Substation Designing

1. Primary (AIS/GIS) Substation Design
2. Candidates should demonstrate endtoend design for voltages in the 33400 kV range, including:

• Single Line Diagrams (SLDs), General Arrangement, layout & section drawings
• Equipment selection (disconnectors, circuit breakers, CT/VT, transformers, switchgear)
• Cable trench / routing, illumination layouts, BOM & asbuilt deliverables
• Practical experience across AIS/GIS substations and site interfaces

1. Secondary (Protection & Control) Engineering
2. Look for:

• CRP/relay scheme design, detailed wiring/schematic diagrams
• Cable schedules, CT/VT adequacy checks, settings coordination
• SCADA/HMI integration (e.g., IEC 608705104, MicroSCADA SYS600, PRP)
• Familiarity with ABB/GE/Siemens/Hitachi relay families and substation comms/OT practices

1. Earthing & Compliance
2. Preference for candidates who can produce earthing grid designs and reports (EPR, touch/step potential) and demonstrate compliance against utility standards.
3. Tools
4. Proficiency in AutoCAD / MicroStation for substation deliverables (EPLAN can be a plus, but profiles focused solely on controlpanel drafting wont suffice for this role).
5. Utility/Standards Exposure (added benefit)
6. Prior work with UK DNO/Transmission (e.g., National Grid) and familiarity with 33 kV connection guidance and submission packages.

Current screening outcome (for context)

In the latest batch, the majority of profiles were rejected due to being controlpanel/EPLAN heavy and lacking dedicated substation design scope.

Request to TA (search keywords / filters to use)

Please source profiles with combinations of the following terms in the CVs or summaries:

• AIS/GIS substation + SLD + GA + layout/section + BOM
• Protection & Control + CRP + schematics/wiring + CT/VT adequacy + relay settings
• SCADA + IEC 608705104
• Earthing grid + EPR/touch/step potential + earthing report
• Voltage tags: 33 kV/66 kV/132 kV/220 kV/400 kV
• Tools: AutoCAD (CDEGS optional)
