P<>
P>, P>> [%Pn]
Threshold for first or second directional power protection stage respectively, indicated in % of
NominMainsPwr. Positive value of power means that the power flows in the direction from mains into
the feeder.
Step: 0,01 %
Range: -300,00 300,00 %
Default setting: 10,00 %
P> Del, P>> Del [s]
Delay for first or second stage of directional power protection stage respectively.
Step: 0,01 s
Range: 0,00 - 150,00 s
Default setting: 5,00 s
P> Direction, P>> Direction [UNDER / OVER]
Setting of the direction of evaluation of mains-reverse power first or second protection stage
respectively.
UNDER: if the power is less then the value of the pre-set limit, the protection trips.
OVER: if the power is higher then the value of the pre-set limit, the protection trips.
Default setting: OVER
Example of a possible setting:
An example of setting of directional power protection is shown on the following case. There is a feeder
of nominal power 200 kW. The protection is supposed to trip when the power flows from the generator
to the mains, exceeds the value by 100 kW (50 % of nominal power of the protected feeder) and flows
for a period of 10 seconds. The setpoints will be adjusted as follows:
P> - 50 % (minus sign due to the power flow to the mains)
P> Del 10 s
P> Direction OVER (the protection must trip when the power exceeds 50 % of the nominal power)
P Trp BO [Trp 1 / Trp 2 / Trp 1+2 / None]
Selection of trip binary output for directional power protection.
Default setting: None
Sync Check
Upper V Lim [%Un]
Defines upper limit for the measured voltage, used to enable the Sync Check function. If the voltage is
above this limit, it is never evaluated as "in synchronism".
Step: 0,1 %
Range: 100,0 - 120 % of nominal voltage
Default setting: 105,0 %
Lower V Lim [%Un]
Defines lower limit for the measured voltage, used to enable the Sync Check function. If the voltage is
under this limit, it is never evaluated as "in synchronism".
Step: 0,1 %
Range: 70,0 - 100,0 % of nominal voltage
