Substation

Substation

Transformer

  • Power Transformers: Used in transmission substations, these transformers handle high voltages (typically above 36 kV) and large power capacities. They step up or step down voltage for efficient long-distance transmission.

  • Distribution Transformers: Found in distribution substations, these work at lower voltage levels (1 kV – 36 kV) to supply power to homes and businesses.

  • Instrument Transformers:  Specialized transformers used for measurement and protection purposes:

    • Current Transformers (CTs) – Reduce high currents to safe levels for measurement and relay protection.

    • Voltage Transformers (VTs) (or Potential Transformers, PTs) – Step down high voltages to a lower value for accurate monitoring.

  • Autotransformers: A type of power transformer with a single winding that provides voltage adjustment without full isolation between input and output.

  • Isolation Transformers: Provide electrical isolation between circuits to enhance safety and protect sensitive equipment.

Switchgear

  • High Voltage (HV) Switchgear: Designed for voltages above 36 kV, used in transmission networks to handle large-scale power distribution.

  • Medium Voltage (MV) Switchgear: Used for voltages ranging from 1 kV to 36 kV, typically found in industrial facilities and distribution substations.

  • Low Voltage (LV) Switchgear: Used for voltages below 1 kV, mainly in commercial and residential power distribution systems.

Control Cabinet

  • Circuit Breaker Controls: Used to remotely operate and protect power lines.

  • Relay Protection Systems: Detect faults and trigger automatic responses to prevent damage.

  • SCADA (Supervisory Control and Data Acquisition) System:  Allows remote monitoring and control of substation operations.

  • Metering and Measurement Devices: Track voltage, current, and power consumption.

  • Communication Modules: Enable data exchange between substations and control centers.

  • Alarm and Safety Systems: Warn of potential failures or hazardous conditions.
