Abstract: The protection of shunt power capacitor banks and filter capacitor banks are discussed in this guide. The guidelines for reliable application of protection methods intended for use in many shunt capacitor bank designs are included. Also, a detailed explanation of the theory of unbalance protection principles is provided.
Series capacitor bank component and bank duty cycle ratings, equipment insulation levels, protective functions, component testing, instruction books, nameplates, and safety are covered in this standard Scope: The scope is a standard for series capacitor banks that are connected in series with the utility transmission system.
The unbalance protection should coordinate with the individual capacitor unit fuses so that the fuses operate to isolate the faulty capacitor unit before the protection trips the whole bank. The alarm level is selected according to the first blown fuse giving an early warning of a potential bank failure.
The objective of the capacitor bank protection is to alarm on the failure of some minimum number of elements or units and trip on some higher number of failures. It is, of course, desirable to detect any element failure. II. ELEMENT AND UNIT FAILURES EXAMINED
I. INTRODUCTION Capacitor banks are designed with many configurations to meet system design constraints, and the protection engineer must be prepared to protect any of these configurations. The inputs available to the relay are voltage and current, with the instrument transformer location determined by the bank configuration.
