Characteristic Curves for the 50N Element
During configuration of the scope of functions at address 126, the available characteristics were determined.
Depending on the selection made there, only the parameters associated with this characteristic curve are
accessible.
The inverse time elements enable the user to select different characteristic curves. Address 126 allows you to
specify whether you work with IEC characteristics 50(N) 51(N) IEC or ANSI characteristics 50(N)
51(N)ANSI).
Bei den stromabhängigen Stufen können verschiedene Kennlinien gewählt werden. Unter Adresse 126 stellen
Sie ein, ob Sie mit IEC-Kennlinien (50(N) 51(N) IEC) oder ANSI-Kennlinien arbeiten (50(N) 51(N)ANSI).
If you work with IEC characteristics, you can select the following setting options at address 2642:
•
Normal Inverse
•
Very Inverse
•
Extremely Inv.
•
LongTimeInverse
If you work with ANSI characteristics, you can select the following setting options at address 2643:
•
Inverse
•
Short Inverse
•
Long Inverse
•
Moderately Inv.
•
Very Inverse
•
Extremely Inv.
•
Definite Inv.
The characteristics and equations they are based on are listed in the "Technical Data". They apply for direc-
tional and non-directional elements alike.
