A pre-configured XLSM (workbook) file is distributed by the instructor for this Training. Let's configure only the Device_List spreadsheet with information displayed on the next figure and list. Create a row for each device created on the EDB file of the electrical model.

Consider that the limit of current of each device is equal to 200A.

For the Min/Max Dev Down Gx columns, users must analyze the circuit in each one of the possible scenarios, for each device. Consider the following example as a reference:

On protection group 1 (one), Recloser RL01 does not contain any closed downstream device, because it is implicit that Recloser RL02 is open, therefore Min is equal to 0 (zero) and Max is equal to zero (0)

On protection group 2 (two), it is implicit that Recloser RL02 is closed, that is, Min is equal to 1 (one). Add to this the other two downstream devices on the circuit sequence, RL03 and 5201, therefore Max is equal to 3 (three)

On protection group 3 (three), with a reversed current flow, the only downstream device is Breaker 5201 from Substation SUB01, which can be open or closed and, therefore, Min is equal to 0 (zero) and Max is equal to 1 (one)

Consider that devices RL01 and RL02 have a type Nulec_ADVC2 and device RL03 have a type Cooper_F6.

Drivers from devices RL01, RL02, and RL03 must be named as "FE01_RL01", "FE01_RL02", and "FE02_RL03", respectively.

As we are creating a separated Slave Driver for each device, the slave address, configurable on the DeviceDNP3 column, can be equal to 1 (one) for all devices.

Similar to the previous item, the DNP3_SH_OffSet_N4 column can be equal to 0 (zero) for all devices, because there is no more than one Breaker in each Substation and, therefore, there is no conflict on the addresses configured in the Driver.

Consider that devices contain a Measurement to indicate a lockout of the reclosing cycle.

Configure the self-healing mode of the devices to automatic, that is, the SH Automatic Mode column with the value S, to test the module later.

Consider that we are not going to implement a configuration for de-energizing a Bar.

Consider that devices do not support a momentary loop.

Reclosers must have their adjustment group changed during the Self-Healing Module triggering.

Consider that devices do not detect a passing current.
