11.1.1 Identification
Function description
Scheme communication logic for
distance or overcurrent protection
11.1.2 Functionality
To achieve instantaneous fault clearance for all line faults, a scheme communication logic is
provided. All types of communication schemes for example, permissive underreaching, permissive
overreaching, blocking, unblocking, intertrip are available.
