ARC_SUB_COND. For example, when changing network conditions downstream
of the line requires no voltage check (VCHK) for reclosure, then the user can
configure the same through PLC by using the ARC_SUB_START and
ARC_SUB_SOND signal inputs.
Dead time for second shot ([TD_MS2]): 0.33s
The same criteria as for the first shot apply for determining the dead time for the second shot.
However, as per the requirement of the CB, the minimum time before a second successive
closure is 0.3s. The [TD_MS2] time has been set at 0.33s including a margin.
ARC command pulse width ([TCCW]): 0.1s
The ARC command pulse width should be set higher than the closing time of the CB. As the
CB closing time is 80ms, the [TCCW] timer is set to 100ms to include a margin.
Note: The difference between the setting [TCCW] and the CB closing time, (in this case
20ms) should be lower than 'the protection operation time + CB opening time'.
This is to ensure that for CBs without an anti-pumping feature, the close pulse is
not present if the CB were to re-trip on closure.
Check time for successful reclosure ([TARCDSUC]): 0.25s
As explained under Chapter 2.22.2(xi), the [TARCDSUC] timer signals the following:
[ARC-SucChk]=Off; the [TARCDSUC] timer signals a successful reclosure. However, it
does not differentiate between a successful reclosure and a CB failure to close.
[ARC-SucChk]=On; the [TARCDSUC] timer signals a CB failure to close condition.
Setting of TARCDSUC timer should be higher than the time required to determine a successful
CB closure; that is, higher than protection operating time + CB opening + dead time + CB
closing time. In this case it should be > (45ms + 60ms + 105ms + 80ms); that is, > 290ms.
Setting chosen is 350ms.
Time for resetting upon CB failure ([TRESET]): 0.15s
The setting for [TRESET] should be longer in duration than the CB opening time. In this case,
it should be > 60ms. Setting chosen is 150ms.
Abandon time for ARC SHOT1 ([TRR]): 0.15s
The setting of [TRR] should be longer in duration than the [TSHOT/TSHOT_SUB] timer
settings. In this case, it should be set > 125ms. Setting chosen is 150ms.
