Series Resistance: The resistance in series with the capacitor limits the inrush current.
Show Your Love: The Inrush Calculator is a valuable tool used in electrical engineering to estimate the initial surge of current when an electrical circuit or device is turned on. This surge, known as inrush current, occurs due to the sudden demand for electrical power when capacitors charge or due to the magnetizing of inductors.
Experience has shown that inrush currents of a single isolated bank normally range from five to 15 times the normal capacitor current. Transient frequencies due to isolated capacitor bank switching generally fall in the 300 Hz to 1000 Hz range.
In determining the inrush current magnitude and frequency of a two-step capacitor bank refer to Figure 2 and Equations 5 through 10. It is important to remember that the inductance, Leq, is the total inductance, in micro-henry, from the terminal of one capacitor bank to that of the other capacitor bank.
The magnitude and frequency of this inrush current is a function of the following: It is assumed that the capacitor bank is discharged prior to energization. This assumption is reasonable, as capacitor units are fitted with discharging resistors that will discharge the capacitor bank. Typical discharge times are in the order of 5 min.
Inrush current, also known as surge current, is the initial, high-magnitude current that flows into an electrical device when it is first turned on. This surge is typically caused by the charging of capacitors, magnetization of transformers, and the initial resistance of inductive components.
