Application configuration of the SMV receiver
TVTR function blocks are used in receiver application to perform the supervision for the sam-
pled values and to connect the received analog voltage inputs to the application. When
SMVRCV is connected to the TVTR inputs, the connected TVTR does not physically measure
its analog inputs if they are available in the protection relay. SMVRCV function block outputs
need to be connected according to the SMV application requirements, typically all three
analog phase voltages connected either to ULTVTR1 or alternatively only a single analog
phase voltage UL1 connected to the ULTVTR2 input. RESTVTR1 input is typically connected
only in case there is measured neutral voltage needed and then available from the sender.

Synchrocheck function requires and uses only single analog phase voltage (UL1) connected to
ULTVTR2.
