Product Description
What is a substation?
A substation is an electrical facility that's used to transform voltage levels between high-voltage transmission lines and low-voltage distribution lines.
What are the main functions of a substation?
The main functions of a substation are:
• Transforming voltage from high-voltage to low-voltage levels using transformers
• Switching and isolating transmission and distribution lines using circuit breakers and disconnect switches
• Providing protection for lines and equipment using fuses, relays and circuit breakers
• Metering and monitoring electrical parameters
What types of substations are there?
The main types are:
• Power substations that transform high power from transmission lines to distribution networks
• Distribution substations that further step down voltage to supply industrial, commercial and residential customers
• Converter substations that convert AC to DC or vice versa
