Reliability Calculations for Capacitor Banks
IEEE Power Engineering Review, 1983The reliability of high voltage power capacitor banks has been analyzed using a statistical model based on the failure intensity of the single capacitor element. The expected lifetime of the bank is obtained by computer simulation of element failure sequences leading to bank failure according to a preselected criterion.

IEEE Transactions on Power Delivery, 1992
A fuseless capacitor bank construction is described. Before the first fuseless capacitor bank, engineering tests were performed to ensure that the fuseless concept was sound. Testing of faulted units included: continuous current, capacitor switching, and capacitor losses (power factor).

2007 IEEE 34th International Conference on Plasma Science (ICOPS), 2007
Summary form only given. High voltage capacitor banks may be required to deliver precise amounts of energy to the load. Various industrial and scientific systems including lasers, magnets and flash lamps may require precise and repeatable energy delivery. This paper discusses the design of capacitor banks to meet these requirements.

Protection Of Tuned Capacitor Banks
Conference Record of 2007 Annual Pulp and Paper Industry Technical Conference, 2007The purpose of this paper is to describe several different methods of protection of tuned capacitor banks, and how the relay protection settings for each are determined. Problems with the different schemes are described, and a new protective scheme is proposed.

Connection and protection of capacitor banks
Electrical Engineering, 1950THE FACT that capacitors are built in units of 25 or 15 kilovars for power circuits makes possible variety of groupings of these convenient “building blocks” to form large banks. The arrangement in which the capacitor units are connected in a 3-phase bank and the type of protective arrangement used may influence the cost of the installation; these ...

Protection of large capacitor banks
Review of Scientific Instruments, 1983Large capacitor banks, as used in many pulsed plasma experiments, are subject to catastrophic failure in the event of a short in the output or in an individual capacitor. Methods are described for minimizing the damage and down time caused by such a failure.

Overvoltage protection of capacitor banks
2011 International Symposium on Lightning Protection, 2011The application and effectiveness of MO surge arresters to capacitor banks is discussed. Principle application rules for different configurations are given. The influence of MO arresters with different ratings on voltage and current at the capacitors and at a re-striking circuit breaker respectively is shown and quantified.

Continuous monitoring of a capacitor bank
IEEE Instrumentation & Measurement Magazine, 2001We have developed a prototype system for safety assurance of a capacitor bank by combining application-specific and off-the-shelf surveillance technology for remote monitoring. Traditional surveillance technology passively records facility operations, waiting for an event to trigger a physical audit of the collected information.

A primer on capacitor bank protection
IEEE Transactions on Industry Applications, 2001Capacitor banks are applied in power systems to provide reactive power. The reactive power results in lower current in lines upstream of the bank improving system voltage and power factor and reducing line losses. Capacitor banks can be configured as filters for harmonic reduction.
