CONFIGURING THE BUSBAR PROTECTION
To configure the product to the topology of the busbar, use the settings in the
GROUP X SYSTEM CONFIG
column and map the digital inputs (DDBs) in the Programmable Scheme Logic (PSL). You don’t need to use
special topology design software.
1.
As this is a single-phase device, set the
Protected Phase
to the phase being protected.
2.
The current input circuits are known as terminals. To configure the protection, identify the number of
terminals on the busbar.
3.
Using the system configuration settings, associate the terminals with the primary CT circuits to which
they are connected. Use the bit-field where 1 represents a connection and 0 no connection.
4.
Set the polarities of the CT terminals using 1 or 0.
5.
To complete the configuration, associate the status of switches in the scheme with the digital (opto-
isolated) inputs using the PSL.

Figure 38: Busbar topology used in configuration example.
Before setting the configuration, we need to explain a few things:
●
This is a double busbar scheme consisting of 4 zones.
●
There are 8 current transformers and therefore 8 terminals.
