Directional overcurrent definite time function - parameters
Description
Parameter for determining in which set of parameters a particular function is
active.
Defines the CT input channel. Only three-phase CTs can be set.
Defines the VT input channel. Only three-phase VTs can be set.
Pick-up setting for tripping.
Characteristic angle.
Delay between pick-up and tripping.
Time allowed for the directional decision to be received from the opposite end
in a blocking scheme.
Determines the response of the protection after the time set for memorizing
power direction:
• trip
• block
Time during which the power direction last determined remains valid.
