Functions
2.27 Jump of Voltage Vector
Time Delays
The time delay T DELTA PHI (address 4603) should be left at zero, unless you wish to transmit the trip indi-
cation with a delay to a logic (CFC), or to leave enough time for an external blocking to take effect.
After expiry of the timer T RESET (address 4604), the protection function is automatically reset. The reset time
depends on the decoupling policy. It must have expired before the circuit breaker is reclosed. Where the auto-
matic reset function is not used, the timer is set to ∞. The reset signal must come in this case from the binary
input (circuit breaker auxiliary contact).
The timer T BLOCK with reset delay (address 4607) helps to avoid overfunctioning when voltages are connect-
ed or disconnected. Normally the default setting need not be changed. Any change can be performed with the
DIGSI communication software (advanced parameters). It must be kept in mind that T BLOCK should always
be set to more than the measuring window for vector jump measurement (2 cycles).
