  • A PRACTICAL TRANING SEMINAR
    • BY:-Ramveer Olan
  • Sub-station is a subsidiary station of an electricity generation , transmission and distribution system where voltage is transformed from high to low or low to high voltage using transformers.
    • Sub-station should be located at load center
    • Sufficient land area
    • Grounding
    • Easy of maintenance
    • Possibility to Expand
    • Reliability and Security
    • Electrical design considerations
    • EQUIPMENTS OF SUB STATION :
    • Lightning Arrester
    • Wave traps
    • Isolator
    • Instrument Transformers
    • Power Transformer
    • Insulator
    • Circuit Breaker
    • Power Line Carrier
    • Communication (PLCC)
    • Lightning Arrester :-
    • To discharge lightning over voltages and switching over voltages to earth.
    • Wave Trap :-
    • To prevent high frequency signals from entering other zones.
    • Isolators :-
    • Disconnection under no-load condition for safety, isolation and maintenance.
    • TYPES OF ISOLATOR
    • BUS ISOLATOR
    • LINE ISOLATOR
    • TRANSFORMER ISOLATING
    • SWITCH
    • TRANSFORMER
    • A TRANSFORMER IS A STATIC AC DEVICE WHICH CONVERT
    • ELECTRIC ENREGY FROM ONE FORM TO ANOTHER
    • 1.INSTRUMENTAL TRANSFORMER
    • CURRENT TRANSFORMER
    • A C.T IS USED TO STEP DOWN CURRENT FOR
    • MEASUREMENT,CONTROL AND PROTECTION
    • POTENTIAL TRANSFORMER
    • A P.T IS USED TO STEP DOWN VOLTAGE FOR MEASUREMENT, CONTROL AND PROTECTION
    • 2.POWER TRANSFORMER
    • 1.CORE TYPE
    • 2.SHELL TYPE
    • Current Transformer :-
    • To step-down currents for measurement, control & protection.
    • Power Transformer :-
    • To step-up or step-down the voltage and transfer power from one a.c. voltage another a.c. voltage at the same frequency.
    • TRANSFORMER COOLING
    • Natural cooling
    • Oil blast cooling
    • Forced oil cooling
    • Forced air cooling
    • TRANSFORMER USED
    • There are 5 transformer are used in grid sub station
    • 1.220/132 (i) & (ii)
    • 2.132/33 (i) & (ii)
    • 3.132/11
  •  
    • Circuit Breaker :-
    • Automatic switching during normal or abnormal conditions.
    • CIRCUIT BREAKER
    • Minimum oil Circuit
    • Breaker
    • Air Blast Circuit Breaker
    • SF 6 Circuit Breaker
    • Vacuum Circuit Breaker
    • POWER LINE CARRIER COMMUNICATION (PLCC)
    • Wave trap
    • Coupling Capacitor
    • EARTHING
    • Neutral Earthing
    • Electric Earthing
  • PLEASE SAVE ELECTRICITY
  • QUERY ?
