Note: The estimated number of Transformers Banks is based on the counts from the TRAMS database when conversion started and is the basis for density and is also used by RAMTeCH to estimate the level of effort and staffing resources.
Field Verification (Scrubbing)
1. PSNH Retirees - Knowledge of Distribution System
2. AWC schedule - Geographic locations
3. Identified gaps - Data sources
4. Electrical connectivity issues
5. Markups - Preparation for source data submission
6. Open Points - Underground Residential Development
7. Detailed Sector Cabinets
8. Results - Vendor questions reduced
