7.7 Directional Overcurrent Protection, Ground
Parameter: Time dial
•
Default setting (_:6) Time dial = 0.2
You can use the Time dial parameter to displace the operate curve in the time direction.
General information cannot be provided. Define the value corresponding to the application.
Parameter: Knee-point
•
Default setting (_:101) Knee-point current = 1.300 A
•
Default setting (_:105) Knee-point time = 23.60 s
You use the Knee-point current parameter and the Knee-point time parameter to define the knee-
point of the operate curve.
General information cannot be provided. Define the values corresponding to the application.
Parameter: Minimum Time of the Operate Curve
•
Default setting (_:104) Min. time of the curve = 0.80 s
•
Default setting (_:102) Current at Min. time = 1.500 A
Via the parameters Min. time of the curve and Current at Min. time, the point of the operate
curve is defined where higher currents do no longer cause shorter operate times.
General information cannot be provided. Define the value corresponding to the application.
Parameter: Maximum Time of the Operate Curve
•
Default setting (_:103) Max. time of the curve = 93.00 s
You can use the parameter Max. time of the curve to determine the initial value of the operate curve
(for 3I0 = Threshold).
General information cannot be provided. Define the value corresponding to the application.
