Plan 30 kV air-insulated switchgear projects using system data, switching duty, insulation boundaries, protection interfaces, enclosure arrangement, cable routing, and handover evidence. Confirm final ratings, code, safety, installation, testing, and qualified engineering requirements for the project.
Define the system boundary
Separate the power equipment, control cabinet, field devices, protection, networks, installer scope, and maintenance responsibility before selecting a configuration or preparing drawings.
Inputs to document
| Input | Why it matters |
|---|---|
| Electrical and operating data | Voltage, current, fault assumptions, operating modes, switching duty, load or feeder information, and protection interfaces. |
| Cabinet and installation | Compartments, mounting, cable entry, clearances, heat, environment, access, labels, grounding, and service sequence. |
| Control and documentation | I/O, terminals, symbols, wire numbers, alarms, revisions, drawings, BOM, settings, test points, and software or data handover. |
| Verification | Inspection points, test records, open decisions, supplier evidence, and acceptance responsibilities. |
Do not copy competitor ratings, certification, safety, performance, or availability claims without project-specific evidence.
