Trigger by Overload

To start a trigger by overload of the Self-Healing Module, the following conditions must be met:

Device's current in phase A greater than the limit of current configured on the Limit Current column of Device_List spreadsheet

Operator's release command to start a sequence of load transfer

Device available for the Self-Healing Module

Good communication quality

 

A trigger by overload may lead to the following actions of the Self-Healing Module:

Transferring the downstream load of the affected device to adjacent Feeders

Turning off downstream loads when there is no possibility of transfer

Performing no action, because there is no downstream load that can be transferred or turned off. In this situation, the Self-Healing Module waits for the next timed protection of the device to perform a turn off
