Why is a capacitor bank important?
the computer plays a vital role in all parts of life and industry, especially in the power system applications. The capacitor bank is considered as one method to improve the power factor (PF) and reduce the line current and since the equipment of the analysis cannot be provided always.
What happens if a capacitor peaks 3 times rated voltage?
In low voltage networks, inadmissibly high voltage peaks of up to 3 times the rated voltage can occur through switching operations. If these loads lead to flashovers in the dielectric, the self-restoring efect is triggered. The capacitor remains fully functional as this happens.
When are series capacitors effective?
Series capacitors are very effective when the total line reactance is high. Series capacitors are effective to compensate for voltage drop and voltage fluctuations. Series capacitors are of little value when the reactive power requirements of the load are small.
