Voltage variations refer to changes in electrical voltage levels within a power system. These fluctuations can occur due to various factors, such as changes in electrical load, equipment malfunctions, or disturbances in the power supply. Maintaining stable voltage levels is crucial for the proper functioning of electrical devices and systems. In electrical engineering, voltage variations can be categorized into two main types: transient and steady-state variations. Transient variations are short-lived spikes or dips in voltage, while steady-state variations are more prolonged changes. Both types can impact the performance and lifespan of electrical equipment, making monitoring and management essential for reliable power delivery.
