4BRELAY SETTINGS
0BDEVICE CONFIGURATION
Voltage Inhibit (V):
Minimum phase to ground voltage necessary for the
function to activate. For lower voltages the function does not activate.
Block when breaker is open:
Used to block the function when the breaker
or current flow in phases are not present.
3.4.1.10.2. FREQUENCY DERIVATIVE (81D)
The adjustment parameters of this function are:
Enable:
Enables/disables the function. If it is not enabled, it is not
evaluated.
Max. Supervision Freq. (Hz):
Maximum supervision frequency is the
highest frequency value to be supervised.
Min. Supervision Current (A):
For lower current values the function is not
activated.
Pickup value (Hz/s):
It is the frequency difference per time unit for the
function to start.
Definite time (s):
Time to trip after pickup.
Pickup cycles number:
Minimum number of cycles for the unit to start.
3.4.1.11. DIRECTIONAL POWER (32)
The Figure 3-39 shows the configuration window for this function. The configuration
parameters are:
Enable:
Enables/disables the function. If it is not enabled, it is not evaluated.
Pickup (W):
Pickup power level (W).
Definite time (s):
Time to trip after pickup.
Different phase settings:
If this option is checked, it is possible to adjust this
function independently for each phase. In Figure 3-39 this option is disabled.
