Ideally, the best electric power supply would be a constant sinusoidal voltage, current magnitude and frequency waveform. However, because of the non-zero impedance of the power supply, of the various types of loads that is connected to it and of other phenomena like transients and power outages, the reality is often different. The Power Quality of any system supply expresses to which degree a practical supply resembles the ideal supply.
If the system supply power quality is good, then the connected loads will run efficiently and satisfactory. Facility’s running costs and carbon footprint will be minimal.
If the system supply power quality is bad, then all the connected loads will fail or will have a reduced lifetime, and reduction in the efficiency of the electrical system. Facility’s running costs and its carbon footprint will be high and operation may not be possible at all.
Care Labs provide several services for electrical installations all over Mexico. We are offering comprehensive power quality analysis service for all types of buildings.
Cost of Poor Power Quality:
Poor power quality can be defined as any incident related to the electrical installation that could results in a financial loss. Consequence of poor power quality include:
- Unexpected power supply interruptions (circuit breaker tripping, fuse blowing).
- Equipment failure or malfunctioning
- Overheating of equipment (transformers, motors), that leads to their lifetime reduction.
- Damage to sensitive components and electronics (PC’s, production line control systems).
- Electronic communication interferences.
- Increase of system losses.
- Need to oversizing the overall system to cope up with additional electrical stress with resulting increase of system and overall running cost and associated increased carbon footprint.
- Penalties imposed by authorized body for the system pollutes the main network too much.
- Refusal of new system connection because the system would pollute the network.
- Health & safety problems and reduced efficiency of working personnel
Steps in Power Quality Analysis are:
- Program start-up, orientation deals with objective of the survey is detailed with the power quality study tools, parameters, safety precautions, etc.
- Proceed with actual single-line diagram of the electric installation of the facility.
- Continue to the assessment down into the distribution network following the single-line diagram.
- Inspecting and assessing the facility and check whether any major issues in the power supply. This part includes measuring various parameters using various measuring tools, that can help you find and provide data in terms of power quality problems.
- Multimeters, flicker meters, infrared detectors, disturbance analyzers, and harmonic analyzers help in identifying the associated power quality problems and provide necessary data to isolate the problem
Various parameters of power quality measured includes:
- Monitoring active and reactive Power
- Monitoring instantaneous power factor
- Monitoring quantities- voltage, current
- Monitoring duration of steady and disturbance performance.
- Threshold levels differentiate between steady and disturbed state.
- Sampling of waveform
Power quality analyzer is connected at a various location of the electrical distribution network end of the main circuit breakers that is responsible to regulate incident energy levels.
- Obtaining power quality measurements of various electrical parameters.
- Analyzing the measured data to predict and evaluate all possible power quality issues that might occur at the current operating condition and faulty conditions.
- Recommending measures to minimize/ mitigate power quality issues based on the observations.
- Preparation of draft report
- Review of the authorities’ draft report
- Preparation of final report
The final report offered by Care Labs contains the executive summary, observations, and recommendations along with graphs and drawings (if any) inscribed by our professionals. The report will also be provided to you in a digital format.
