Adaptive frequency tracking is included to ensure proper operation of the generator
differential protection during varying frequency conditions.

An open CT circuit condition creates unexpected operations for Generator differential
protection under the normal load conditions. It is also possible to damage secondary
equipment due to high voltage produced from open CT circuit outputs. Therefore, it may
be a requirement from security and reliability points of view to have open CT detection
function to block Generator differential protection function in case of open CT conditions
and at the same time produce the alarm signal to the operational personal to make quick
remedy actions to correct the open CT condition.

Generator differential protection GENPDIF (87G) is also well suited to generate fast,
sensitive and selective fault clearance, if used to protect shunt reactors or small busduct.
