Overheating of capacitor banks is a common problem in reactive power control systems, and these systems are an essential part of electric distribution and transmission. It may occur due to inadequate ventilation, loose connections, bad design, or the overvoltage during lower demand period.
Stress specific to the protection of capacitor banks by fuses, which is addressed in IEC 60549, can be divided into two types: Stress during bank energization (the inrush current, which is very high, can cause the fuses to age or blow) and Stress during operation (the presence of harmonics may lead to excessive temperature rises).
Capacitor banks are critical components in substations, playing a pivotal role in maintaining power quality and stability within electrical distribution systems. These devices consist of multiple capacitors connected either in series or parallel, functioning as a unified system to store and release electrical energy as required.
As a point of general reference, it is possible for an electrolytic capacitor to heat up even during normal operation, if the capacitor is exposed to ripple currents. This is a situation where the capacitor is rapidly charged and discharged, either partially or completely. For example, on the output of a rectifier, or in a switching power supply.
Storing and Releasing Reactive Power: Capacitor banks store reactive energy when demand is low and release it when needed, smoothing out fluctuations caused by varying loads or intermittent renewable energy sources.
By addressing issues such as lagging power factors and voltage drops, capacitor banks contribute significantly to the efficient operation of electrical grids.
