The ability of equipment to use the energy supplied to it is referred to as power quality. Power quality issues lead to excessive energy usage and bills, high maintenance costs, direct economic repercussions, output loss, irrecoverable downtime and resources, equipment instability, and failure. Any organization must assess energy management, and any energy management program must include an assessment of power quality. CareLabs provides a range of services to address various energy-related issues. Based on our expertise in this area, we offer high-quality research and analytical services.

Quality Issues with Electricity:

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

Variations in power quality may be divided into two groups:

Interruptions:

Disturbances occur when there is an anomaly in the voltage or current. Transient voltages can be identified when the peak magnitude exceeds a specified threshold. When the RMS variation exceeds a certain limit, RMS voltage variations such as sags, surges, and interruptions can be identified.

Changes in steady-state circumstances:

RMS voltage fluctuations and harmonic wave distortion are two instances of steady-state changes. To sample these variations, measurements of voltage and current over time are required. The average distortion level, which is 95% unlikely to be exceeded, and other analysis techniques are used to portray this sampled data most effectively as a voltage distortion amount across time.

These are some of the elements that influence supplier quality:

Voltage constancy
Delivery frequency
Power drops
Spikes in voltage
Momentary voltages
Harmonic alterations
Estimation of radiofrequency

Most of these elements are difficult to identify and see. Its inspection often needs specialized testing tools, and it needs to be done by trained technicians or engineers.

Constant Voltage:

In reaction to load changes and other system occurrences, the electrical system’s steady-state voltage levels fluctuate often. Voltage levels often tend to drop as the load rises. When a load is removed, voltage levels also increase.

Voltage Unbalanced:

It alludes to a change in the phase angle displacement or three-phase supply value. Unbalanced loads and unbalanced circuit impedances can also contribute to it. It results in equipment failure, heat effects, and efficiency loss.

Voltage Variations:

RMS supply voltage dips last up to one minute during voltage sags. Short voltage swells occur between 0.5 cycles and 1 minute in RMS supply voltage.

Frequency of Supply:

The supply frequency is the frequency at which the supply voltage wave alternates. The National Electricity Market Management Company, or NEMMCO, establishes the frequency standards for the National Electricity Market. Frequency standards are decided by the local generating authority outside of the National Electricity Market.

Deformation of Harmonics

This distortion of the source voltage or current waveform is periodic and constant. Extra losses, flickering lights, malfunctions, radio interference, motor vibrations, and poor performance of sensitive equipment can all be brought on by excessive harmonics.

Power Quality Analysis Procedure at CareLabs:

Both the on-site evaluation and the power quality survey’s goal are made clear.
As you continue your inquiry, create a one-line diagram of the whole electrical system.
A power analyzer is attached at numerous points along the distribution end to collect data from each distinct system.
The line diagram’s depiction of the distribution system should be continued.
Additional analysis is done in addition to looking through and analysing the collected data.
Submitting a report and solution suggestions
