The parameters for the monitoring of AC analog measurements function are set via the
local HMI or PST (Parameter Setting Tool). Refer to the Technical reference manual
for setting parameters and path in local HMI.
The user can determine the rated parameters for the terminal.
•
Rated frequency fr
•
Position of the earthing point of the main CTs (CTEarth), which determines wheth-
er the CT earthing point is towards the protected object or the busbar
The other basic terminal parameters, related to any single analog input, can be set under
the configuration menu.
The user can determine the base values, the primary CTs and VTs ratios, and the user-
defined names for the analog inputs of the terminal.
U1:
•
ac voltage base value for analog input U1: U1b
•
voltage transformer input U1 nominal primary to secondary scale value: U1Scale
•
Name (of up to 13 characters) of the analog input U1: Name
U2:
•
ac voltage base value for analog input U2: U2b
