feszültségingadozásokra

Feszültségingadozás, commonly referred to as voltage fluctuation or voltage sags/swells, describes a temporary decrease or increase in the voltage level of an electrical power system. These deviations from the nominal voltage can occur for various reasons and can have different impacts on connected equipment.

Voltage sags, also known as voltage dips, are characterized by a sudden and significant drop in voltage that typically lasts for a few cycles to a few seconds. Common causes for sags include short circuits, the starting of large industrial motors, or the activation of heavy loads. During a sag, sensitive electronic equipment may malfunction, reset, or even sustain damage.

Voltage swells, conversely, are temporary increases in voltage above the nominal level. These can be caused by the sudden removal of a large load or by switching operations in the power grid. Swells, like sags, can also negatively affect electronic devices, potentially leading to overheating or premature component failure.

Monitoring and mitigating feszültségingadozás are crucial for maintaining the reliability and longevity of electrical systems and the equipment they power. Techniques such as voltage regulators, uninterruptible power supplies (UPS), and surge protectors are employed to safeguard against the detrimental effects of these voltage variations. Understanding the causes and consequences of feszültségingadozás is essential for engineers and technicians working with electrical power distribution and utilization.
