Consider adding a slide summary of devices

4. Definitions (Component Type)

Communications systems necessary for correct operation of protective functions
Voltage and current sensing devices providing inputs to protective relays
Station dc supply associated with protective functions (including station batteries, battery chargers, and non-battery-based dc supply)
Control circuitry associated with protective functions through the trip coil(s) of the circuit breakers or other interrupting devices

5. Definitions (Component Type)
Automatic Reclosing – Includes the following Components:
Reclosing relay
Supervisory relay(s) or function(s) – relay(s) or function(s) that perform voltage and/or sync check functions that enable or disable operation of the reclosing relay

Control circuitry associated with the reclosing relay or supervisory relay(s) or function(s)

6. Definitions (Component Type)
Sudden Pressure Relaying:

7. Legacy PRC Maintenance
Legacy PRC Maintenance and Testing Standards:
PRC b Protection System Maintenance and Testing (inactive 3/31/27)
PRC UFLS Equipment Maintenance (inactive 3/31/27)
PRC UVLS Maintenance and Testing (inactive 3/31/27)
PRC RAS Maintenance and Testing (inactive 3/31/27)
Legacy standards required the entities to establish their own maintenance and testing program, along with their own intervals.

8. Version 2 and 2(i)
There were two version 2 PRC-005 standards that were enforceable:
PRC combined all legacy PRC maintenance standards (005, 008, and 017), and introduced required maintenance activities along with an option for performance-based intervals for Protection Systems (enforceable 4/1/15 to 5/28/15)
PRC-005-2(i) added BES dispersed power producing resources from Inclusion I4 of the BES definition (enforceable 5/29/15 to 12/31/16)

9. Versions Never Enforceable
There were six (6) versions of PRC-005 that were approved but never enforceable:
PRC-005-2(ii) replaced SPS with RAS
PRC included Automatic Reclosing
PRC-005-3(i) added BES dispersed power producing resources
PRC-005-3(ii) replaced SPS with RAS
PRC added Sudden Pressure Relaying
PRC added BES dispersed power producing resources

10. Version 6 PRC-005-6: Incorporates all previous revisions.

21. Transition Documentation
Entities shall maintain documentation to demonstrate compliance with PRC-005-1b, PRC-008-0, PRC-011-0, and PRC until they meet the requirements of PRC in accordance with the IP
Entities shall maintain each of their Protection System components according to their maintenance program already in place for the legacy standards or according to their maintenance program for PRC-005-6
Talking point to the data retention

22. Transition Documentation
While entities are transitioning to the requirements of PRC-005-6, each entity must be prepared to identify:
All of its applicable Protection System components.
Whether each component has last been maintained according to PRC or the legacy standards.
Note: A component maintenance activity is considered transitioned only after the new maintenance activities have been performed.
Talking point: important to have a full list of components

23. Highlights
The legacy PRC maintenance standards remain in effect throughout the transition period (3/31/2027)
PRC & PRC-005-1b are the only remaining standards
The two key IPs are the PRC and PRC-005-6
Maintain documentation from the legacy standards
Continue to maintain components under legacy or new standards
Meet the percentages in the IPs
Percent transition relates to component maintenance activities
Be prepared to identify all components and the last standard under which they were maintained
Talking point – include transition component maintenance activity
