Analysis of Power Quality in Greece
Care Labs analyses power quality for businesses all over Greece. Our goal is to protect your electrical installations, electrical equipment, and appliances from any problems caused by power supply fluctuations.
Many businesses, as well as an increasing number of private customers, now use data collection, monitoring, and instrumentation equipment that is highly susceptible to power supply fluctuations. While most electrical products are designed to withstand certain supply variations, very few are designed to withstand the voltage fluctuation spectrum that is a common feature of distributed electricity.
Professional experts from Care Labs will help you resolve power quality issues in the areas of equipment installation, control, protection, and power conditioning.
Power Quality Analysis's Goal:
- The assessment of inconsistencies in the electrical system and the load.
- Evaluating the work environment in order to improve simulation methods for providing power quality solutions.
- Predicting the operation and efficiency of load equipment
- Increase the power factor and reliability of the machine.
- Avoid excessive energy consumption.
- To avoid breakdowns and disruptions.
- Reducing power quality anomalies like harmonics, spikes, and transients.
- Aid in the prevention of voltage/frequency surges and PLC hang-ups.
- To avoid, among other things, transformer overheating, capacitor explosion, and nuisance tripping.
- Significantly reduce utility bills
- Extend the life of the electrical network and its components.
- Examine electrical equipment to ensure that it can withstand variations.
Power Quality Analysis is Required in Greece:
All electrical networks experience supply interruptions, which are more common when power lines are damaged by storms, natural disasters, or accidents. Power supply fluctuations are completely normal. Fluctuations, disturbances, and distortions in the characteristics of power supplied by an electricity network fall into three categories:
1. Frequency deviations occur when a frequency exceeds its natural frequency range.
2. Voltage disturbances occur when the voltage shape is preserved but the voltage amplitude exceeds the normal range.
2.1 Voltage sag (dip) and voltage swells of up to one minute duration are examples of short-duration variations.
2.2 Long-duration fluctuations include under voltages and over voltages that last more than one minute.
2.3 Unbalanced voltage – occurs when the load is unevenly distributed across the phases, causing significant heating of the equipment.
2.4 Voltage differences between neutral and earth
3. Disturbances caused by distortion – when the voltage shape is not uniform or sinusoidal.
3.1 Waveform distortions: Harmonics and inter-harmonics cause device heating, increased losses, inefficient power consumption, and resonance problems.
3.2 Transients that last less than one-tenth of a second, but are capable of degrading switch contact surfaces, inducing inefficiency in the system, and leading to premature failure of motor drives and control.
What Is Included in Power Quality Analysis?
Different approaches are required to identify various power quality disturbances; a few of these approaches are:
- Harmonic Analysis: The use of computer algorithms to identify and predict potential harmonic problems, as well as reduction techniques, is involved in harmonic analysis.
- Surge and Transient Analysis: This study will identify transients and surges.
- Voltage Dips and Swells Analysis: This analysis would track the short-term drop and rise in voltage, as well as its value and path.
- Analysis of Reactive Power The preferred reactive power at the distribution and load ends will be determined by this analysis.
- Captive Power Analysis: This research would quantify and synchronize captive power in order to meet demand while lowering energy surcharges and fuel consumption.
- Load Flow Analysis: This study forecasts power flow magnitudes, power factors, voltage levels, and losses in system branches based on the defined operating conditions.
