Protection-Data CommunicationDeactivated
Directional Test
In the case of protection interfaces of type 1 and type 2, the complex phasors of the voltage and current meas-
uring point are exchanged between devices of one communication topology in order to be able to carry out a
directional test during commissioning, for example. DIGSI 5 depicts this in the form of a phasor diagram. You
can only route the measuring point to the protection interface. For 1 1/2 circuit-breaker layouts, a measuring
point can therefore be transferred and checked optionally. You can also check and test the 2nd measuring
point by rerouting. Furthermore, communication with DIGSI 5 can take place via the protection interface to
other devices of the constellation. For this purpose, the protection-interface connection is interrupted and
DIGSI 5 uses this connection for communication with the remote device.

After completing the remote connection by DIGSI 5, the system switches back over to protection commu-
nication.
