Answer: A 22kV substation is a critical hub that steps down high-voltage power for local distribution. Essential equipment includes power transformers to convert voltage, switchgear and circuit breakers for protection and control, and various types of insulators and busbars for safe current flow. The proper functioning of these components is vital for maintaining consistent and safe power delivery to end-users.
