This paper discusses design considerations and system implications for Eaton's Cooper PowerTM series externally fused, internally fused or fuseless capacitor banks.
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.
The main reason for a burning or even exploding capacitor bank is the liquid-filled capacitors, or the plastic parts that are combustible. If the temperature rises, the capacitor can cause a fire, a life-threatening situation, and economic loss.
This heating, provoked by the losses of the components that are placed inside, produces an increase of the temperature that should be lower to the maximum working temperatures of the equipment and capacitors.
Bank stability for a fuseless capacitor bank is similar to that of an externally fused capacitor bank and defined by shorted series sections, internal to individual capacitors. The voltage on the remaining series sections in the string should not exceed 110% of its rated voltage.
Therefore, this article proposed an analytical thermal modeling method with high-resolution for the capacitor bank, considering the thermal coupling effect between individual capacitors, as well as different cooling conditions and the heat variation caused by ESR aging.
