Indítóáram
Indítóáram, also known as inrush current or starting current, refers to the temporary surge of electrical current that flows into a device when it is first switched on. This phenomenon is particularly noticeable in devices with inductive loads, such as electric motors, transformers, and fluorescent lamp ballasts. When power is applied to these components, their magnetic fields are not yet established, leading to a much lower impedance than when they are operating normally. This low impedance allows a significantly larger current to flow momentarily until the magnetic field builds up and the impedance increases.
The magnitude of the indítóáram can be several times the normal operating current, typically ranging from two
To mitigate the effects of indítóáram, various starting methods are employed. These include soft starters, variable
