How Does a Box Type Substation Work?
A Box Type Substation performs three primary functions:
-
Step-down voltage transformation (High Voltage → Low Voltage)
-
Power distribution to multiple circuits
-
Protection & monitoring of electrical systems
Power Flow Process
-
High-voltage input (10kV-35kV) enters through ring main unit
-
Transformer reduces voltage to 400V/230V for consumer use
-
Low-voltage switchgear distributes power to end users
-
Protection devices (circuit breakers, relays) ensure safety
