Time setting = Time delay of PSE + Margin
= 12ms + 5ms
= 17ms
c. Time setting of earth fault element EF (TEF)
This time setting is for time delay of the EF element. If it is set to 3s, the trip/alarm contact
will close 3s after detecting an unbalance current (residual current) such as a CT open circuit
fault. In addition to CT open circuit faults, this element can detect a broken conductor
condition.
d. Time setting of directional earth fault relay (TDEFB)
Set the time delay for the directional earth fault element for back-up.
2.12 Autoreclose setting
a. Dead timer reset timing
b. Dead line timer
The SPAR and TPAR timer are provided to present the deionized time of the line. The SPAR
element is initiated simultaneously by the reclose initiation for single-pole autoreclose dead
time. TPAR is for three-pole autoreclose dead time.
c. Reclaim timer
The reclosing command signal is blocked during adjusted time set by reclaim timer, after the
breaker is closed manually or automatically.
d. ARC reset timer
This time element starts to run upon reclosing initiation.
e. ARC output pulse timer
The duration of the reclosing pulse depends on the operation time of the breaker. The required
pulse time is set by this time element.
