33KV GIS Oil Immersed Power Transformer Station For railway and Highway
Product Description
What major equipment is found in a substation?
The major equipment includes:
• Transformers
• Circuit breakers
• Disconnect switches
• Surge arresters
• Capacitors for reactive power compensation
• Current and potential transformers
• Meters and relays
• Control and protective devices like fuses
What safety measures are used in substations?
The key safety measures include:
• Fencing and physical security to restrict access
• Personal protective equipment like insulating gloves, mats, and coveralls
• Control systems to automate and monitor operations remotely
• Installation of fire protection systems like CO2 flooding
• Strict operational and maintenance procedures
Types of substations:
• Generator step-up substations connect power plants to transmission systems. They have the highest voltage levels.
• Transmission substations decrease voltage for easier transmission over long distances.
• Distribution substations further reduce voltage to medium voltage levels for industrial usage.
• Unit substations integrate transformers and switchgear to serve a single customer.
