Replacement of 132/33kV Grid Transformers A1MT, A2MTA, A2MTB at 132/33kV Havant Substation
Year
2019/20
Project Scope
Replacement of existing 132/33kV 90MVA and 45MVA transformers in stages. The design scope covers Stage 1 concept design to develop a high-level P&C concept as defined in the Technical Report (TR) and Stage 2 design, creating full detailed designs drawings as agreed in Stage 1 design scope.
Our Scope
- Site visits and data collection, prepare protection notes, battery assessment, review existing settings and protection scheme
- Main Connections Protection drawings and AC & DC detailed design schematics – Red & Green in Stage-by-Stage form
- Preparation IED diagram – Red & Green in Stage-by-Stage form
- Checking of transformer order schedules, specify requirements for loose materials and review manufacturers drawings
- Perform settings calculations, grading studies, provide associated fault study justifications and recommend new settings
- Answering P&C technical based queries within the scope of Stage 1 and Stage 2 and management of Design Review Log
- Upon obtaining design approval from SSE change status of ‘DRAFT’ design drawings to ‘APPROVED FOR CONSTRUCTION’
Our Key Attributes
- Preparation of stage by stage (RED & GREEN) detailed schematic drawings to aid the site modification works
- Identified and resolved gradings issues on the existing settings
