A problem in an electrical system caused by any change in voltage, current and frequency should not cause any malfunction or undesirable operation of the user's system. If this is achieved, electrical energy can be said to be of good quality.

The most important factors affecting the quality of electrical energy are the changes in voltage and current values, fluctuations in value and fluctuations. Voltage changes and fluctuations are instantaneous drops in an electrical power system. Generally, the tension will recover within a few seconds. Overvoltage occurs due to insulation errors or excessive reactive power. In an insulated or grounded system, if an insulation fault occurs between phase and ground, the voltage applied to the ground line from the bulk phases may increase to the phase to phase voltage.

Quality energy is only possible with the use of quality materials. In general, energy distribution companies have to supply quality energy. Users also have to take the necessary precautions in order not to disturb the energy quality of the system. If there are non-linear loads in the electrical system, harmonic measurements should be made immediately and the installation should be filtered and input protection reactors should be added in front of non-linear loads.

Today, when the industrial and commercial activities are carried out, electrical energy is the most important input. In an ideal alternating current power system, the generation, transmission and distribution of electrical energy is carried out at certain voltage levels. However, in practice, the necessary conditions are not always fully met. Therefore, the concept of energy quality has gained importance. The concept of energy quality includes all aspects of the amplitude, phase and frequency of the voltage and current waveform in a power circuit.

Factors that cause deterioration of energy quality are sudden interruptions, changes in voltage amplitude and frequency, harmonics and load imbalances. Quality electrical energy must maintain the rated values ​​of voltage, amplitude and frequency at a certain point. Variations in the amplitude of the voltage, interruptions, voltage pulses, distortion of the waveform, frequency changes and three-phase imbalances indicate energy poor quality.
