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.
Capacitor banks provide an economical and reliable method to reduce losses, improve system voltage and overall power quality. This paper discusses design considerations and system implications for Eaton’s Cooper PowerTM series externally fused, internally fused or fuseless capacitor banks.
If the capacitor bank is balanced and the system voltage is balance the neutral voltage will be zero. A change in any phase of the bank will result in a neutral or zero sequence voltage. VT and an overvoltage relay with 3th harmonic filter. It is simple but suffers in presence of system voltage unbalances and inherent unbalances.
A large capacitor bank is designed to provide a peak current of range 10-15MA at the rate of 10 12 A/s. A single spark gap cannot supply such a high current. Spark gaps with low jitter are used in parallel for high current applications. Generally, the design of a capacitor bank needs a separate spark gap.
The capacitor banks have high power density, and low ESR, are compact and have long-life cycles. It is connected with storage batteries to enhance the life cycle of the battery. The power quality can be enhanced in the power system. The ride-through capability can also be provided by the capacitor bank in the regulated speed drives.
Shunt capacitor banks are used to improve the quality of the electrical supply and the efficient operation of the power system. Studies show that a flat voltage profile on the system can significantly reduce line losses. Shunt capacitor banks are relatively inexpensive and can be easily installed anywhere on the network.
