Diagnostic
Leave an initial condition or reset condition (Pickup)
Operation (with operate time)
Duration of time interval between the instant when the character-
istic quantity in reset condition is changed, under specified condi-
tions, and the instant when the relay operates
The ratio of a reset value to an operate value in well-specified con-
ditions. The dropout ratio may be lower or greater than 1 according
as an over or under element is considered
Duration of the time interval between the instant when the charac-
teristic quantity in operate condition is changed, under specified
conditions, and the instant when the relay operates.
The stated reset time is related to a step variation of characteristic
quantity in operate condition to the reset condition.
The critical impulse time for a relay which is in its reset condition,
is the longest duration a specified change in the input energizing
quantity(ies) (characteristic quantity), which will cause the relay
to change to operate condition, can be applied without the relay
switches. The overshoot time is the difference from the operate time
and the critical impulse time.
The declared values for the overshoot time are applicable with the
lower setting value of the operation time.
