spikes
Instantaneous voltages
Harmonic changes
RF rating

Most of these elements are difficult to identify. Checking this often requires special test tools and must be done by trained technicians or engineers.

Steady State Voltage:

In response to load changes and other system events, the steady state voltage levels of an electrical system often fluctuate. Voltage levels often tend to drop as the load increases. When the load is removed, the voltage levels also increase.

Voltage Unbalanced:

This refers to a change in phase angle offset or three-phase input value. It can also be affected by unbalanced loads and unbalanced circuit resistances. This leads to equipment failure, thermal effects and reduced efficiency.

Voltage Fluctuations:

A voltage sag is a short-term drop in RMS supply voltage lasting up to a minute. Voltage swell is a short-term increase in RMS supply voltage that occurs above a threshold of 0.5 cycles and 1 minute.

Supply Frequency:

Supply frequency is the frequency with which the supply voltage waveform changes. The National Electricity Market Management Company, or NEMMCO (National Electricity Market Management Company), sets frequency standards for the national electricity market. Frequency standards are decided by the local power generation authority outside the national electricity market.

Harmonic Distortion

This distortion of the source voltage or current waveform is periodic and constant. Excessive losses, flashing lights, malfunctions, radio interference, motor vibration and deficient performance of sensitive equipment can all be caused by excessive harmonics.

Power quality analysis procedure in CareLabs:

Both the on-site assessment and the purpose of the power quality survey were explained.
Continuing the investigation, make a one-line diagram of the entire electrical system.
A powerful analyzer is attached to several points of the distribution head, which collects data from each individual system.
The description of the line diagram of the distribution system should be continued.
In addition to reviewing and analyzing the collected data, additional analyzes are performed. Submit
