Core function
Medium-voltage switchgear connects, switches, isolates, protects, and monitors circuits above the low-voltage distribution range within a defined system. It may serve ring, radial, transformer, generator, or feeder applications.
What to define
Identify voltage, frequency, current, fault duty, bus and feeder arrangement, breakers or switches, earthing, CT/VT and relay interfaces, cable terminations, environment, access, and control requirements.
Scope boundary
This overview does not assign a voltage class, rating, or protection setting. Confirm the complete assembly with the responsible power-system engineer.
