The term “Power Quality” refers to the degree of conformity of the electrical supply (voltage, frequency and waveform) to pre-established standard specifications. Power Quality is considered optimal when the energy supply guarantees the correct functioning of electrical and electronic equipment, without causing malfunctions, damage or unexpected downtime.
Power Quality control plays a fundamental role in guaranteeing the safety, efficiency and reliability of electricity.
Power Quality electrical disturbances
- Voltage variations: overvoltages, undervoltages and short-term voltage dips.
Voltage sags, spikes and variations damage sensitive electronic equipment, interrupting production and causing data loss. - Phase unbalance: non-uniform distribution of current between the phases of the electrical system.
The non-uniform distribution of current between the phases of the electrical system can cause overheating of the motors, energy losses and reduction of the useful life of the components. - Harmonic disturbances: Distortions of the voltage or current waveform.
They distort the current waveform, causing overheating, energy losses and equipment malfunctions. - Frequency variations: Deviations from the nominal frequency value (in Europe 50 Hz).
Frequency variations cause significant problems for electric motors: incorrect rotation speed, vibrations, excessive noise, for lighting systems: flickering and unstable brightness and for electronic devices: operating errors and system blocking. - Flicker: Rapid fluctuations in voltage level.
These irregular and uncontrolled transients generate operating problems for electronic equipment, compromising their precision, reliability and durability. - Low power factor: Electrical loads draw more reactive power than necessary.
This generates energy losses and possible overload problems. - Voltage dips: very short temporary reduction in nominal voltage.
Voltage sags or SAGs cause malfunctions on electronic control systems which generally lead to data loss, activation of reset loops and even service interruptions. - Lack of voltage: temporary absence of electrical power.
Black out phenomena cause the interruption of service and the consequent shutdown of electrical equipment.
What are the consequences of bad Power Quality?
- Increase in energy costs: energy losses and inefficiency of electrical systems.
- Equipment damage: reduction of useful life and malfunctions.
- Service interruptions: disruptions and loss of productivity.
