Template Relay Settings File

The SEL-751 Protection Relay, and the Aderis ClearSky’s intended operational behaviors rely on logic programmed into the relay’s RDB settings file.

Aderis provides template RDB files that should be used as a starting point for any Customer specific protection elements, or reclosing behaviors.

ClearSky RDB template files include:

  1. Repair Service vs. Automatic Mode
  2. Power Supply & UPS Battery TRIP
  3. Single Phase TRIP Support

ClearSky RDB template files require customer settings to support:

  1. Interconnection protection element assignment and settings are required to be programmed by the Customer
  2. Interconnection reclosing behavior settings are required to be programmed by the Customer
