The objective of this patent is to describe novel methods and device systems for detecting the fault-cleared state in a shunt compensated transmission line. The methods are applicable in all types of transmission line types and faults, in any type of reclosure mechanism, and can be implemented in existing devices such as relays and not need sophisticated equipment. One application of detecting the fault-cleared state is adaptive reclosure in which case, substantial improvement in transmission system reliability and benefits in protection can be achieved. |
