B. Leak Inspection • Scope: Inspect leaks for: o 3 Pad Mount Transformers. o 5 Pad Mount Switchgears. o 1 Pad Mount Switchgear (as part of fluid replacement, see requirement C). o 1 Pad Mount Transformer (as part of recommendation for mitigating corrosive deterioration, see requirement D). • Procedure: o Inspect for potential nitrogen leaks. o Provide recommendations for confirmed leaks to include necessary parts and materials. o Verify Pressure Gauge functionality for three (3) Pad Mount Transformers and five (5) Pad Mount Switchgears. • Post-Service: Purge and recharge headspace with dry nitrogen per Standard Nitrogen Recharge Procedure (see requirement E). • Deliverable: Summary of inspections and gauge verification results. C. Fluid Replacement -- 2 of 6 -- STATEMENT OF WORK Dated 6/12/2026 3 • Scope: Replace fluid in One (1) Pad Mount Switchgear. • Procedure: o Remove existing fluid from the tank. o Inspect tank for potential fluid leaks and repair confirmed leaks with necessary parts and materials. o Replace fluid with approved E200 fluid. o Verify pressure gauge functionality for One (1) Pad Mount Switchgear. • Post-Service: Purge and recharge headspace with dry nitrogen per Standard Nitrogen Recharge Procedure (see requirement E). • Deliverable: Report confirming fluid replacement and tank integrity. D. Recommendation for Mitigating Corrosive Deterioration (rust) • Scope: Inspect and provide recommendation for mitigating rust on One (1) Pad Mount Transformer. • Procedure: o Inspect for corrosive deterioration and potential nitrogen leaks. o Provide recommendation for confirmed issues (rust and leaks) to include necessary parts and materials. o Replace gasket. o Verify pressure gauge functionality for One (1) Pad Mount Transformer. • Post-Service: Purge and recharge headspace with dry nitrogen per Standard Nitrogen Recharge Procedure (see requirement E). • Deliverable: Report detailing recommendations for repair and gauge verification. E. Standard Nitrogen Recharge Procedure • Applicability: Necessary for requirements B, C and D after service completion. o 4 Pad Mount Transformers o 6 pad Mount Switchgears • Procedure: o Fill headspace with dry nitrogen to a pressure of 5 psi. o Maintain pressure and verify no change for at least 15 min. o Vent headspace to atmospheric pressure. o Refill headspace with nitrogen to 2‐3 psi. • Requirements: use calibrated pressure regulation equipment and dry nitrogen supply. G. General Comments and Assumptions: • No more than two (2) switches and/or two (2) transformers may be powered down at a time. • NCCIPS Electrical personnel will perform all necessary switching to remove power to switches before service. -- 3 of 6 -- STATEMENT OF WORK Dated 6/12/2026 4 • Schedule for services shall be coordinated with the government’s technical representative not less than five (5) working days prior to performance of services. If downtime is required, work will be scheduled at the earliest convenience of the affected data center clients. • NCCIPS team members will review the Dissolved Gas Analysis (DGA) baseline fluid test reports once the Contractor delivers them. • The Contractor will notify the government’s technical representative of any engineering change notices and any production enhancements. • At the conclusion of each service visit, an electronic re…
