Siemens SIPROTEC 5 User Manual

The function group has the following interfaces with the measuring points:
•
1-phase voltage
The 1-phase voltage is provided via this interface. All values that can be calculated from the measurands
are also provided via this interface.
•
1-phase current
The 1-phase current is provided via this interface. All values that can be calculated from the measurands
are also provided via this interface.

Equipment Data
The rated voltage and rated current as well as the neutral-point treatment of the object or the equipment are
defined here. These data apply to all functions in the Voltage/current 1-phase function group.
Reset the LED Group
Using the Reset the LED group function, you can reset the stored LEDs of the functions in one specific func-
tion group while the activated, stored LEDs of other functions in other function groups remain activated.
