Autoreclosing Timeout (ART)
Reclosing will be made only if the voltage from source side of protection device (protection device is Open)
meets the requirements of VRC element. Otherwise, device will not reclose. If the voltage did not recover until
Autoreclosing timeout is expired, protection device will go to lockout.
ART settings are described in Table 60.
