SUBSTATION TYPICAL SUBSTATION LAYOUT What is Substation? A substation is an important part of Electric power system. Substation performs many operations like voltage Step-up & Step-Down, measurement of electric quantities, controlling,…., etc.                              OR A substation is an assembly of many electric components connected in series or parallel at one specified distance for stepping up or stepping Down the electrical quantities and measurement and controlling of electric quantities. It may include power generation substation , Power transmission substation And power Distribution Substation . Main Components of Substation Ø Power transformer Ø Circuit breaker Ø Isolator Ø Lighting Arrestor Ø Relay Ø Capacitor bank Ø Earthing Ø Bus-Bar Ø Instrument Transformer Ø Conductors & insulators 1.     Power Transformer POWER TRANSFORMER “ Transformer is a static device which is used to step-up

BLOCK DIAGRAM DESCRIPTION ·         Block Diagram: Fig: Block diagram of the project COMPONENT DESIGN ·         Power supply unit: -                                     To provide a regulated power supply to all blocks a special required power supply is designed for digital IC +5v is achieved for Op-Amp adder is +15V is generated as well as for ADC a signal +10Vis generated power supply. Block consists of transformer the sensor and switches. POWER SUPPLY                     The power supply is the first and the most important part of our project. For our project we require +5v regulated power supply with maximum current rating 500 mA Following basic building blocks are required to the generated power supply. Relay Board : -                              A relay is a device that functions as an electrically operated switch. Most relays is electromagnetically operated. Current through a coil generates a magnetic field that attracts an arm
