Setting which determines the elements that will reset the circuit breaker fail time for external protection function initiated circuit breaker fail
conditions.

CB1 I< Set 45 0B 0.05
From 0.02*I1 to 3.2*I1 in steps of 0.01*I1
[Courier Number (current)]
Setting that determines the circuit breaker fail timer reset current for overcurrent based protection circuit breaker fail initiation. This setting
is also used in the pole dead logic to determine the status of the pole (dead or live).
CB2 I< Set 45 0C 0.05
From 0.02*I1 to 3.2*I1 in steps of 0.01*I1
[Courier Number (current)]
Setting that determines the circuit breaker fail timer reset current for overcurrent based protection circuit breaker fail initiation. This setting
is also used in the pole dead logic to determine the status of the pole (dead or live).
ISEF< Current 45 0D 0.02
From 0.001*I3 to 0.8*I3 in steps of 0.0005*I3
[Courier Number (current)]
Setting that determines the circuit breaker fail timer reset current for Sensitive earth fault (SEF) protection circuit breaker fail initiation.

[Indexed String]
Setting that determines the method to be used to declare VT failure.
VTS Status 46 02 Blocking
Disabled
Blocking
Indication
[Indexed String]
This setting determines whether the following operations will occur upon detection of VTS.
• VTS set to provide alarm indication only.
• Optional blocking of voltage dependent protection elements.
• Optional conversion of directional overcurrent elements to non-directional protection
(available when set to blocking mode only). These settings are found in the function links cell of the relevant protection element columns in
the menu.
VTS Reset Mode 46 03 Auto
Manual
Auto
[Indexed String]
The VTS block will be latched after a user settable time delay ‘VTS Time Delay’. Once the signal has latched then two methods of resetting
are available. The first is manually via the front panel interface (or remote communications) and secondly, when in ‘Auto’ mode, provided the
VTS condition has been removed and the 3 phase voltages have been restored above the phase level detector settings for more than 240 ms.
