5. The System Restoration Program (SRP) at GEC is utilized to maintain our Distribution and Transmission Systems as well as Substations. This program includes all elements of system maintenance. The program specifically addresses poles and structures, conductors, grounding, guying and inspection. Additionally the SRP includes testing, maintenance and inspection of substations. Power Supply System Restoration

6. The SRP was established to ensure that each and every mainline section undergoes system restoration within approximately an 8 year period. Work is divided such that approximately 1/8 of the circuits are worked each year. Phase 1 restoration (Mainline) focuses on 3 Ø line sections that are connected directly to the supplying substation. Sections of those circuits that are downstream of three Ø or single Ø line breakers, are considered part of the mainline. Phase 2 focuses on sections of the circuit that are fused, regardless of the number of phases, are generally considered to be taps. Any exceptions regarding the sections of circuits included in each phase will be handled on an individual basis. Power Supply System Restoration Schedule

8. Line Breakers (OCR’s): Line breakers are addressed in the Oil Circuit Breaker Change-Out Program. Under this program, each OCR is replaced with a new/rebuilt Oil Circuit Breaker every five (5) years. Power Supply System Restoration Schedule

9. Line Regulators Line regulators are addressed in the Regulator Maintenance Program. Under this program, each regulator is maintained and tested every four (4) years. Additionally, each line regulator is inspected and operationally checked every quarter. Power Supply System Restoration Schedule

10. Right of Way Trimming Vegetation management on the GEC system is completed, by circuit, at a fixed cost to GEC. All GEC circuits are trimmed within a three year cycle. Power Supply System Restoration Schedule

12. Transmission System Program Each transmission line is aerially inspected on an annual basis. Items that are identified during this inspection are classified into two categories. Category 1 consists of those items that must be addressed prior to the next inspection. Category 2 items are less critical and are recorded on the inspection form for future reference. Items in this category are given special attention during subsequent inspections and are corrected as required. Power Supply System Restoration Schedule

13. Substation Program Substations are inspected two (2) times per month. One inspection is a visual inspection of the overall facility; the other inspection includes operational checks of equipment. Substation batteries are tested quarterly. Problems encountered or observed in any of these inspections are budgeted, scheduled and corrected. Problems that are deemed critical are corrected immediately. Power Supply System Restoration Schedule
