We achieved this simplicity by working in per-unit values. It is apparent that an unbalance in capacitor bank voltages and currents is a result of a difference between the faulted and healthy parts of the bank. As such, the per-unit voltage or current unbalance is independent of the absolute characteristics of the faulted and healthy parts.
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
CONCLUSION The many variations in capacitor bank design mean there is no one-size-fits-all solution to bank protection. The basic concepts of short-circuit protection and element failure detection remain unchanged, regardless of bank design. We recognize that different protection types are useful for different conditions.
